FWSM Failover times

[jbigrow]

Hi Folks

I have 2 6509's with fwsm in them. They are xconfigured in active standby failover.... default values

the 6500's are OSPF routers also. Everything is redundant HSRP, FWSM etc.

when we reboot one of the 6500's it takes approximately 45 seconds for the standby FWSM to become active.

Is this normal? can the time be shortened?

any comments appreciated.

Hi,

The initial 15 seconds detection time can be reduced to 3 seconds, by tuning failover polltime and holdtime to the following:

"failover polltime unit 1 holdtime 3"

Also keep in mind after  switchover new active will establish nbr relation with nbr router. At any point of time standby does  not participate in OSPF process.  so in short new active have to  re-establish adjacencies.

Hope that helps.

Thanks,

Varun

I have to ask does the default settings account for the 45 sec + failover time?
