Actve/Actve FWSM shared interface can't join f/o group

[khary]

I have 2 6500/FWSM in multiple mode with 3 security context. I am sharing VLAN 800 as the outside of all 3 context.

Context 1 and 2 are in failover group 1. However, I am not able to add the 3rd context to failover group 2. I received the following error:

ERROR: Cannot set failover group due to a conflict with a shared interface in another failover group.

Is shared interfaces a capability of the FWSM ver 3.1(4)?

Each security context will need there own outside interface. Having 3 contexts; is equivalent to separating the FWSM into 3 devices.

There is another string that is similar to what you need.

Please read the cascading context string on this forum
