CSM fault tolerance takeover time

Hi,

I am currently testing the fault tolerance feature on the CSM. During the testing I discovered that the takeover from active to standby is immediate when you reboot the active CSM. However when the active CSM comes back online it does not take over immediately. What I am seeing is that it takes between 3-4 minutes before the active module does a preempt.

Is there a hidden timer similar to preempt delay in HSRP at work here and is it possible to tweak it somehow?

Many thanks,

Murtaza

Re: CSM fault tolerance takeover time

there is no hidden parameteres.

The delay is to make sure the flows can be copied from active to standby before it takes over.

Gilles.
