Sup720 Redundancy

mmelbourne · ‎01-16-2005

I have two Sup720 modules installed in a 6509 chassis and config sync appears to be working; I get positive syslog messages stating that the configuration has been sync'd with the standby Supervisor and a forced manual failover suggests it is working as expected.

However, is there a way to connect to the 'standby' supervisor engine to check the status of its configurations? Previously, with CatOS, it was possible to "session" to module 15 or 16 and then check the configuration (even though all interfaces would be down and configuration mode inaccessible). I've tried the session command, but this doesn't work and is for use when connecting to other Cat6k modules (e.g. IDS etc).

If you are running 12.2(18)SXD releases, you can do a remote login module command. In my lab I have active Sup in slot 5 and standby in slot 6 and running 12.2(18)SXD2
