Poor failover performance of WS-SVC-ASA-SM1 in WS6506-E

Hello, I am trying to deploy an active/active multi-context solution using the hardware noted above.

I believe I have done all required to get this working however I am still seeing fail over times of

around 50 seconds.

The ASAs blades and the supervisors have identical images:-

Cisco Adaptive Security Appliance Software Version 9.1(2) <context>
Device Manager Version 6.5(1)
Compiled on Thu 09-May-13 16:20 PDT by builders
Hendon up 17 days 21 hours
failover cluster up 26 days 21 hours
Hardware:   WS-SVC-ASA-SM1

Cisco IOS Software, s72033_rp Software (s72033_rp-ADVIPSERVICESK9-M), Version 15.1(2)SY4a, RELEASE SOFTWARE (fc1)

I have this config on both the 6506 supers:-

firewall autostate
firewall multiple-vlan-interfaces
firewall module 6 vlan-group 56
firewall vlan-group 56  12,41-44,51-54,56-60,68,69,72,73,76,77,88,97-99,199,858,860,2009,2012,2041
firewall vlan-group 56  2051,2053,2054,2057,2060,2076,2077,2088,2098,2099,2142,2152,2156,2158,2159
firewall vlan-group 56  2188,2197,2199

I can paste in further content on request. Any help would be much appreciated.

Many thanks
Cisco

First thing that I think of when I hear about forwarding delay about 50 second is: Are you using STP in your network? That sounds like forwarding delay caused by STP convergence.

Thanks for your quick response Predrag. Yes we are using spanning tree. I have a 4500
used for connecting 'users' to vlan 2060 and that 4500 has two links, one to each of the 6506 switches on vlan 2060.

Having said that now it is of course the 4500 that is taking the time to fail over..but i can't turn if off due the loop....thinking we should enable rapid spanning tree....will give that a go and let you know. Thanks

Thanks again

Hello Predrag, I enabled rpst and 'failover autostate' and all is much quicker now, thanks for that.

Would you advise disabling spanning tree altogether on the access switches and leave it running on  the two 6506s which contain the ASA SMs ?

Thanks
