I'd like to understand where the IP control & forwarding planes resides within the Cisco MDS 9000 Family 14/2-port Multiprotocol Services Module. Due to the low number of GE interfaces per card and for resilience, if FC to IP conversion takes place on one card but the egress GE is unavailable - can the architecture tolerate IP switching to another card and GE port in the same chassis and if so can an IP Routing protocol be used between MDS9506's to determine that as the best contingent path ?
There are various approaches that will achieve the resilience you need when a single IPS gigabit Ethernet port goes down.
With Virtual Router Redundancy Protocol (VRRP) running on the IPS blade you will experience iSCSI session drop or FCIP link flap when the backup interface takes over the VRRP ip address.
With Ethernet portchannel you will see no disruption, but the two ports need to be same odd/even pair on same module, eg gig1/1 and 1/2.
Another common approach for FCIP is to create multiple FCIP links/tunnels using different IPS ports and if any one port fails FCIP traffic will not be interrupted. Multiple FCIP links can be bundled into a portchannel.

Is it supported or NOT supported? It's a frequently asked question.
Before APIC, release 2.3(1f), transit routing was not supported within a
