FWSM module multicast traffic problem

Hi,

We have a failover pair of FWSM blades running the latest software version - 3.1(3). One of the key reasons for upgrading to this version was the multicast support introduced in this release train.

Now, there's not a great deal to configure on the FWSM to enable multicast, and initally it worked as advertised with a multicast source located behind the firewall accessible on its group address without issue.

The traffic suddenly stopped working one day which we're working to try and resolve, but the slight odd thing was the appearance of a non-existant interface in the Outgoing interface list e.g:

Outgoing interface list:

Tunnel0, Forward, 00:11:13/never

There is no Tunnel0 on the FWSM - can anyone please explain this?

Thanks
