[c-nsp] FWSM failover time

Hi all, sorry for my eng ;)



Ok, here is  my story about 2 catalyst 6500 boxes, with installed fws
blades. Between fws are configured as transparent with A/A failover. Nodes
are connected with 2x10Tg EC.

When one of boxes filed, initial failover begins, but the time between first
node stops forwarding and the second node begins forwarding is too big,
about ~7 sec.

Any suggestions to how decrease failover time?



*First box failover config:*

*msk-dc-fwm-c2-1/9#    sh run failover *

failover

failover lan unit primary

failover preempt 1

failover lan interface failover-lan Vlan104

failover polltime unit msec 500 holdtime 3

failover link failover-state Vlan105

failover interface ip failover-lan 192.168.255.253 255.255.255.252 standby
192.168.255.254

failover interface ip failover-state 192.168.255.249 255.255.255.252 standby
192.168.255.250
