Maintaining the M120 Host Subsystem
Purpose
For optimum router performance, verify the condition of the host subsystem. The host
subsystem comprises a Routing Engine installed directly into a CB.
Action
On a regular basis:
•
Check the LEDs on the craft interface to view information about the status of the
Routing Engines. For more information about the LEDs and the display, see
Interface Description” on page 11
.
•
Check the LEDs on the CB faceplate to see information about them.
•
Check the LEDs on the Routing Engine faceplate to see information about them.
•
To check the status of the Routing Engines, issue the
show chassis routing-engine
command. The output is similar to the following:
