For optimum router performance, verify the condition of the SIBs.
On a regular basis:
Observe the status of the SIBs by checking the LEDs on the SIB faceplate. For more
information on the SIB LEDs, see "M320 Craft Interface SIB LEDs" on page 31.
To check the status of the SIBs using the CLI, issue the
command. The output is similar to the following:
