This chapter helps you prepare for first-time startup. Read it before you power up your router.
By preparing for first-time startup, you can take advantage of the full range of configurations available on your routers, including the protocol translation option. You are not required to plan your network before sitting at the console and using the setup command facility for the first time, but you must connect an ASCII terminal to the router's system console port as described in the "Overview" chapter. By separating the planning tasks from the configuration tasks, you can set up the router in one sitting. You can also tailor the router to meet your needs and to fit within a consistent network scheme.
This chapter helps you complete the following tasks:
Use the blank configuration worksheets in the "Blank Worksheets" appendix to record parameter values, according to the information in this chapter. The Global Configuration Worksheet can accommodate global information about a single router. If you plan to install more than one router, make additional copies of the blank worksheet. The Interface Configuration Worksheet can accommodate four interfaces. If you plan to install more than four interfaces on your router, make additional copies of the blank worksheet.
You use these worksheets to help gather and maintain information about your router. The worksheets map to the two-part configuration process of the setup command facility, which is automatically invoked at first-time startup. In the first part of the configuration process, you use the values recorded on the Global Configuration Worksheet to specify global or system-wide parameters. In the second part, you configure each individual interface using the values you recorded on the Interface Configuration Worksheet.
The Global Configuration Worksheet, when properly filled in, contains all the values you need to enter when you configure global parameters with the setup command facility. Remember, the setup command facility is automatically invoked at first-time startup. Preparing the pertinent information before you start up the router enables you to get your system running quickly and uneventfully.
The worksheet lists two levels of information:
The setup command facility does not request system hardware information at first-time startup, but it is useful to write the information on the worksheet to complete your records. The facility does request global parameters at first-time startup.
Figure 2-1 shows the Global Configuration Worksheet. Obtain a copy of the blank Global Configuration Worksheet in the "Blank Worksheets" appendix before continuing. As you proceed through the following descriptions, record your information on it.
Use this section to determine system hardware information and record the information on the Global Configuration Worksheet.
A Default: label marks the factory default and an Action: label marks the action you take to fill in the worksheet.
Several network routers accommodate a wide variety of connectors, appliques, and interface controller cards. The system type is clearly marked on the front of your router. The following system types are available:
Default: None
Action: Circle your system type on the worksheet, or write it in.
The serial number is on the bottom or back panel. This number can help you track your physical inventory.
Default: None
Action: Write your system serial number on the worksheet.
When you order a system, you specify the number and type of interfaces you want the factory to install. The number of interfaces depends on the type of system you have and the number of interface cards installed. Check the back of your router to verify the number of installed interfaces. For help in identifying the installed interfaces, refer to the installation and maintenance guide for your router.
The number of installed interfaces affects the second part of the configuration process. It determines how many Interface Configuration Worksheets you fill in, and what information you need to provide at first-time startup.
Default: None
Action: Write the number of interfaces on the worksheet.
This section contains information about the global parameters that you can configure through the setup command facility. A Default: label marks the factory default, and an Action: label marks the action you take to fill in the worksheet. Use this information to complete the Global Configuration Worksheet.
The host name is the name of your router. The name you specify is used in system prompts and can contain from 1 to 80 uppercase and lowercase alphanumeric characters. The host name is case sensitive. A number can be the first character. Leading spaces are ignored. For example, " 4000F2" is interpreted as "4000F2" (without the space).
Use a name that helps you identify the location of the router, or to whom it is providing routing services. If you will be naming more than one host in your network, devise a consistent naming scheme so that host identification is easy.
Default: Router
Action: Write your host name on the worksheet the way you want it to appear in system prompts.
Your system has two default levels of security: user and privileged. The commands at the user level are a subset of those at the privileged level. Because many privileged commands are used to set operating parameters, you should password-protect these commands to prevent unauthorized use. Users must enter the correct password, called the "enable password," to gain access to the privileged-level commands.
There is no factory default enable password. However, the enable password you set during first-time startup appears as the default the next time you run the setup command facility.
An enable password can contain from 1 to 80 uppercase and lowercase alphanumeric characters, except that the first character cannot be a number. Some spaces are valid password characters; for example, "two words" is valid. Leading spaces are ignored, but trailing spaces are recognized. For example, " woolly" is interpreted as "woolly" (without the space). On the other hand, "woolly " is interpreted as "woolly " (with the space).
For more information about the enable password, refer to the Router Products Configuration Guide or the Router Products Command Reference publication.
Default: None
Action: Write the enable password on the worksheet.
A virtual terminal password can contain from 1 to 80 uppercase and lowercase alphanumeric characters, except that the first character cannot be a number. Some spaces are valid password characters; for example, "two words" is valid. Leading spaces are ignored, but trailing spaces are recognized. For example, " woolly" is interpreted as "woolly" (without the space). On the other hand, "woolly " is interpreted as "woolly " (with the space).
The virtual terminal password is case sensitive. There is no factory default virtual terminal password. However, the virtual terminal password you set during first-time startup appears as the default the next time you run the setup command facility.
Although each virtual terminal line requires a password by default, you can disable password checking to allow line connections without passwords. With this configuration, users are not required to give a password, although one may exist. To disable passwords, use the no login command. Refer to the Router Products Configuration Guide and the Router Products Command Reference for more information on disabling passwords.
Default: None
Action: Write your virtual terminal password on the worksheet. This single password applies to all virtual terminal lines.
The Simple Network Management Protocol (SNMP) is the most widely supported open standard for network management. It provides a means to access and set configuration and run-time parameters of routers and communication servers. SNMP defines a set of functions that can be used to monitor and control network elements.
You configure SNMP on a global basis only; you cannot specify it for individual interfaces.
Default: No
Action: Circle Yes on the worksheet if you want to configure SNMP on a system-wide basis. At first-time startup, this value configures read-only SNMP with a blank password. Circle No if you do not want to run SNMP.
If you configure SNMP, also specify a community string as follows:
mycommunity", "my community", and "mycommunity " are invalid community strings due to the leading, embedded, and trailing spaces, respectively. "ThisIsMyCommunity5" is a valid community string because no spaces exist. The community string is case sensitive. Your router supports the Network Computing Device, Inc. XRemote feature on the Cisco 2500, Cisco 3000 series, and Cisco 4000 series of routers. When an NCD terminal does not include in ROM the fonts used by X applications, you must identify one or more font servers from which the router and the NCD terminal can obtain fonts. You can identify as many XRemote font servers as you need; it is unlikely you will reach the maximum number that the software allows.
You can use the setup command facility at first-time startup to identify one or more XRemote font servers. If you use setup to configure your XRemote font servers, the facility prompts you to enter an IP address for each font server. After first-time startup, you use the xremote tftp host command to configure XRemote font servers.
Default: No
Action: If you want to configure one or more XRemote font servers during first-time startup, circle Yes on the worksheet. If you do not want to configure XRemote font servers on your system or you do not want to configure XRemote font servers using the setup command facility, circle No.
Enter an IP address for each XRemote font server.
For more information about XRemote configuration and management information, refer to the publication Protocol Translation Configuration Guide and Command Reference.
DECnet is a protocol suite developed and supported by Digital Equipment Corporation. The DECnet protocol associates addresses with machines, not interfaces.
A router can have only one DECnet address. DECnet addresses are specified by area number and node number. For example, in DECnet address 53.6, DECnet node 6 is located in area 53.
An area can span many routers, and many areas can be attached to a single cable. If a DECnet host such as a router exists on many cables, its area/node address is the same on all cables. This type of addressing is called DECnet Phase IV addressing.
Default: No
Action: If you plan to use DECnet Phase IV addressing, circle Yes on the worksheet. If you do not want to use DECnet Phase IV, circle No. If you want Phase V addressing, select the Connectionless Network Services (CLNS) protocol (further down on the worksheet) in addition to circling No.
If you plan to use DECnet Phase IV addressing, provide the area number and node number, and indicate whether you want area routing. Write in values for the following:
Default: Yes
Action: If you plan to route IP, circle Yes. If not, circle No.
Select an interior routing protocol for IP. Using the setup command facility, you can specify only one of two interior routing protocols to operate on your system: Interior Gateway Routing Protocol (IGRP) or Routing Information Protocol (RIP). These protocols are mutually exclusive.
IPX is the network protocol used by Novell's NetWare products. Your router supports IPX. For detailed information on IPX, refer to the Router Products Configuration Guide.
Default: No
Action: If you plan to configure IPX, circle Yes. If not, circle No.
Xerox Network Systems (XNS) was originally designed to run over Ethernet. XNS can also be routed over FDDI, Token Ring, and point-to-point serial lines. Your router supports the XNS protocol suite. For detailed information on XNS, refer to the Router Products Configuration Guide.
Default: No
Action: If you plan to configure XNS routing on your system, circle Yes. If not, circle No.
AppleTalk is a network protocol developed by Apple Computer. It is a client-server, or distributed, network system. Users share network resources such as files and printers with other users. Interaction with servers is transparent to the user.
Your router supports the AppleTalk network protocol (both extended and nonextended) over FDDI, Ethernet, Token Ring, synchronous serial, and X.25 interfaces. For detailed information on AppleTalk, refer to the Router Products Configuration Guide.
Default: No
Action: If you plan to configure AppleTalk, circle Yes. If not, circle No.
If you plan to configure AppleTalk on your router, you must also decide whether to have multizone networks.
The Apollo Domain (Apollo) routing protocol is the native-mode networking protocol for Apollo workstations. This protocol enables an Apollo host to have interfaces on more than one physical network. Each physical network is identified by a unique 32-bit address in hexadecimal format. The address consists of a network number followed by a host number.
Your router supports packet forwarding and routing for Apollo on Ethernet, FDDI, and serial interfaces using HDLC and X.25 encapsulation. Direct attachment to the 12-Mbps Domain Token Ring is not supported.
Default: No
Action: If you plan to configure Apollo, circle Yes. If not, circle No.
If you plan to configure Apollo on your router, you must also determine the Apollo routing number.
The software on your router supports packet forwarding and routing for the Connectionless Network Services (CLNS) protocol, an International Organization for Standardization (ISO) implementation. CLNS provides the basis for DECnet Phase V.
To understand CLNS routing, you need to be familiar with the hierarchical concepts of domain and area. At the top of the hierarchy is a set of routing domains. The domain address uniquely identifies the routing domain. Within each routing domain are one or more areas. The area address uniquely identifies the area. For detailed information about how your router implements CLNS, refer to the Router Products Configuration Guide.
Default: No
Action: If you plan to configure CLNS, circle Yes. If not, circle No.
If you plan to configure CLNS on your system, you can provide router tag, domain, area, and station ID information, or you can use default values.
The Banyan Systems Virtual Integrated Network Service (VINES) protocol is designed for PC networks. Your router supports the VINES network protocol over all media types. For detailed information about how your router implements VINES, refer to the Router Products Configuration Guide.
Default: No
Action: If you plan to configure VINES, circle Yes. If not, circle No.
You can configure transparent bridging only if the subset image you ordered includes bridging. You can verify that your subset image has bridging capability by looking at the installed hardware banner that appears at first-time startup.
You configure bridging, like routing, for the system as a whole. That is, if you bridge a protocol, you must bridge it on all interfaces. For example, you cannot bridge XNS on one interface and route it on another. If you bridge XNS, you must bridge it on all interfaces. However, on the same system, you can bridge some protocols (on all interfaces) and route other protocols (on all interfaces). For example, you can bridge XNS, Vines, and AppleTalk on all interfaces, and route IP, IPX, and DECnet on all interfaces.
For more information about bridging, see the Router Products Configuration Guide. For more information about bridging commands, see the Router Products Command Reference publication.
Default: No
Action: If you plan to configure transparent bridging using, circle Yes. If not, circle No.
The local area transport (LAT) protocol from Digital Equipment Corporation (Digital) is the protocol used most often to connect to Digital hosts. LAT is a Digital-proprietary protocol. Cisco uses LAT technology licensed from Digital.
With the LAT protocol, you can establish a connection to a host, then pass your keystrokes to the host. A user can establish a LAT connection through a router running protocol translation to a Digital host, simply by entering the host name.
LAT cannot be routed because Digital's LAT protocol includes its own transport protocol (Layer 4 of the OSI reference model), which runs directly over Ethernet (Layer 2 of the OSI reference model) rather than over a standard routing layer. LAT must be bridged to pass between different network segments. The router provides the option of transporting LAT in protocol translation mode. A router with the protocol translation option can translate LAT to Telnet or X.25 for transmission over a WAN, which can be translated back to LAT on the other end of the connection.
You can configure this WAN-to-LAT translation to be transparent to the user. This configuration also avoids LAT time-out problems, which are common in WAN-bridged LAT. For more information about how your router implements LAT, refer to the Protocol Translation Configuration Guide and Command Reference publication.
Default: No
Action: If you plan to use LAT on this system, write Yes on the worksheet. If not, write No.
Currently, the Cisco 2500, Cisco 3000, and Cisco 4000 series support the Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI). An ISDN BRI connection consists of two B-channels that are each treated as a single serial line. You can use the B-channels with High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) encapsulation. Although each channel is treated as a separate line, you cannot configure the channels separately. A single switch type must be configured for the router as a whole.
The possible switch types are as follows:
Default: None
Action: On the worksheet, write the value associated with the switch type you plan to configure. The valid values appear in parentheses in the list above.
The Interface Configuration Worksheet lists two levels of information:
The setup command facility does not request system hardware information, but it is useful to write the information on your worksheet to complete your records. The setup facility does request interface parameters at first-time startup. The interface parameters depend on the decisions you make about the global parameters. For example, if you have not configured a protocol at the global level, you do not need to configure it at the interface level.
Figure 2-2 shows a sample Interface Configuration Worksheet. The "Blank Worksheets" appendix contains a blank worksheet for your convenience. Record information about your interfaces on the blank worksheets as you proceed through the following descriptions.
The values for the following system hardware information should be the same as those you indicated on the Global Configuration Worksheet:
Refer to the "Determining System Hardware Information" section and the "Determining Global Parameters" section earlier in this chapter for information about these values.
This section contains information about the interface parameters that you can configure through the setup command facility. Use this information to complete the Interface Configuration Worksheet.
In the following descriptions of the parameters that you determine, a Default: label marks the factory default and an Action: label marks your task for each parameter.
The setup command facility automatically presents each installed interface for you to configure. The facility presents the interfaces in the same order in which they are installed in the chassis. For example, if you have two Token Ring interfaces, you are prompted to configure interface TokenRing0 and then to configure TokenRing1.
The number of interfaces determines the number of columns in which you need to provide information. If you have more than four interfaces, you will need more than one worksheet.
Default: The default is the order in which the interfaces are installed in the chassis.
Action: Write each interface name across the top of the worksheet in the row labeled "Interface Name."
You can decide whether you want to configure an installed interface at first-time startup. The system shuts down the interfaces that you indicate you will not configure.
Default: No
Action: If you plan to configure a particular interface at first-time startup, write Yes in the column for that interface. If not, write No.
If you have a Token Ring board installed, select a speed for your network. You can enter 4 to set the Token Ring speed to 4 Mbps, or 16 to set the Token Ring speed to 16 Mbps. Once you set this value, the setup command facility does not ask you for it again.
 | Caution If you select the wrong speed, the ring will be brought down. |
Default: 16
Action: Write the correct Token Ring speed for your network on the worksheet.
Determine whether to use IP routing for a particular interface.
Default: No
Action: If you plan to use IP routing for an interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
If you plan to use IP routing on an interface, provide the IP address and subnet mask bits for that interface. Indicate values on the worksheet as follows:
| First Class | First Byte | Network Bits | Host Bits | |
|---|---|---|---|---|
| Max Subnet Bits | Min Address Bits | |||
A | 1-126 | 8 | 22 | 2 |
B | 128-191 | 16 | 14 | 2 |
C | 192-223 | 24 | 6 | 2 |
Determine whether to use DECnet Phase IV addressing on a particular interface.
Default: No
Action: If you plan to use DECnet Phase IV addressing for the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
If you will be using DECnet Phase IV addressing on an interface, you must also provide the route cost for that interface. Indicate a value on the worksheet as follows:
Determine whether to use IPX on a particular interface.
Default: No
Action: If you plan to use IPX on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
If you will be using IPX on an interface, you must also provide the network number for that interface as follows:
Determine whether to use XNS on a particular interface.
Default: No
Action: If you plan to use XNS on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
If you plan to use XNS on an interface, you must also provide the network number for that interface. Indicate the information on the worksheet as follows:
Determine whether to use AppleTalk on a particular interface.
Default: No
Action: If you plan to use AppleTalk on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
Remember, during configuration of the global parameters, you specified whether you wanted to configure multizone networks. Your answer applies to every interface you configure.
If you plan to use AppleTalk on an interface, you must also provide the other information for that interface as follows.
Determine whether to use Apollo Domain (Apollo) addressing on a particular interface.
Default: No
Action: If you plan to use Apollo addressing on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
If you plan to use Apollo on an interface, you must also provide the network number for that interface as follows:
Determine whether to use CLNS on a particular interface.
Default: No
Action: If you plan to use CLNS on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
Determine whether to use Banyan VINES on a particular interface.
Default: No
Action: If you plan to use VINES on the interface, write Yes on the worksheet. If no, write No. Repeat this for each installed interface you plan to configure.
Determine whether to use transparent bridging on a particular interface. (Remember that you cannot use the setup command facility to configure source-route bridging. To configure source-route bridging, you must use the command interpreter. Refer to the Router Products Configuration Guide for information on configuring source-route bridging.)
Default: No
Action: If you plan to use transparent bridging on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
The local area transport (LAT) protocol from Digital Equipment Corporation (Digital) is the protocol used most often to connect to Digital hosts. LAT is a Digital-proprietary protocol. Cisco uses LAT technology licensed from Digital.
With the LAT protocol, you can establish a connection to a host, then pass your keystrokes to the host. A user can establish a LAT connection through a router running protocol translation to a Digital host, simply by entering the host name.
Default: No
Action: If you plan to use LAT on the interface, write Yes on the worksheet. If not, write No. Repeat this for each installed interface you plan to configure.
After you complete the Interface Configuration Worksheet, go on to the "First-Time Startup" chapter.
