I have configured FWSM as inter chassis Active Active failover.
The failover works just fine only for 10 mins before both context on both units shows active and peer context as failed.
I am not sure what the issue is. The failover and Stateful Vlan are trunked on L2 etherchannel (20 Gig links). I do not see any packet drops on etherchannel physical links, however do see a lot of packet drops on Failover and Stateful VLAN only on FWSM module second 6509 switch.
Any thoughts will be helpful.
