I'm configuring two FWSm within the same 6500 chassis. I trunked a VLAN to the two modules.
I created a SVI on the MSFC and created an interface on one of the two FWSM. Everything works fine I can ping MSFC from FWSM and FWSM from MSFC. On the other FWSM I did the same thing, trunked the VLAN, configure the vlan interface on the admin context and issued sh int vlan xx. the output shows a "IP address unassigned". I issued shut / no shut, removed the vlan from the FWSM reallocated it again etc.... It keeps on being marked as "IP address unassigned"
The two modules are configured for failover.
The module on which I can see the ip address is assigned is the primary module the one on which the IP address remain "marked" as unassigned is the standby one. However supsecting this could be somehow related to the failover I issued the no failover command on the standby module so the FWSM on which I can't ping the MSFC is now in the Failover OFF (pseudo failover) state.
I even tried with another vlan so that only the previously standby unit is configured with it and even if it is no longer shared accross the two FWSM it remains maked as "ip address unassigned".
I don't know what to do to get it up and running at this stage...
