Question or Symptom

When upgrading the CBOS on Cisco routers, one might find that they can't access RMON through normal means (hitting <CTRL>-C when the Alarm light lights).

Resolution

To go into RMON when this occurs, boot the router normally, and go into ENABLE mode, and type the following:

 debug monitor on <ENTER>
   
 reboot <ENTER>
 

At the "Hello!" prompt, hit <ENTER> twice to put the router into RMON mode. The CBOS may now be upgraded using the normal procedure. It will be necessary to maunally exit the RMON mode, using the key sequence:

 => m0 <ENTER>
 => rb <ENTER>
 

After the CBOS upgrade and reboot, RMON should be accessible through the normal means.
