Chapter 4. Using OPCON

This chapter describes the OPCON interface con®guration and operational commands. It includes the following sections:

v ªAccessing the OPCON Processº v ªOPCON Commandsº

Accessing the OPCON Process

When the router starts for the ®rst time, a boot message appears on the console.

Then the OPCON prompt (*) appears on the console, indicating that the OPCON

process is active and ready to accept commands.

The OPCON process allows you to con®gure, change, and monitor all of the

router's operating parameters. While in the OPCON process, the router is

forwarding data traffic. When the router is booted and enters OPCON, a copyright

logo and an asterisk (*) prompt appears on the locally attached console terminal.

This is the OPCON (OPerator's CONsole) prompt, the main user interface that

allows access to second-level processes.

Some changes to the router's operating parameters made while in OPCON take

effect immediately without requiring reinitializing of the router. If the changes do not

take effect, use the restartcommand at the * prompt.

At the * prompt, an extensive set of commands enables you to check the status of

various internal software processes, monitor the performance of the router's

interfaces and packet forwarders, and con®gure various operational parameters.

OPCON Commands

This section describes the OPCON commands. Each command includes a description, syntax requirements, and an example. The OPCON commands are summarized in Table 3. To use them, access the OPCON process and enter the appropriate command at the OPCON prompt (*).
