Router Conﬁguration Functions

The Conﬁguration Manager provides remote router conﬁguration functions. Speciﬁcally, it lets you

• Add network interfaces to the router based on defaults.

• Customize network interfaces for your network environment.

• Specify the router’s hardware conﬁguration.

• Conﬁgure the router’s connection to the Technician Interface.

• Specify administrative information about the router.

Adding Network Interfaces

The Conﬁguration Manager simpliﬁes router conﬁguration by providing default values for most of the parameters required to conﬁgure an interface. Chapter 2 describes how to add network interfaces.

1-1

Configuring Routers

Customizing Network Interfaces

After you add an interface to a router, you can use the Conﬁguration Manager to customize it. The Conﬁguration Manager provides management access to all parameters associated with an interface. These parameters consist of the physicallayer (line) parameters, datalink-layer (circuit) parameters, and network-layer (bridging/routing) parameters. You can perform the following functions:

• Edit the line parameters associated with the interface.

Services

• Delete and rename circuits, as well as move a circuit to another interface. Chapter 4 describes how to perform these tasks.

• Add protocols to and delete them from the circuit associated with the interface. Chapter 4 describes how to perform these tasks.

• Edit bridging and routing protocol parameters. You can access these parameters on a system-wide or interface-speciﬁc basis.

Refer to the appropriate protocol-speciﬁc guide for instructions on editing bridging and routing protocol parameters.

• Add multiple Internet Protocol (IP) addresses to a single circuit that supports IP. Chapter 4 describes how to do this.

describes how to edit line parameters.

Specifying Router Hardware Conﬁguration

In dynamic and remote modes, the Conﬁguration Manager does not require you to specify router hardware. In local mode, however, the Conﬁguration Manager requires you to specify the hardware conﬁguration whenever you create a new conﬁguration ﬁle.

See “Starting a Conﬁguration in Local Mode” later in this chapter for information on how to specify router hardware.

Conﬁguring Line

Conﬁguring the Router Connection to the Technician Interface

The router’s console port connects the router to the Technician Interface. Site Manager provides default settings for the console conﬁguration; howe ver, you can use the Conﬁguration Manager to access and reconﬁgure all console parameters.

Chapter 5 describes how to conﬁgure the router’s connection to the Technician Interface.

1-2

Specifying Administrative Information

You can use the Conﬁguration Manager to specify a system name, a system contact, and a system location for the router. This information appears in the main Site Manager window (Figure 1-1), which appears at Site Manager start-up.

Chapter 6 describes how to specify administrative information.

Using the Configuration Manager

Figure 1-1. Bay Networks Site Manager Window

1-3

Configuring Routers

Operating Modes

You can perform all conﬁguration functions in one of three modes:

• Local

• Remote

• Dynamic

For each function you can perform, the Conﬁguration Manager displays the same windows in the same sequence regardless of the operating mode. For e xample, the Conﬁguration Manager displays the same sequence of windows when you conﬁgure the Bridge global parameters in local mode as it displays when you conﬁgure them in dynamic mode.

The Conﬁguration Mode ﬁeld in the upper-left corner of each window identiﬁes the Conﬁguration Manager’s current operating mode. For example, Figure 1-2 shows the Edit Bridge Global Parameters window when the Conﬁguration Manager is running in local mode.

1-4

Figure 1-2. Edit Bridge Global Parameters Window in Local Mode

The following sections describe each operating mode.

Local Mode

Using the Configuration Manager

Use local mode to create or edit a conﬁguration ﬁle locally on the Site Manager workstation for later implementation on the router. Unlike remote and dynamic modes, local mode does not access a router or automatically display the router’s hardware conﬁguration. You enter the router’s hardware conﬁguration when you create a new conﬁguration ﬁle or edit a ﬁle with hardware changes.

To conﬁgure a router in local mode, you must

• Open a conﬁguration ﬁle. You can create a new conﬁguration ﬁle or open an existing one.

• Specify the router’s hardware conﬁguration.

• Use the Conﬁguration Manager to perform all desired router conﬁguration functions (adding and conﬁguring interfaces, and so forth) as described in subsequent chapters.

• Save the conﬁguration ﬁle to the Site Manager workstation. See Chapter 3 for more information.

• Implement the changes. To implement your conﬁguration, you must — Use the Router Files Manager to select TFTP to transfer the conﬁguration

ﬁle to the router. — Use Site Manager to reboot the router with the conﬁguration ﬁle. Chapter 3 describes how to implement the conﬁguration changes.

See “Starting a Conﬁguration in Local Mode” later in this chapter for information on how to begin conﬁguring the router in local mode.

1-5

Configuring Routers

Remote Mode

Use remote mode if you can access the router over the network, but want to implement the conﬁguration at a later date.

To conﬁgure a router in remote mode, you must

• Conﬁgure the router connection options that identify the router you want to

• Use the Conﬁguration Manager to perform all desired router conﬁguration

• Save the conﬁguration ﬁle to the Site Manager workstation. When you save an

conﬁgure and that provide Site Manager with an SNMP community that has read/write access to the router.

After you specify the router connection options and select the remote operating mode, the Conﬁguration Manager uses SNMP GETs to retrieve and display the router’s hardware conﬁguration in the Conﬁguration Manager window. Optionally, if you specify a conﬁguration ﬁle stored in the router’s ﬁle system, the Conﬁguration Manager uses TFTP to automatically retrieve that ﬁle for local editing.

• Implement the changes. To implement your conﬁguration, you must use Site Manager to reboot the router with the conﬁguration ﬁle. See Chapter 3 for more information.

See the section “Starting a Conﬁguration in Remote Mode” later in this chapter for information on how to begin conﬁguring the router in remote mode.

Dynamic Mode

You use dynamic mode if you can access the router over the network and want to conﬁgure the system in real time.

To run the Conﬁguration Manager in dynamic mode, you must

• Conﬁgure SNMP options that identify the router you want to conﬁgure and

• Use the Conﬁguration Manager to perform all desired router conﬁguration

• Save the conﬁguration ﬁle to the router’s ﬁle system if you want to maintain a

record of the changes you made. Refer to Chapter 3.

You should not use dynamic mode to create an entirely new router

Also, conﬁguring a router in dynamic mode can interrupt service, depending on the attributes you modify. Be careful when modifying the global attributes of protocols. For example, changing the size of the bridge forwarding table will ﬂush and recreate the table, which can brieﬂy affect performance.

The way that you proceed depends on whether you open an existing or new conﬁguration ﬁle, as described in the following sections.

Opening an Existing Conﬁguration File

To open an existing ﬁle, select it and click on Open File. You can specify the ﬁle you want to open in either of the following ways:

• Click on the Path List, Directories List, and File List. The Path List shows the path from the root directory to the current directory . Select from the Path List to move up a directory level. The Directories List shows the directories available from the current directory. Select from the Directories List to move down a directory level. The Files List shows ﬁles available from the current directory . Y our current selections appear in the Path, Directory, and File boxes at the top of the window.

• Click on the appropriate box (Path, Directory, or File) and type a path, directory, or ﬁle.

Once you select a ﬁle and click on Open File, the Conﬁguration Manager window displays a logical image of the rear panel associated with the router you selected. (Figure 1-5 shows the Conﬁguration Manager window as it appears if you have not already speciﬁed the router hardware.) At this point, you should specify the router’s hardware conﬁguration if you haven’t already done so. Proceed to the section “Specifying Router Hardware.”

Using the Configuration Manager

Opening a New Conﬁguration File

To open a new ﬁle, enter the name in the File box and click on Open File. Another way to create a ﬁle is to enter its name in the Path box at the top of the

window and press Enter. To specify a new directory, enter its name in the Path or Directory box and press Enter.

You must have write-access privileges to the directory where you want to create a conﬁguration ﬁle.

Using the Configuration Manager

You must now specify the router’s hardware conﬁguration.

Specifying Router Hardware

You specify the router hardware in local mode only. You can add hardware to empty slots and change the hardware in occupied slots. The procedure for both is the same.

Note:

When you change hardware in a slot containing conﬁgured cir cuits, the

Conﬁguration Manager automatically deletes the circuits.
