FCoE over VPC

[Dave Mumford]

Hi, I just need clarification as to whether FCoE over VPC is supported. 

The scenario we have will be Lenovo blade chassis with integrated switches, connecting northbound to Nexus 55192 switches. Previously I've setup similar networks using IBM blade chassis with Nexus 4001i switches using vpc northbound for ethernet traffic to the Nexus 5K and separate 2x10g portchannels northbound for FCoE traffic, therefore keeping the isolated SAN-A / SAN-B topology.

see below figure 9.

If we were to run the FCoE over the VPC we'd need to then run the SAN-A and SAN-B VLANs over the VPC peer link, in my mind this breaks the isolated SAN-A / SAN-B , is thsi correct ? is FCoE over VPC in this scenario supported ? Any help appreciatedDave.

Thanks,

Dave

Hi Dave

Please see 8.1 Cisco Nexus 6000 Series Access Layer Configuration with FEX and EvPC ff in

In end-to-end FCoE designs, SAN A and SAN B separation can be achieved physically or logically by separating the FCoE VLANs that are carried across the LAN.
