Monitoring a LightStream 2020 Switch

Monitoring a LightStream 2020 Switch

This chapter tells you how to determine the status of a LightStream 2020 multiservice ATM switch (LS2020 switch) and its components. It shows command examples and explains how you can obtain additional information about the LS2020 components and subsystems. It includes the monitoring procedures for the LS2020 monitor, the LS2020 topology map, and the CLI.

Introduction to Monitoring

Three tools are available for monitoring the LS2020 switch: the LS2020 monitor program, the LS2020 topology map, and the CLI. The LS2020 monitor and topology map programs are GUI-based; the CLI is not. In the monitor program, you click on components to display information about them. In the topology map program, you click on components to display a map that represents the actual topology of the LS2020 network. In the CLI, you use various attribute agruments of the show card command to display the value of specified parameters. When you issue a show command, the switch retrieves the requested information from the MIB. You may see a collection of MIB attributes displayed or you may see only a single attribute. You can monitor the following LS2020 components and subsystems:

For a description of trap monitoring, see the LS2020 Traps Reference Manual.

Using the LS2020 Monitor

The LS2020 monitor provides a graphical display of individual LS2020 switches, cards, and ports. When you start the monitor application, the display shows the front of an LS2020 switch with bulkheads for the cards as they appear in the actual switch. Information pertinent to the switch displays above the bulkheads.

This section explains how to access the monitor to display switches, cards, and ports. The monitor application uses color to indicate the status of various entities; therefore, you must have a color monitor to make effective use of the monitor software.

To start the LS2020 monitor, follow these steps:

Step 1 Log in to the NMS workstation.

Step 2 Invoke the LS2020 monitor by selecting it from the HP OpenView menu or by entering the following command at the system prompt:

where


<chassisname> is the name of the node you want to view.


A display similar to the one shown in Figure 4-1 is shown. It shows the front view of the LS2020 chassis, its components, and their status. The name that appears on the top of the LS2020 Monitor Chassis View window reflects the name of the chassis you selected to monitor. The front and rear displays are logical representations of the LS2020 chassis. They are not physical representations that you can modify.



Figure 4-1: Example of an LS2020 Monitor Chassis View




Selecting a Menu Option

To select a menu option from the top menu bar on the monitor display (see Figure 4-1), follow these steps:

Step 1 Point and click on the menu option (for example, File or Slot) and hold the button down.

Step 2 Slide the mouse button down to display the available menu options.

Step 3 Release the button on the option to select it.

Table 4-1 lists the possible options. All menu options may not be available at all times. Availability depends on the display in the window. Available options are highlighted.

Step 4 To close a monitor display, click in the Close box in the bar at the top of the window.

Selecting a Monitor Display Object

Step 1 To select an object in the monitor display, click on it with the left mouse button. The object appears highlighted. Figure 4-2, for example, shows an LS2020 switch with a packet line card (PLC) selected. Selectable objects in the monitor display are cards, thermometer icons, bulkhead screws, and the LightStream logo.

Step 2 To see more information for a particular object in the display, double-click on the object with the left mouse button or select the object with a single click of the left mouse button and click on the Open Selected Object option from the Slot pulldown menu.


Figure 4-2: Example of LS2020 Monitor Chassis View with Selected Card




Monitor Dialog Boxes

When you select an object, a dialog box is displayed.The LS2020 monitor application provides eight kinds of dialog box. There is no particular order in which you should invoke these windows. The dialog box you invoke depends on what type of information you want to display or what task you want to perform. The dialog boxes are as follows:

The next sections tell you how to open a dialog box and summarize the information that each box contains.

Note Information in the display box gets updated every 2 minutes--the default polling period. The polling period cannot be changed once the monitor program begins.

LS2020 Monitor Card Window

To open a new window for an NP or a line card, click on the card, and then click on the Open Selected Object option from the Slot pulldown menu. (Selecting this menu option is equivalent to double-clicking on the object.) A Monitor Card window is displayed (see Figure 4-3).


Figure 4-3: LS2020 Monitor Card Window



The Card window displays card and port status information and per-port statistics. You can use the vertical scroll bar to view all the relevant port information for the selected card. This window is capable of being displayed, but not edited or modified. However, the monitor application polls the target node for a fixed set of MIB objects and updates the dialog box approximately every 2 minutes.

Chassis Status Window

To view chassis information, double-click on the LS2020 logo in the upper-right corner of the monitor display (see Figure 4-1). A Monitor Chassis window is displayed (see Figure 4-4).


Figure 4-4: LS2020 Monitor Chassis Status Window



The Chassis Status window displays chassis-level information, such as the chassis name and chassis identification number. It also contains the duration of the monitor session, the time of the last contact with the node, and the time that has elapsed since the last contact.

CLI View Window

To open the CLI view window, click on the snmp cli option from the General pulldown menu. The CLI View window is displayed (see Figure 4-5).


Figure 4-5: LS2020 Monitor CLI View Window



From the CLI view window, you can issue CLI commands to monitor and configure the node. For more information about the CLI, see "Command Line Interface" chapter or the LightStream 2020 CLI Reference Manual.

Help Topics Window

To access the Help Topics window, click on the On help option from the Help pulldown menu. The Help Topics window is displayed (see Figure 4-6).


Figure 4-6: Help Topics Window



An index of help topics is listed. The help topics appear in alphabetical order. After you select the topic you want help on, click on OK or double-click on the topic itself. You can use the vertical scroll bar to view all the available help text for the selected topic.

Nettime Status Window

To open a new window for Nettime clock status information, double-click on an SWC2 bulkhead (a bulkhead with a BITS OK LED). A Nettime Status window is displayed (see Figure 4-7).

Note The Nettime service is not supported on a chassis that contains an SWC1 card.

Figure 4-7: LS2020 Monitor Nettime Status Window



The Nettime service for a target switch uses a switch card (SWC2) to distribute a single reference clock to all the line cards in a given chassis.

The available sources for the reference clock are

You can configure up to 10 reference clock sources for the target chassis, listed in order of preference. If the preferred source fails, Nettime automatically switches to the next most preferred source that is currently available. The monitor application polls the target node for the approriate Nettime MIB objects and displays the results.

If a switch failure occurs in a chassis that contains a redundant switch, Nettime automatically uses the backup switch card to distribute the reference clock to the line cards on that chassis.

New Monitor Process Target Window

To open a new window to monitor a chassis, click on the Open New Chassis option from the File pulldown menu. The New Monitor Process Target window is displayed (Figure 4-8).


Figure 4-8: New Monitor Process Target Window



The system prompts you for the name of the new chassis you want to monitor. After you enter the name of the new chassis, a new monitor Chassis View window (see Figure 4-1) is displayed. You can continue to monitor the old chassis in the original window.

Temperature Window

To view temperature information, double-click on the thermometer icon on the line card bulkhead display (see Figure 4-1). A screen like the one shown in Figure 4-9 is displayed.


Figure 4-9: LS2020 Monitor Temperature Window



The Temperature window shows a summary view of the temperature values of the corresponding card. It also displays the warning and shutdown points for each card. The thermometer icons turn red when the card exceeds pre-defined temperature limits.The monitor application polls the target node for the appropriate MIB objects and displays the results.

Version Window

To see the software version of the monitor application that you are using, click on the On Version option from the Help pulldown menu. A screen like the one shown in Figure 4-10 is displayed.


Figure 4-10: LS2020 Monitor Version Window



Interpreting Colors in the LS2020 Monitor Display

The LS2020 monitor application uses color to indicate the status of various objects. This section provides information about the following objects and their corresponding colors:

Bulkhead Paint Bars and Screws

The paint bars in the monitor graphical display of line card bulkheads correspond to the colors that are actually painted on the bulkheads of the cards. Table 4-2 lists the colors that represent the line cards.


Table  4-2: Line Card Bulkhead Paint Bar Colors
Line Card Color1
Network processor card (NPC) Red
Packet line card (PLC) Orange
Cell line card (CLC) Purple
Low-speed line card (LSC) Dark blue
Medium-speed line card (MSC) Light blue
Switch card (SWC) Dark green

1 The color of the card does not change.

When a card goes down (ceases to operate), the bulkhead screw for that card turns red. If the card is up, the bulkhead screw is white.

LEDs

If an LED on the monitor display is shown as black, it is unlit. If an LED is shown as white, the monitor does not know its status either because the status is changing too rapidly or because the monitor does not have MIB support. For example, an LED on an access card is shown as white . Table 4-3 lists LEDs, their colors, and their meanings.


Table  4-3: LED Colors and Their Meanings

LED Color Meaning
FLT Amber The card has failed POST.
RDY Green The card has passed POST.
VCC: 5-volt power Green Voltage is within range.
Red Voltage is high.
Dark green Voltage is low.
Black Voltage is less than 4 volts.
TCS: test and control system Green Voltage is within range.
Red Voltage is high.
Dark green Voltage is low
Black Voltage is less than 4 volts.
TCS SEL Green The switch card (SWC2) is the master TCS hub (the TCS HUB doing the polling).1
BITS OK Green2 Indicates the following:

  • External BITS T1 reference clock (plugged into the BITS interface) is accurate.

  • The data is phase-locked.

  • There are no alarm indications.

If the previous conditions are not true, the LED is dark.

TX White Unsupported.
RX White Unsupported.
LN FLT Amber At least one port on the card is configured as up (enabled), but is down (ceases to operate) or experiencing high error rates.
LNS OK Green At least one port on the card is configured up (enabled) and is operationally up with no errors.

1 In a system with a reduncant switch card (SWC2), this LED is lit for the master (primary) TCS HUB card and is unlit for the slave (secondary) TCS HUB card.
2 For this release, the BITS OK LED displays white.

Nettime Icon

The Nettime status icon appears directly to the right of the B Power Supply status icon. Table 4-4 lists the icon colors that indicate the status of the Nettime service.


Table  4-4: Nettime Status Icon Colors and Their Meanings

Icon Color Meaning
Purple Uninitialized. The status is unknown (the first poll of the node has not occurred yet).
Black Nettime is unavailable on this chassis (usually because the chassis contains an SWC1 card or SNMP poll failed).
Green Nettime is up and operating normally.
Yellow Nettime is up, but the configured clock value is not the same as the active clock value and the configured clock status is down.
Orange Nettime is up, but the active clock value does not match the configured clock value, and the configured clock status is up. This is slightly more serious that the yellow state because it may require more immediate operator intervention to bring the configured clock back to the "up" state.
Red Nettime is up, but the active clock is not one of the clocks on the configured priority list or Nettime is in illegal state.

Power Supply Icon

There are two icons in the summary area (logo area) that indicate the status of the two power supplies (see Figure 4-1). Table 4-5 lists the icon colors that indicate the status of the power supply.


Table  4-5: Power Supply Icon Colors and Their Meanings
Icon Color Meaning
Purple Uninitialized. The status is unknown (the first poll of the node has not occurred yet).
Black Power supply is missing.
Green Power supply is operational.
Red Power supply has failed.

Thermometer Icons

Thermometer icons are displayed on the bulkheads show on the LS2020 Monitor Chassis View screen (see Figure 4-1). Each icon shows various values for the card with which it is associated. These values include recorded temperature, warning point, and shutdown point. The values are also recorded in the MIB. Table 4-6 lists the colors used in the thermometer icon and indicates the significance of each.


Table  4-6: Thermometer Icon Colors and Their Meanings
Icon Color Meaning
Blue Temperature is normal.
Yellow-orange1  At least one temperature has reached it warning point.
Red-orange1 At least one temperature has reached its shutdown point.

1 The yellow and red icons each have an orange band around them to emphasize the abnormal condition.

Using the LS2020 Topology Map

The LS2020 topology map application displays a map that represents the actual topology of an LS2020 network. The map is a set of related objects, symbols, and submaps that provide a graphical and hierarchical presentation of the network.

The LS2020 topology map application runs on HP OpenView. If you are not familiar with the HP OpenView Windows product, see the HP OpenView User's Guide. When you start HP OpenView, the LS2020 Topology map application is automatically invoked. Once you start the application, it builds the current LS2020 submap and then periodically polls each LS2020 node for status information. When creating a new HP OpenView map, you can turn off the LS2020 topology function. You must have a color monitor to use the LS2020 topology map application.

The LS2020 topology map provides

Once the LS2020 submap is created, you can modify it by

You can also show multiple trunk connections, which are represented by meta-connection symbols. The symbol for a meta-connection is <n>, where n is the number of connections being represented (see Figure 4-12).

Building a Topology

As previously mentioned, once you start HP OpenView, it can create any number of maps, and each map is able to be configured to build an LS2020 topology. However, you do not view a map directly. You view the submaps that make up the map. A submap is a particular view of the network environment. Each submap displays a different view of your map. The application creates a Root submap for each LS2020 map. The Root submap provides a standard, top-level submap for every network map.

Figure 4-11 shows an example of a Root submap. In this figure, the Root submap contains two symbols: one that represents the Internet and another that represents an LS2020 network.


Figure 4-11: Example of a Root Submap

When you open a map, you actually view submaps of the map. To open the LS2020 submap, double-click on the LightStream symbol. Figure 4-12 shows a sample LS2020 topology submap.

In this example, the trunk between the ls-alpha2 and ls-alpha-np nodes actually represents two trunks, as indicated by the meta-connection symbol <2>.


Figure 4-12: Example of an LS2020 Topology Submap

Displaying Meta-Connections

When a meta-connection is first drawn, its symbol is not displayed. To display a meta-connection symbol (see Figure 4-13), follow these steps:

Step 1 Click the right mouse button on the trunk.

Step 2 Select Describe/Modify Symbol... from the option menu.

Step 3 Select the Display Label.

The next sections describe how to modify the LS2020 submap and view its meta-connection submap.


Figure 4-13: Meta-connection Submap

Creating LS2020 Domains

LightStream domains (logical groups of nodes) can consist of any number of LS2020 nodes. All trunk connections between selected nodes and nonselected nodes are redrawn between the LS2020 domain and the non-selected nodes. Any meta-connections between an LS2020 domain icon and either another LS2020 domain or a node show the two nodes that are connected. When you show an exploded view of an LS2020 domain icon, the nodes that make up the domain and any trunk connections between these nodes are displayed.

To create an LS2020 domain, follow these steps:

Step 1 Select the LS2020 nodes that you want grouped together.

Step 2 Pull down the LightStream menu from the menu bar, and click on Topology...Build Domain.

The selected nodes are removed from the map and replaced by a single domain icon.


Removing an LS2020 Domain

When you remove a domain from the topology map, the LS2020 nodes that were originally grouped in that domain are redrawn onto the current submap. To remove an LS2020 domain, follow these steps:

Step 1 Select the domain you want to remove.

Step 2 Pull down the LightStream menu from the menu bar, and click on Topology...Remove Domain.

Deleting a Node or Connection

If you want to remove a node or connection from the LS2020 submap, follow these steps:

Step 1 Double-click on the node or trunk that you want to delete.

Step 2 Pull down the Edit pulldown menu on the menu bar, and click on Delete.

When you remove a node or trunk connection from the LS2020 submap, it is rediscovered and placed back on the map. To prevent this from happening, click on Hide on the Edit menu. This option keeps a node or trunk connection from being rediscovered and placed back into the submap.


Displaying Trunk Information

Within the LS2020 submap, a trunk connection is displayed including its interface bandwidth. If you want to get chassis, port, and utilization information about this connection, you click the left mouse button on a trunk. A pop-up dialog box appears and information similar to the following displays (see Figure 4-14).


Figure 4-14: Example of a T

runk Connection

Updating a Topology

The LS2020 Topology Manager periodically queries each LS2020 node for its trunk information to see if new trunks have been added or known trunks have been removed. It also communicates with HP OpenView for any new objects that are discovered. If new objects are found, the LS2020 Topology Manager (LTM) checks to see if the object's SysOid number matches its own.

Changing LS2020 Topology Map Attributes

The LS2020 submap attributes that you can modify are

The next sections provide a brief description of the attributes and the steps for changing them.

Procedure to Change the LS2020 Topology Map Attributes

You can modify these attributes from either the OpenView Root dialog box or the LS2020 Submap dialog box:

Step 1 Pull down the File menu on the menu bar, and click on Describe/Modify Map. The Map Description dialog box appears (see Figure 4-15).


Figure 4-15: Example of Map Description Dialog Box

Step 2 Click on the appropriate entry in the Configurable Applications list.

Step 3 Click on the Configure for this Map button. For example, if you click on the LS2020 Topology Map, the Configuration box appears (see Figure 4-16).


Figure 4-16: Example of Configuration Dialog B

ox

From the Configuration box, you can enable or disable the LS2020 Topology Manager (LTM) and select the attributes that you want to modify, such as status polling interval, timeout for trunk removal, and so on.

LTM Enabled/Disabled

The default is to enable the LS2020 Topology Manager (LTM) when you start HP OpenView.

Status Polling Interval

The LS2020 topology map application polls each LS2020 node periodically for status information (the default polling time is 60 seconds).

Status changes in the network are displayed through changing colors on the network map and writing messages to HP OpenView Alert window.

Status Definitions

Table 4-7 lists the possible status conditions of a node in the network and their meanings. Table 4-8 lists the same information for a trunk connection in the network.


Table  4-7: Node Status Definitions
Status Meaning
Unknown Unable to access the node through SNMP.
Critical One of the following problems has been detected: a chassis ID conflict, a bad power supply, abnormal temperature, or a diagnostic error on a card.
Major One or more cards within the node reported a down operational status.
Marginal One of the following problems on an edge port has been detected: congestion, high error rate, large amount of discarded traffic, or attempt to use an improperly configured PVC. If any of these problems is detected, a message appears in the HP OpenView Events window. Note that for Release 2.1 edge port monitoring is turned off.
Normal No known problems detected.
Unmanaged The user has configured the node to be unmanaged.

Table  4-8: Trunk Connection Status Definitions
Status Meaning
Critical The ifOperStatus reported down for either port in the connection, or the trunk is no longer being discovered in the GID table.
Testing The ifOperStatus reported testing for either port in the connection.
Normal No known problems detected.
Major One of the following problems on either of the ports on the trunk connection has been detected: high number of packets being discarded, high trunk utilization, high error rate, or attempt to use an improperly configured PVC. If any of these problems are detected, a message appears in the HP OpenView Events window.
Warning One of the following problems on either of the ports on the trunk connection has been detected: high number of packets with unknown protocols being received or the output queue length is excessively high.
Unmanaged The user has configured the trunk to be unmanaged.

Unknown

Unable to get port information through SNMP.

Timeout for Trunk Removal

The default for the timeout for trunk removal attribute is 300 seconds.

Rules

The LS2020 topology map application collects information for each interface to determine the condition of the LS2020 network. There are rule definitions that apply to the data collected. For example, the default value for the percent inbound packets being discarded is 15 percent. If the percent of packets being discarded exceeds either the default value or the value you set, a message gets logged to the HP OpenView Alert window. You can change the rate of the default value according to your network needs. Table 4-9 lists the rules and their default values that are applied to the data collected.


Table  4-9: Rule Definitions
Rule Default Value
Percent inbound packets being discarded 15%
Percent inbound packets with unknown protocol 2%
Percent inbound packets containing errors 2%
Percent outbound packets being discarded 15%
Percent outbound packets containing errors 2%
High output queue length 10

Marginal/Major Status Timeout

Marginal status indications for nodes and major status indications for connections indicate potential network integrity problems. Once a problem is discovered, such as a large number of packets being discarded, the appropriate status is set. The status remains in effect until a time period (the default is 5 minutes) elapses without the problem being discovered. To change the default, select the File...Describe/Modify menu item.

Using the CLI to Monitor Hardware Components

This section provides the steps for monitoring the hardware components of an LS2020 switch:

Monitoring a Chassis

To monitor the chassis, follow these steps. The information that displays applies to the LS2020 switch.

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

cli> show snmp

If you need instructions on changing the target switch, see the section on "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface."

Step 2 Enter the following at the cli> prompt:

cli> show chassis <parameter>

Monitoring Cards

You can monitor network processor (NP) cards, edge cards, trunk cards, and switch cards. You select the card you want to monitor by specifying its card number (slot number).To determine a card's slot number, you can look at the front of the system to see the numbered slots (see Figure 4-1). When you specify a card, you also get information on its associated access card. To monitor the cards in the LS2020 switch, follow these steps.

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

If you need instructions on changing the target switch, see the section on "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface."


Step 2 Enter the following at the cli> prompt:

where


<card #> is the slot in which the card you want to monitor is located.
1 -- 2 for NP cards
2 -- 10 for line cards
switcha or switchb for switch cards


<parameter> is all (default)
name (no information available for switch cards)
processid
status
version
peak-cell-rate
hardware
ports (no information available for NP or switch cards)


The results of this command vary, depending on the type of card in the slot. If you enter any parameter except the all parameter, a subset of the attributes is displayed.


When you enter show card 5 all, information similar to the following (for a medium-speed card) is displayed:

cli> show card 5 all Card Name: emtb7.5_ms-t Card PID: 31 Operational Status: Up Administrative Status: Up Configuration Register: Up Maximum Number of VCs: 800 LC Software Version: Version: 1.3.20.1 Compiled cp_ms1.aout: compiled Oct 16 1995 @ 09:51:16 in /u2/mszczesn/ls2_1_1/cmd/ms1_cp LCC Software Version: LCC (Version 1.000 of Oct 16 1995) Card Type: MS Trunk Top Temperature: 72 F (22 C) Bottom Temperature: 70 F (21 C) TCS Voltage: 4.931 volts VCC Voltage: 4.980 volts VEE Voltage: 2.499 volts Access Card Region 1 Temperature: 68 F (20 C) Access Card Region 2 Temperature: 71 F (21 C) Port Protocol Name Admin Stat Oper Stat ---- -------- ---- ---------- --------- 5.0 MS Trunk tb7.5.0-tr-t Up Up 5.1 MS Trunk tb7.5.1-tr-t Up Up cli>

Monitoring DSU/CSU Statistics

The csumon tool, available from the bash shell, lets you monitor the DSU/CSU for the following:

In addition, you can use csumon to issue commands to an external DSU/CSU attached to a low-speed interface.

Monitoring the DSU/CSU on a Low-Speed Line Card

You can obtain CSU statistics by connecting to an external data service unit/channel service unit (DSU/CSU) from an LS2020 switch through a serial line. This provides a terminal to the DSU/CSU. You use its own interface to set up and monitor the DSU/CSU. (See the documentation for the DSU/CSU for details.)

Step 1 Connect the LS2020 switch to the external DSU/CSU by connecting an EIA/TIA-232 serial cable from the control port on the fantail to the CSU craft (or console) port.

Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232 and RS449 before their acceptance as standards by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

Step 2 To access the bash shell prompt, log in as root or fldsup on the LS2020 switch to which the DSU/CSU you want to monitor is attached.

Step 3 Test the connection by using the following command:

where


<.card.port#> is The target switch card and port number in the LS2020 switch, entered in .card.port format (card 2 - 10; port 0 -- 7)


Note You must use the leading "." in the card and port entry shown above.

Figure 4-17 shows a screen displaying the kind of information you might see in a DSU/CSU status display. The display you see may vary, depending on the DSU/CSU you are using.

Note While the statistics are displayed, you can refresh the screen or alter the counter display. See the last line in the previous screen display for instructions on how to do this.

Step 4 Terminate the display by pressing ^C. This returns you to the bash shell prompt.

Step 5 To learn about commands you can issue to the DSU/CSU, consult its documentation. To obtain help on csumon, enter the following command:

Monitoring the DSU/CSU on a Medium-Speed Line Card

The medium-speed line card (MSC) has a built-in DSU/CSU. Use the following steps to monitor and display the DS3 MIB statistics for MSC ports. MSC CSU statistics are available through use of the standard DS3 MIB variables.

Step 1 To access the bash shell prompt, log in as root or fldsup to the LS2020 switch.

Step 2 Enter the following:

where


<.card.port#> is the target switch card and port number in the LS2020 switch, entered in .card.port format (card 2 -- 10; port 0 -- 7).


Note You must use the leading "." in the card and port entry previously shown.

A screen similar to the one in Figure 4-18 is displayed. Although you enter only one port number, information for both ports on the MSC displays.



Figure 4-18: Example Showing csumon Display for a Medium-Speed Line Card



Note While the statistics are displayed, you can refresh the screen or alter the counter display. See the last line in the previous screen display for instructions on how to do this.

The DS3 MIB maintains these counters over a 24-hour period in 15-minute intervals. The Total column in the display includes up to 96 complete intervals. The Current column includes all counts that will make up the next complete interval. The Intrvl column shows the selected complete interval (from 1 to 96), depending on the actual number of complete intervals. The values that change are updated once per second.


Table 4-10 and Table 4-11 list the counters and their definitions.

Using the CLI to Monitor Configuration and Status

This section provides steps for monitoring the configuration and status of the following connections and processes of an LS2020 switch:

Monitoring ATM Connections

To monitor the ATM UNI virtual channel identifiers (VCIs) configured on a particular ATM UNI port, follow these steps. They provide you with information on the individual connections configured on each port. This information is available for ATM UNI ports only.

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

If you need instructions on changing the target switch, see "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface." To get a list of all VCIs configured on a particular ATM UNI port, enter the following at the cli> prompt:


where


<port#> is the number of the port for which information displays. The port number is in card.port format (card is 2 -- 10; port is 0 -- 7).


Step 2 Once you have a list of all ATM-UNI VCIs, you can look at a particular VCI by entering the following at the cli> prompt:

where


<vci#> is the number of the VCI for which information displays.


Figure 4-22 is an example of the display you see when you enter show port 6.0 vci 16.


Figure 4-22: Example Showing the show port 6.0 vci 16 Display

You can also get a list of all the ATM UNI VCIs for the entire chassis by entering the show chassis listvci command.

Monitoring Frame Relay Connections

These steps allow you to monitor individual data link connections configured on Frame Relay ports. These connections are recognized by their data link connection identifiers (DLCIs).

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

If you need instructions on changing the target switch, see "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface." To get a list of all data link connections configured on a particular Frame Relay port, enter the following at the cli> prompt:


where


<port#> is the number of the port for which information displays. The port number is in card.port format (card is 2 -- 10; port is 0 -- 7).


Step 2 Once you have a list of DLCIs, you can look at a particular circuit by entering the following at the cli> prompt:

where


<dlci#> is the DLCI number for which information displays. The DLCI number must be between 16 and 991.


Note  See the LightStream 2020 CLI Reference Manual for information on setting and showing port attributes with the CLI.

Figure 4-23 shows an example of the display you see when you enter show port 10.7 dlci 141.

If you enter any parameter except all, a subset of the attributes shown above is displayed.

Monitoring Processes

These steps let you monitor the status of a particular process. You select the process you want to monitor by entering its number or name.

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

If you need instructions on changing the target switch, see the section on "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface."


Step 2 If you do not know which processes are running, enter the following at the cli> prompt:

This command lists the process identification (pid) numbers and alias names of all processes running on this LS2020 switch. The pid numbers follow the term "Name: lwmaTrapCliAlias," and the alias names follow the term "Value."


The following is an example of the display you see when you enter walksnmp pidName:

Step 3 Choose the processes that you want to monitor from this list.

Step 4 To display the status of a particular process, enter the following at the cli> prompt:

where


{<#> | <alias>} is the number of the process or the alias name of the process from which you want to display status.


[<parameter>] is all (default)

The following is an example of the display you see when you enter show pid 9 all:

cli> show pid 71 all PID Name: rmon PID Alias: RMON PID Up Time: 121 Hr 43 Min 25 Sec PID Administrative Status: Active PID Operation Status: Active PID Trap Level: Info cli>


The same information displays when you enter show pid lcc9. (The lcc9 entry is the alias name for process 9.)

If you enter any parameter except all, a subset of these attributes displays.

Monitoring SNMP Parameters

SNMP operation is controlled by a number of parameters that are set to default values when the system is started. These parameters can be changed through use of the set snmp command. (See the "SNMP Commands" chapter for a discussion of this command.)

To monitor SNMP parameters, enter the show snmp command at the cli> prompt. The following is an example of the display you see when you enter show snmp:

cli> show snmp Community: public HostName: localhost cli>

Monitoring the Test and Control System

The test and control system (TCS) is a fully integrated, yet autonomous, computer system with the LS2020 chassis. There is a TCS microcomputer on each NP, interface, and switch module in an LS2020 chassis. The TCS has a separate communications path from the LS2020 switch.

The main functions of the TCS are to manage low-level operations of each module and to provide access to all modules in the chassis through a local console port, which is supported by the TCS microcomputer on the switch card.

Monitoring TCS

To monitor the values collected by the TCS on a particular card in the chassis, follow these steps. The cards you can monitor are in slots 1 -- 10, switch A (SA), and switch B (SB).

Step 1 Verify that the target switch is correct by entering the following at the cli> prompt:

If you need instructions on changing the target switch, see the section on "Setting the Target Switch for CLI Commands" in the chapter entitled "Command Line Interface."


Step 2 Enter the following at the cli> prompt:

where


<card #> is 1 -- 2 for NPs
