Chassis Monitoring and Troubleshooting

From the command-line interface (CLI), you can display information about the chassis components using the commands in the show chassis hierarchy. These commands get their information from the chassis software process, which runs when the router is up and running. If the SCB, SSB, SFM, or FEB is not running, no information about chassis components is available through the CLI.

Table 27 summarizes the CLI commands you can use to monitor the router chassis. In the table, the commands are grouped by functionality. In the remainder of this chapter, they are explained alphabetically.
