To check the SSB mastership from the LEDs, look on the faceplate at the front of the

"Check the Redundant SSB LEDs" on page

The SSB has two groups of LEDs: online/offline LEDs and status LEDs. The online/offline

LEDs indicate whether the SSB is online or offline. The status LEDs indicate what type

of task the SSB is performing.

The command output displays the alarm date, time, severity level, and description. An

SSB failure or removal generates an

100-Mbps Fast Ethernet link between the SSB and the Routing Engine. This link transfers

routing table data from the Routing Engine to the forwarding table in the Internet

Processor ASIC. The link also transfers, from the SSB to the Routing Engine, routing

link-state updates and other packets destined for the router that have been received

through the router interfaces.

To determine the details of the SSB error messages in the system log file.

Periodically check the system log messages on the management console for messages

sent by the SSB. During normal operation, the SSB notifies the Routing Engine of any

errors it detects.

To display the SSB error messages in the system log file, use the following CLI command:
