Installing a LightStream 2020 multiservice ATM switch (LS2020 switch) in a networking environment involves several tasks in two major categories:
Separate sections in this chapter are devoted to the following topics:
Detailed site planning and preparation information can be found in the LightStream 2020 Site Planning and Cabling Guide.
Detailed information for installing additional components in an existing LS2020 switch is provided in this document in the chapter entitled "Installing Additional Components."
Basic configuration tasks for the LS2020 switch are accomplished using configuration scripts. These procedures are presented in this chapter in the section "Basic LS2020 Configuration Tasks."
Before continuing with this chapter, you should read the LightStream 2020 Release Notes for important, release-specific information that may not appear elsewhere in the LS2020 documentation set.
Static electricity can damage or degrade electronic components. Therefore, observe the precautions described below in handling LS2020 hardware.
Before removing any part of the LS2020 enclosure to expose its circuitry, you must ensure that you, the equipment rack, and the circuit boards are at ground potential to prevent electrostatic discharge (ESD). Such spurious discharges can damage LS2020 components. To place yourself at ground potential, wear a wrist strap connected to one of the ESD grounding jacks on the front and rear of the LS2020 chassis or to the bare metal chassis frame itself.
All spare cards are shipped in a separate, reusable antistatic shielding bag. Store each card in its bag until the card is installed in the machine. Do not remove a card from its bag unless you are grounded. Do not place a bag on exposed electrical contacts where it can cause short circuits.
To unpack the LS2020 switch, perform the following steps:
Step 2 Transport the container to the systems area where the LS2020 switch is to be installed.
Step 3 Cut the packing straps and lift the cardboard box off the LS2020 chassis. Remove the packing material.
Step 4 Check for the presence of the power cord and country kit.
Step 5 Inspect all external surfaces of the chassis for signs of damage. Pay special attention to areas of the chassis corresponding to visible damage to the shipping container.
Step 6 Document any damage noted during the inspection.
Step 7 Advise your LS2020 vendor of such damage.
This section explains how to mount an LS2020 chassis in an equipment rack.
Note For physical stability, when an LS2020 chassis is installed in a rack, the equipment configuration should comply with UL Standard 1950, Par. 4.1.1, and IEC 950, 4.1.1.
An LS2020 chassis takes in cooling air at the bottom of the front panel and exhausts it at the top rear and right side of the chassis. (The air vents on the right side of the chassis can safely be covered by the rack side panels, but they should not otherwise be blocked.) To minimize the potential for thermal problems, position the LS2020 chassis so that:
Ensure that you have the following items on hand before you begin installing the LS2020 switch:
To mount the LS2020 switch in an equipment rack, perform the following steps:
Step 2 Put on the ESD wrist strap and connect it to a grounding jack on the front or the rear panel of the LS2020 chassis.
Step 3 Reduce the weight of the system by removing the blowers (top front and top rear) and power supplies (right rear) from the chassis.
These components are located behind removable covers. Figure 2-1 shows the front view of the LS2020 chassis, while Figure 2-2 shows the rear view of the chassis.
If your system is fully configured with function cards, you may also remove some or all of these cards to further reduce the weight of the chassis. (Refer to the LightStream 2020 Hardware Reference and Troubleshooting Guide for component removal instructions.) Put all removed electronic components in antistatic shielding bags or place them on antistatic mats.
Step 4 Determine the desired mounting position in the rack for the LS2020 switch. Attach the clip nuts from the country kit or the rack mounting kit to the appropriate positions on the rack rails.
See Figure 2-1 for the location of mounting screw slots. (If your rack has metric-threaded or non-standard rails, you may need to provide your own mounting hardware.)
Step 5 Lift the LS2020 chassis into the desired mounting position in the rack.
| Caution Do not use the disk assembly handles to lift the chassis. These handles, shown in Figure 2-1, are not designed for weight-bearing loads and may break off if used to lift the chassis. |
Step 6 Using the mounting screws and washers included in your country kit or rack mounting kit, secure the flanges on the front of the LS2020 chassis to the rack.
Step 7 Replace any items that you removed from the chassis in Step 3 above (blowers, power supplies, function cards, and covers) preparatory to installing the chassis into the rack.
The procedure in this section explains how to wire a DC-powered LS2020 switch to a DC power source. This task should be performed only by qualified service personnel or a licensed electrician.
This section applies only to systems with the DC power option. If you have a standard AC-powered system, skip to the section "Installing Fantails ."
For general information on DC-powered LS2020 systems, see the LightStream 2020 Hardware Reference and Troubleshooting Guide. For power specifications, see the LightStream 2020 Site Planning and Cabling Guide.
Note the following in preparation for wiring a DC-powered LS2020 switch:
| Warning The wiring task should be performed only by a licensed electrician or qualified service personnel. Untrained personnel may be exposed to hazardous DC voltages. |
To wire a DC-powered LS2020 switch to a DC power source, perform the following steps:
Step 2 Ensure that power to the circuit to which you will connect the LS2020 switch is OFF.
Step 3 Connect the three system power wires to the LS2020 terminal block, using the slot-tipped screwdriver to secure the terminals. Do not remove the terminal covers at the base of the terminal block.
Step 4 To connect the alarm circuit, remove the plastic terminal block cover (see Figure 2-3) and set it aside for the time being.
Step 5 Connect the alarm wires to the LS2020 terminal block, using the Phillips screwdriver to secure the terminals.
Step 6 Replace the terminal block cover.
Step 7 Repeat the procedure above if the LS2020 switch contains a second DC power tray.
Step 8 Observe the green power LED on the front of the power tray when power is applied. If the LED is not lit, check for incorrectly connected wires or problems in the DC power source.
This section explains how to mount and connect fantails in your LS2020 switch (see Figure 2-4). Fantails provide connectors for data cables on low-speed (V.35, X.21 and RS-449) lines and T3 lines that are attached to cell line card/T3 access cards in an LS2020 switch.
If your system has no low-speed or cell line card/T3 modules, skip to the section "Attaching Data Cables ."
Note RS-449 refers to a popular physical layer interface standard that is now called EIA/TIA-449. However, to avoid confusion in this document, the "RS-449" nomenclature will be retained when describing the components and capabilities of an LS2020 switch.
Obtain the following equipment and tools in preparation for installing fantails:
Note If you are installing X.21 fantails and you plan to configure the ports as DTEs, you must obtain and install a 15-pin male-to-male gender converter on each port in order to change the female connector to a male connector. Note, however, that the gender converters are not required for X.21 ports configured as DCEs.
To install fantails in your LS2020 switch, perform the following steps:
Note Before installing fantails, check the interface jumpers on each low-speed access card. These jumpers must be set to the interface displayed on the fantail(s) for that card. For instructions on setting interface jumpers, see the LightStream 2020 Hardware Reference & Troubleshooting Guide.
Step 2 Put on the ESD wrist strap and connect it to the ESD jack on the rear of the LS2020 chassis.
Step 3 Attach the fantail cable(s) to the back of the fantail and the corresponding access card in the chassis. (Performing this task now is recommended, rather than installing the fantail first and having to reach behind it to attach the cable(s) to a connector that you cannot observe directly.) Note that the cable is reversible; that is, either end of the cable can be connected to the fantail. Exercise care to avoid suspending the weight of the fantail on the cable.
Step 4 Attach the fantail to the rails with the mounting screws and washers provided, using a slot-tip screwdriver.
Step 5 Label the fantail with the slot number or the name of the interface module to which the fantail is connected.
Step 6 Repeat Step 1 and Steps 3 through 5 to install additional fantails in your LS2020 switch.
Note If you are mounting an X.21 fantail, set the DTE/DCE switches for each port to the desired mode. (See the LightStream 2020 Hardware Reference and Troubleshooting Guide for more detailed instructions on configuring X.21 ports as DTEs or DCEs.) If you select a DCE interface, note that you must install a gender converter on each DTE port in order to change the female connector to a male connector.
To attach data cables to your LS2020 switch, perform the following steps:
Step 2 If you have any OC-3c or FDDI cards in your LS2020 switch, remove and save the protective covers on the ports that will be used. Leave any unused ports covered.
Step 3 If you have any E1 CEMAC cards (circuit emulation access cards) in your LS2020 switch, check the user-settable jumper settings on the card(s). These jumpers allow you to select termination impedance and grounding on the receive line, as well as the pulse amplitude and grounding on the transmit line.
As default values, the termination impedance and pulse amplitude jumpers are set to 120 ohms, and the transmit and receive lines are not grounded. Use these default settings if you plan to use the E1 CEMAC card without a fantail. However, if you do plan to use a fantail (which provides 75-ohm interfaces), you must use 75-ohm settings for termination impedance and pulse amplitude and set grounding to on.
For more detailed information about changing the E1 CEMAC card jumper settings, consult the LightStream 2020 Hardware Reference and Troubleshooting Guide.
Step 4 Connect any available external data cables. (Refer to the LightStream 2020 Site Planning and Cabling Guide for details about data cables and connectors.) If you have Ethernet cards in your LS2020 switch, note that each card supports only eight ports (0 through 7), although 10 physical connectors are available on the access card. Note also that you can use only one of the 10Base-T or AUI connections on ports 0 and 7.
Note For ease of maintenance, route cables at the back of the LS2020 chassis in a way that enables you to later remove any access card without disconnecting cables attached to other access cards or fantails.
Before applying system power, check the front and back of the system to ensure that all boards, disks, blowers, bulkheads, filler panels, and covers are in place and secured firmly to the chassis frame. When in place, these items form an enclosure that serves three important functions:
You can power your LS2020 switch with either an AC or a DC power tray. In addition, you can equip your LS2020 switch with an optional (redundant) power tray of like type (see Figure 2-5).
To power up an LS2020 switch, perform the following steps:
If your system is equipped with a second AC power tray, repeat Step 1 for this tray.
Step 2 If you have a DC-powered system, flip the DC power switch located on the power tray panel to the up position. (This step assumes that your LS2020 switch has already been connected to a DC power source by qualified service personnel or a licensed electrician, as described in the section "Wiring a DC-Powered System ").
If your system is equipped with a second DC power tray, repeat Step 2 for this tray.
Note When the LS2020 switch is powered up, the blowers start running and the test and control system (TCS) applies power to the cards and initiates the power-on self test (POST) sequence. LEDs on the power tray(s) and the individual cards indicate operational status, as reflected in the flow chart in Figure 2-6. The power-up sequence, including the POST, takes a minute or less.
Step 3 If the green ready (RDY) LED on each card lights up (indicating operational status), proceed to the next section "Installing Modems." If a yellow fault (FLT) LED stays lit on any card, indicating the existence of a problem, do either of the following:
You should obtain and install a modem for each switch card in the LS2020 chassis. In the event that an operational problem causes a node to be isolated from the rest of the network, the modem may be the only means available for communicating with that node.
The modem connects to the modem port on the modem/console assembly bulkhead at the back of the LS2020 chassis, using the modem cable described in the LightStream 2020 Site Planning and Cabling Guide.
A modem attached to an LS2020 node must be a V.42 Hayes-compatible unit capable of operating at 2400 baud. The following modems are compatible with the LS2020 switch:
For information on the default modem port settings and how to change them, see the LightStream 2020 Network Operations Guide.
This section explains how to enter basic configuration information for your LS2020 chassis in order to make it operable in your networking environment and manageable from your NMS. You must perform these procedures for the NP card(s) in your LS2020 chassis.
Note If you experience a problem while performing basic configuration tasks, you may need to shut down and restart the system. Refer to the LightStream 2020 Hardware Reference & Troubleshooting Guide for instructions on performing an orderly shutdown.
You need to have at hand the following information before beginning the LS2020 basic configuration procedures:
The following sections describe in greater detail the information required for basic LS2020 configuration.
You must create a password for each of the four default login accounts on the LS2020 switch: root, oper, npadmin, and fldsup. See the LightStream 2020 Network Operations Guide for more information about default login accounts.
A password must be at least six characters in length. It can be as long as you wish, but only the first eight characters are used. Any combination of characters is acceptable, including spaces.
You must assign a unique host name to each LS2020 node. Typically, a name can be chosen to reflect the node's geographic location (for example, Tokyo2) or its function within an organization (for example, mfg3).
The name may consist of any combination of letters and numbers up to 32 characters, but it must not begin with a number. Thus, Pensacola23 is a valid host name, but 23Pensacola is not; similarly, Pensacola.23 is not a valid name, since it contains a character other than a letter or number.
For each LS2020 node, you must provide from one to four IP addresses and associated network masks, as described below:
Nodes in an LS2020 network use their primary NP addresses to communicate network management traffic to each another.
Note All NP addresses within the same LS2020 network must have the same network number, and each node must have a unique host ID.
The subnet mask specifies which portion of the IP address is the network number and which portion is the host ID. This mask should be configured to be the same for all nodes in a given LS2020 network.
If a node has a second (backup) NP, the node uses its primary and secondary NP addresses to pass network management traffic between the two NPs within the node. The primary NP address is used by whichever NP is active.
Note All NP addresses within the same LS2020 network must have the same network number, and each node in the network must have a unique host ID.
An Ethernet LAN may be attached to the NP for communicating network management traffic between the node and the NMS. If an Ethernet LAN is connected to the NP, the NP's Ethernet IP address must be configured. If a backup NP is present in the chassis, both NPs must be attached to the same Ethernet segment. The NP's Ethernet IP address is used by whichever NP is primary (active).
Note This Ethernet IP address has the network number of the attached Ethernet LAN (which must be different from the network number of the LS2020 network). The Ethernet IP address also has a host number that is assigned by the Ethernet LAN administrator.
The subnet mask for the NP's Ethernet address specifies which portion of the IP address is the network number and which portion is the host ID. This mask is the same for all nodes on the Ethernet LAN attached to the primary NP. You can obtain the subnet mask from the Ethernet LAN administrator.
If an Ethernet LAN is attached to the primary NP, but the NMS is not directly connected to that Ethernet LAN, a default router can be configured as the means for communicating network management traffic between the NP and the NMS. The IP address for the default router has the same network number as the attached Ethernet LAN (this number must be different from the network number of the LS2020 network). The IP address for the default router also has a host number assigned by the Ethernet LAN administrator.
If you plan to operate with a single physical LS2020 network under your network number and the LS2020 network is a class C network, record 255.255.255.0 as the subnet mask. (For a class B network without subnetting, record 255.255.0.0 as the subnet mask; for a class A network without subnetting, record 255.0.0.0 as the subnet mask.)
Note Network management can also be accomplished by means of an Ethernet LAN connected to an ordinary Ethernet data port (that is, an Ethernet access card port) on the LS2020 node. The NMS, however, must be attched directly to that Ethernet LAN. In this case, do not configure the NP's Ethernet address or default router address. Furthermore, in the current release, to provide access control over Ethernet ports that can be used by an NMS, a port configuration parameter has been added which allows you to specify whether IP traffic destined for an NP is forwarded or blocked. This configuration parameter, lsLanPortNPTrafficFilter, determines whether or not inbound frames received on an Ethernet port are delivered to any NP in the network. The default value of this parameter for all access card Ethernet LAN ports is to block IP traffic to an NP. Therefore, you must explicitly set this parameter, on a port-by-port basis, to forward traffic to an NP. The Ethernet ports on the NP access cards remain unaffected in the current release, that is, these ports always pass IP traffic to the NP.
For detailed information about configuring Ethernet port attributes, see the LightStream 2020 Configuration Guide. For detailed information about IP addresses, subnet masks, and network classes, see the LightStream 2020 Site Planning and Cabling Guide.
For each trunk port that you configure, the following information is required:
For more information about trunk port configuration, refer to the LightStream 2020 Configuration Guide.
The procedures in this chapter make use of the following TCS hub commands:
These commands and their associated arguments are described in greater detail in this section wherever the TCS hub commands are used in specific procedures.
This section tells you how to attach a terminal to the console port of a Release 2 switch card. It also tells you how to match the baud rate between the terminal and the console port on the switch card.
You need the following equipment to perform the procedures in this section:
Prior to Release 2.1 of the LS2020 platform software, the TCS hub code for a Release 2 switch card (SC2) supported baud rate selection for both the console and modem ports through what was called the "BREAK" detection mechanism (also referred to as the "auto-baud" or "pseudo-auto-baud" mechanism). Use of this mechanism, which involved multiple activations of the Break key for baud rate selection, is no longer supported. Under this previous scheme, the midplane EEPROM locations used to maintain the console and modem port baud rates were "reserved" and, hence, not initialized with appropriate default values.
Now, when new TCS hub code is installed in a Release 2 switch card that has not had these "reserved" locations initialized, the new code evaluates the contents of these EEPROM locations and initializes them, if required, with appropriate default values. See the section below entitled "Setting Console/Modem Baud Rates through TCS Hub Commands" for these default values and the order of precedence for other possible baud rates for the console and modem ports.
To detect and set baud rates for the console and modem ports for Release 2 switch cards, you use the TCS hub show and set commands, respectively. These commands interpret and manipulate the contents of specific fields in the midplane EEPROM used for storing initialized baud rates for the console and modem ports.
Note Baud rate detection and selection for the console and modem ports apply only to Release 2 switch cards.
The general form of the TCS hub show command for baud rate detection is outlined below:
TCS hub<<A or B>> show <sa | sb> <console | modem> baudrate
TCS hub<<A or B>> Is the TCS hub prompt for the switch card (either switch card A or B, as appropriate).
show Is the command that operates in conjunction with command arguments to display the baud rate for the specified switch and the specified port.
<sa | sb> Denotes that the show command is to apply to switch card A or B, whichever is specified.
<console | modem> Denotes that the show command is to apply to the console port or the modem port, whichever is specified.
baudrate Displays the baud rate for the specified port.
The general form of the TCS hub set command for baud rate selection is outlined below:
TCS hub<<A or B>> set <sa | sb> <console | modem> baudrate <rate>
TCS hub<<A or B>> Is the TCS hub prompt for the switch card (either switch card A or B, as appropriate).
set Is the command that operates in conjunction with command arguments to set the baud rate for the specified switch and the specified port.
<sa | sb> Denotes that the set command is to apply to switch card A or B, whichever is specified.
<console | modem> Denotes that the set command is to apply to the console port or the modem port, whichever is specified.
baudrate Indicates that the set command is to set the baud rate for the specified port.
<rate> Defines the actual baud rate for the specified port.
The following is the order of precedence of the baud rate for the modem port on a Release 2 switch card:
The following is the order of precedence of the baud rate for the console port on a Release 2 switch card:
Note The console port baud rate can be changed at any time, but the change will take effect only on power-up of the LS2020 chassis or a reset of the applicable switch card. Similarly, the modem port baud rate can be changed at any time, but the change will take effect only on power-up of the LS2020 chassis, a reset of the applicable switch card, or when the modem port is reinitialized via the TCS hub init command.
If the modem port on a Release 2 switch card (SC2) is initialized with a baud rate other than that with which the modem can operate, you can change the modem port baud rate through either of two methods, whichever is appropriate for your LS2020 configuration:
If you have access to the local console, perform the following procedure to match the modem port baud rate:
where {sa | sb} represents either Release 2 switch card A or B, as appropriate, and {2400 | 9600} represents the available choices in matching the modem port baud rate.
Step 2 Issue the init command at the TCS hub prompt:
If you do not have access to the local console, but you can dial into the LS2020 chassis by means of a switch card, perform the following procedure to match the baud rate of the desired modem port:
Step 2 Issue the set command at the TCS hub prompt, as shown below:
In this command, specify the switch card having the non-matching baud rate. For example, if you have dialed into the LS2020 chassis through switch card A, specify sb in the set command; if you have dialed into the chassis through switch card B, specify sa in the set command. Finally, specify the desired baud rate for the modem port.
Step 3 Issue the init command at the TCS hub prompt, as shown below:
Again, as in Step 2 above, specify the switch card having the non-matching baud rate. This command initializes the modem port on the switch card with the specified baud rate .
Figure 5-2 in the chapter entitled "Installing Additional Components" illustrates the console/ modem assembly for a switch card. This assembly is inserted in the access (rear) side of the LS2020 chassis opposite a corresponding switch card. This assembly provides the means for attaching a terminal or a modem to your LS2020 switch.
To attach the terminal cable to the console port and to match the terminal and the console port baud rates, perform the following procedure:
The switch card slots in the front of the LS2020 chassis are labeled A and B, as are the corresponding slots for the console/modem assembly bulkhead(s) in the rear of the LS2020 chassis. If the primary TCS hub is on switch card A, connect the terminal cable to the console port of the bulkhead in rear slot A; similarly, if the primary TCS hub is on switch card B, connect the terminal cable to the console port of the bulkhead in rear slot B.
Note If your LS2020 chassis contains two switch cards, connect the terminal cable to the console port on the console/modem assembly for the switch card with the primary TCS hub. To identify this card, examine the green TCS SEL LED on each switch card. The card with the TCS SEL LED lit is the primary TCS hub.
Step 2 Press the Return key on the terminal keyboard.
If the TCS hub<<A or B>> prompt appears, or if some other prompt appears (see the Note below), after you press the Return, the prompt signifies agreement between the terminal baud rate and the console port baud rate and that the terminal is properly attached.
Note If the baud rates match, the system may respond with other than the TCS hub<<A or B>> prompt, depending on the card to which a connection exists. For example, if you had previously established a connection to an NP card via the TCS connect command, the system would respond with the bash (#) prompt, rather than the TCS hub<<A or B>> prompt. The appearance of any valid system prompt on the terminal screen after Return key activation signifies baud rate agreement.
When the system verifies itself as being responsive (through the return of an appropriate prompt), you can then make the terminal fully operational in your LS2020 environment by connecting it to the NP. To do so, proceed directly to the section below entitled "Connecting the Terminal to the NP."
However, if the system does not respond at all, or if screen output is garbled after you press the Return key, one of the following conditions may pertain:
In this case, you must attempt to achieve a baud rate match by continuing with Step 4 below.
In this case, proceed with Step 3 below.
Step 3 Issue the character sequence `. (back quote plus dot, that is, left single quote plus period) at the terminal keyboard and press the Return key. This action breaks the connection which may exist between the switch card and any non-operational or missing card.
If a valid system prompt does not appear following Return key activation, a baud rate mismatch still exists and you must continue with Step 4.
Step 4 For baud rate matching purposes, your LS2020 chassis must be equipped with at least one switch card and a terminal.
Set the terminal to a new baud rate, using the order of precedence defined for the console port in the section above entitled "Setting Console/Modem Baud Rates through TCS Hub Commands."
Step 5 Press the Return key on the terminal.
Step 6 If the baud rates match after you press the Return key, the TCS hub prompt is displayed, indicating that the terminal is properly attached.
Proceed to the section below entitled "Connecting the Terminal to the NP."
However, if the TCS hub prompt is not displayed, you must repeat Step 4 and Step 5 until a match with one of the defined baud rates is achieved.
If the terminal does NOT support one of the defined console port baud rates, proceed with Step 7 below.
If you cycle through all the possible console baud rates without achieving a match, an error condition exists. In this case, contact your Cisco Systems customer support representative.
Step 7 For baud rate selection, this step requires that your LS2020 be equipped with a modem attached to the same switch as the terminal and that you have the ability to dial into the LS2020 chassis.
If you can dial into the LS2020 chassis, do so. Then continue with Step 8 below.
If you are unable to dial into the chassis, skip to Step 10 below.
Step 8 Use the TCS hub set <switch slot> console baudrate <rate> command to set the baud rate of the console port to agree with that of the terminal you are attempting to attach.
Step 9 Reset the applicable switch card.
This action reinitializes the console port to the baud rate selected in Step 8 above.
Proceed to the section below entitled "Connecting the Terminal to the NP."
Step 10 For baud rate selection, this step requires that your LS2020 chassis be equipped with two switch cards. It also assumes that you can communicate with the switch card that currently needs no baud rate adjustment.
Dial into this card via its modem port or use the terminal attached to its console port to set the baud rate, as instructed in Step 11 below.
However, if your LS2020 chassis does NOT contain redundant switch cards, or if neither switch card is accessible via its console or modem port, an error condition exists. In this case, contact your Cisco Systems customer support representative.
Step 11 Use the TCS hub set <"other" switch slot> console baudrate <rate> command to set the console port baud rate for the "other" switch card to agree with the baud rate of the terminal you are attempting to attach.
Step 12 Reset the "other" switch card manipulated in Step 11 above.
This action reinitializes the console port to the baud rate selected in Step 11 above.
Proceed to the section below entitled "Connecting the Terminal to the NP."
Note This procedure assumes that you have already attached a terminal to the Release 2 switch card, as described in the preceding section entitled "Attaching a Terminal and Matching the Baud Rate ."
To connect a terminal to the NP in your LS2020 switch, perform the procedure below. For simplicity, this procedure assumes that you are using the NP in slot 1.
Step 2 Issue the following command at the TCS hub prompt to connect to the NP that you want to configure:
Step 3 When you connect to the NP, part or all of the following countdown sequence is displayed on your screen. Do not press the Return key; allow the boot sequence to continue.
The screen displays for the boot sequence then continue as shown in Step 1 in the section "Entering Configuration Data" later in this chapter. However, before proceeding with the entry of required configuration data, note the following special consideration about running configuration scripts.
When you enter configuration data, two scripts are invoked automatically that prompt you for basic configuration information (see bullets below). If you err in entering information in response to script prompts, you can run the scripts again separately. To do so, enter the name of the script you want to run at the bash# (root) prompt or the single-user ($) prompt.
When you run these scripts from the command line, they behave very much as they do in the scripted configuration procedure. However, one difference of note is that the setsnmpconfig command checks for the presence of configuration files. (Normally, these files are not present during a typical installation of a new LS2020 switch). If the system finds such files, it asks if you want to continue, as shown below:
| Caution If you answer y (yes) to this query, the system overwrites the existing configuration files for this particular LS2020 node, effectively deleting the files. |
If configuration files are present and you choose not to overwrite them, the setsnmpconfig script cannot continue. Instead, the script exits and returns you to the command line.
If configuration files are not present, or if they are present and you choose to overwrite them, a script prompts you to enter network configuration information, as outlined in the following section, "Entering Configuration Data."
In this procedure, a script prompts you to enter basic LS2020 configuration information. In performing this procedure, it is assumed that you have already initiated the boot sequence, as previously described in the section "Connecting the Terminal to the NP."
Note If a problem occurs with the LS2020 hard disk or the platform software, an error message is displayed in lieu of the system output shown in Step 1 below. In this case, refer to the LightStream 2020 Network Operations Guide for instructions about reloading the LS2020 platform software.
Step 2 Enter appropriate time and date information, as prompted by the system:
(The second Enter date prompt confirms the initial date entry.)
Note If your LS2020 switch contains two NPs, ensure that their respective clocks agree to within 1 minute. If the clocks differ by more than 1 minute, the software that synchronizes files between the two NPs may not operate properly.IR EFOBJ:822
Step 3 Enter passwords for the four default login accounts for the LS2020 switch. For each account, enter y, then enter the password twice, as shown below:
Step 4 Enter the network management configuration information for the LS2020 switch, as requested in the following configuration script. (Note that the Host Name and the IP addresses shown in bold typeface in the script below are for illustrative purposes only; you must supply an actual name and real IP addresses in these fields.)
Note For an LS2020 switch with two NPs, you must perform this procedure twice—once for each NP. You must enter identical information for each NP. Do not reverse the active and secondary IP addresses on the second NP; these addresses are assigned to the entire chassis, not to individual NPs. If you do not enter the same information for both NPs, your LS2020 switch will not work.
If you answer Y to this query, proceed to Step 5. Otherwise, continue with the configuration script as follows:
If you confirm that the configuration data you have entered in this step is correct by responding Y to this query, the script continues with the trunk port configuration query below.
On the other hand, if you wish to change any configuration data, answer "N" at the chassis and network processor information query and repeat this step in its entirety. You will be prompted by the configuration script to re-enter all the applicable network management information for your LS2020 switch.
Similarly, if you respond N to the above trunk port configuration query, the system reports that it is creating a minimum configuration database and that you have completed the basic configuration procedure.
If you respond "Y" to the trunk port configuration query, proceed with Step 6 below.
Step 5 If your LS2020 switch contains a redundant network processor, continue with the configuration script, as follows:
Does the chassis contain redundant network processors (Y/N)? [N] Y
Configure the Chassis Secondary IP address (for use by a network processor while acting as backup). This address should be an address on the subnetwork connecting all network processors in your network.
Chassis Secondary IP Address [a.b.c.d]: 192.1.1.12
Your system may be attached to an external Ethernet LAN by means of the on-board Ethernet LAN interface on the network processors.
In a redundant configuration with two network processors, if the network processors are each attached to an external Ethernet LAN by means of the on-board Ethernet LAN interfaces, the two network processors should each be attached to the same Ethernet LAN.
If the network processors are attached to an Ethernet LAN, you will be asked to provide the IP address and IP subnet mask of the network processors' on-board Ethernet LAN interface.
Are the two network processors attached to an Ethernet LAN (Y/N)? [N] Y
In a redundant configuration with two network processors, the primary (active) network processor provides the logical connection to the attached Ethernet LAN. Thus you will be asked to specify only one IP address and mask.
Configure the IP address for the network processors' Ethernet LAN interface.
Network Processor Ethernet IP Address [a.b.c.d]: 197.112.23.12
Configure the IP subnet mask for the network processors' Ethernet LAN interface.
Network Processor Ethernet IP Mask [a.b.c.d]: 255.255.255.0
Is there an IP router on the attached Ethernet LAN (Y/N)? [N] Y
Configure the Default IP router for the network processors' Ethernet LAN interface.
Network Processor Ethernet Default IP Router [a.b.c.d]: 197.112.23.1
Chassis Primary (Active) IP Address: 192.1.1.11
Chassis Secondary IP Address: 192.1.1.12
Chassis Subnet Mask: 255.255.255.0
Network Processor Ethernet IP Address: 197.112.23.12
Network Processor Ethernet IP Mask: 255.255.255.0
Network Processor Default IP Router: 197.112.23.1
Chassis configuration contains 2 redundant network processors.
Network processors' on-board Ethernet LAN interfaces are attached to an external Ethernet LAN.
Is the chassis and network processor information correct? (Y/N) [Y] Y
If you confirm that the configuration data you have entered in this step is correct by responding Y to this query, the script continues with the trunk port configuration query below.
On the other hand, if you wish to change any configuration data, answer "N" at the chassis and network processor information query and repeat this step in its entirety. You will be prompted by the configuration script to re-enter all the applicable network management information for your LS2020 switch.
Configure trunk port information (Y/N) [N] N
Creating minimum configuration database...done.
Similarly, if you respond N to the above trunk port configuration query, the system reports that it is creating a minimum configuration database and that you have completed the basic configuration procedure.
However, if you respond Y to the trunk port configuration query, proceed with Step 6 below.
Step 6 If your LS2020 switch is not directly attached to a LAN to which the NMS is also attached, you must configure a trunk so that SNMP configuration traffic can flow between the new LS2020 switch, the LS2020 network at large, and the LS2020 switch attached to the NMS. In operational terms, the trunk port will be used to load a full configuration over the LS2020 network.
However, for the sake of example, a trunk port for a low-speed card has been selected to demonstrate the trunk port configuration procedure. In this particular case, proceed as directed by the following configuration script:
As with chassis information, if you answer N to the port confirmation prompt, you will be prompted to re-enter all the trunk port information, beginning with the "Trunk Card Type."
If you answer Y, you will be queried if you want to configure an additional trunk, as shown below:
If you respond Y to this query, repeat this procedure to configure additional trunk ports.
If you respond N to this query, the system responds with the following message:
Creating minimum configuration database...done.
A trunk configuration CLI script has been written to /tmp/trunkconfig.cli
The message means that the system has created a minimum LS2020 configuration. It also signifies that the system is loading the line cards, starting the LS2020 platform software, and starting the neighborhood discovery process.
At this point, the login prompt appears. You can then continue with Step 7.
Step 7 If you have previously configured trunk port information as part of the basic configuration procedure, you must apply that information to the platform software.
Note To apply trunk port information to the platform software, you must first wait for the line cards (which incorporate the trunk ports you need to configure) to come up. A line card is signaled as being up when the NDD_3 trap for that card appears on the console, as shown in the example below.
(OPER) NDD_3 at 06/26/95 10:56:04 EDT (06/26/95 14:54:04 GMT)
Line Card ls2020:5 (MS-TR) up.
Next, log in to the system and start the CLI using the oper or npadmin account, as shown in the example below:
When you log into the oper or npadmin account, the CLI starts automatically, first presenting the CLI banner on the console and then the CLI prompt, as shown in the example below:
cli: (ls_main) compiled Jul 26 1995 @ 03:45:21
Copyright 1995. Cisco Systems, Inc. All Rights Reserved.
When the CLI prompt appears, enter the CLI protected mode, as shown below:
Enter Password: <password> Return
Next, invoke the CLI configuration trunk script using the source command, as shown below:
*cli> source "/tmp/trunkconfig.cli"
This command applies the trunk configuration to the trunk ports you have configured. Note that additional traps may be generated at this time to signal the changes in the status of the trunk ports. Such trap messages are normal.
Step 8 If you are installing a new LS2020 switch with two NPs, return to the earlier section "Connecting the Terminal to the NP." Repeat the configuration procedures from that point to configure the second NP for your LS2020 switch.
Upon completion of the basic configuration procedures for the NP(s) in your LS2020 chassis, continue as described in the following section, "How to Proceed."
This section describes actions you should take after installing a new LS2020 switch.
To ensure that the newly installed LS2020 switch is working properly, run the hardware diagnostics described in the LightStream 2020 Hardware Reference & Troubleshooting Guide.
Keep a maintenance log for each LS2020 switch in your network. At a minimum, you should record the following information:
If the current EEPROMs or the midplane are replaced, you will need to enter the chassis ID and modem information into the EEPROMs on the new midplane. See the LightStream 2020 Hardware Reference & Troubleshooting Guide for instructions on finding the chassis ID and modem information.
You are also advised to record any unusual LS2020 behavior. The maintenance log can be highly useful in identifying and correcting chronic or intermittent LS2020 operational problems.
You must install the CLI, the LS-Monitor, the LS-Configurator, the LS-Topology Map, and the private MIB database on the NMS that you will be using to manage your LS2020 network. The chapter "Installing StreamView Software" presents the procedures for installing this network management software.
The chapter "LightStream 2020 Setup Procedures" presents procedures and options that enable you to tailor your network environment to your particular operating requirements. For example, you can enable the security mechanism that prevents unauthorized network access. Also, you can change operational parameters, such as the default SNMP community name(s) and the default trap delivery address(es).
You should read the chapter "LightStream 2020 Setup Procedures"and perform any applicable procedures therein before activating your LS2020 switch in the network.
The StreamView LS2020 configurator is used to create a global configuration database for your LS2020 network and to load appropriate configuration information into each LS2020 switch in the network.
For detailed information about these high-level procedures, see the LightStream 2020 Configuration Guide.
By default, LS2020 chassis (platform) software is installed at the factory on the hard disk prior to shipment of the unit to a customer site. However, if you come into possession of distribution diskettes for a new LS2020 software release and you are concerned about how carefully they may be handled and stored, you should back them up before proceeding with any new software installation.
In the following procedures, it is assumed that you have access to a PC running DOS 5.0 (or later) and which supports at least one 1.44 Mb floppy disk drive. It is also assumed that you have a supply of at least 15 blank, DOS-formatted 1.44 Mb diskettes.
Note Using the diskcopy /v command in this procedure, you can verify the correctness of the copy operation. You can also use the diskcomp command to verify the copy operation. Refer to your DOS documentation for additional information about these commands. Do not use the dir command to display the names of files on the distribution diskettes. There is no FAT (DOS file allocation table) on LS2020 distribution diskettes; thus, there can be no FAT on backup diskettes. If you enter dir a: or dir b: in an attempt to display distribution diskette files, DOS responds with a read error message.
To back up each LS2020 software distribution diskette, perform the following steps:
Step 2 Insert a blank, formatted (destination) diskette in drive B.
Step 3 At the DOS prompt, enter the following command:
Step 4 DOS then copies the data from drive A to the backup diskette in drive B.
Step 5 At the conclusion of the first copy operation, DOS asks if you want to perform an additional copy operation.
Step 6 Press Y and insert the next distribution (source) diskette into drive A.
Step 7 Continue copy operations until all the distribution diskettes are backed up.
To copy each LS2020 software distribution diskette, perform the following steps:
Step 2 At the DOS prompt, enter the following command:
Step 3 DOS reads the contents of the first source diskette into memory. When DOS prompts you to do so, remove the first distribution diskette and insert a blank, formatted (destination) diskette into floppy drive A.
Step 4 DOS copies the data from memory onto the backup (destination) diskette. When DOS prompts you to do so, remove the first backup diskette and insert the next distribution diskette in the series into floppy disk drive A.
Step 5 Alternate Step 3 and Step 4 in response to DOS prompts until you have copied the entire set of distribution diskettes.
