FWSM Primary delay returning to active

Hi,

We have several FWSM in 2 6500 chassis and a few days ago the primary FWSM rebooted itself for unknown reasons and the secondary FWSM took over as planned.

But the primary FWSM has, after several days, switched back over to active automatically.

Question is, does anyone know why there would be such a long delay for the primary to request active mode?

Re: FWSM Primary delay returning to active

There is no preemption support in Cisco FWSM (Or ASA/PIX for that matter) in Active/Passive mode. The primary most probably took over because something won't down on the 'Secondary (Active)' unit e.g. a monitored interface, triggering the failover. Check the output of the 'show failover history' command to see what exactly caused the failover.

In multiple context mode (Active/Active) you can configure pre-emption on a per context basis.

Please rate if helpful.

Re: FWSM Primary delay returning to active

Hi,

Thanks for your reply. This is the log output when the primary decided to take over as active:-

May 27 14:22:41 10.10.0.18 %FWSM-1-104002: (Secondary) Switching to STNDBY - Other unit want me Standby

May 27 14:22:41 10.10.0.18 %FWSM-1-104001: (Primary) Switching to ACTIVE - Set by the CI config cmd

Here is the failover history from the standby unit. It did not reboot like the primary did a few days ago.

Re: FWSM Primary delay returning to active

It seems the last failover was caused by someone issuing the 'failover active' command on the standby unit, or the 'no failover active' on the primary one, was that done by you?
