Slot 1:
State:
The command output displays the number of times the mastership has changed, the
SSB slot number or and the current state of the SSB:
0 1,
command output displays the temperature of the air passing by the SSB, in degrees
Centigrade. It also displays the total percentage of CPU, interrupt, heap space, and buffer
space being used by the SSB processor, including the total DRAM available to the SSB
processor. The command output displays the time when the SSB started running and
how long it has been running.
To display the status for a particular SSB, use the following command:
user@host> show chassis ssb slot
To verify the status of the redundant SSB by checking the redundant SSB LEDs.
Periodically check the SSB LEDs to verify that the SSB is online or offline and the type
of task it is performing.
To check the SSB LEDs, look on the faceplate at the front of the router (see
on page 721).
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.
