Description: * | Symptom: - N56k sends a name server PLOGI_ACC using vsan global FCF mac instead of interface MAC. ethanalyzer can be used to capture the mac address used. - host's affected will not have access to their storage. - host's affected will not have fcns "fc4-types", "symbolic-port-name" and "symbolic-node-name" registered with the name server.

Conditions: all of the following must apply for the issue to be a hit on this bug.
- Nexus 5600 or 6000 only "N55k is not affected". - software code 7.x. - vfc's are configured to using "bind mac-address":
interface vfc301 bind mac-address 0019.993E.D302 switchport trunk allowed vsan 10 switchport description FCoE-to-Blade no shutdown
Workaround: configure the following:
- remove the vfc interfaces with bind mac-address. - use one vfc interface that is bind to the physical interface. - enable NPIV on the switch.
feature npiv interface vfc 1 bind interface port-channel 1 switchport trunk allowed vsan 10 switchport description FCoE-to-Blade no shutdown
with this setup, instead of using multiple vfc interfaces each one that is bound to a MAC. we will use on interface, and all the host's will login through that one vfc which is allowed through NPIV.
