Solved: CSS 11506 redundancy

jcarvalh · ‎02-27-2008

Hello.

I have one CSS with two SCM modules (I have no more modules on the CSS).

I configured it in one-armed mode and now I need to configure redundancy between both SCM.

At this moment I have one active and the other is passive and if I take one SCM down the other takes place.

However if I unpluged the cable for the giga port in the active the passive does not became active. Is it possible to configure both SCM with a more sofisticated redundancy method?

In documentation I couldn't find any help.

Best regards,

Joao

Hi Joao,

Unfortunately, the SCM's in the CSS are redundant only from a hardware perspective. They cannot be configured to take over from a "software" perspective when an interface goes down.

I guess one potential thing to do would be to have a customer script with a keepalive to test ip connectivity and when/if that keepalive in software fails, have the script run the commands to take the SCM down.

Regards

Pete..
