Zone IP servers to FC Storage via FCOE

We are planning to ISL a Nexus 5696 to MDS9710

With what I understand ISLing these switches would be similar to ISLing 2 fabric switches. however, if a server is connected to an 10g IP port how do we zone it?

how do we get the wwn number of the server?
Might be a basic question but I cant find anything on it.

Consider to study the Cisco Nexus 5600 Series NX-OS SAN Switching Configuration Guide first:…

The required steps will include:

  • First of all you need to decide if you would like connecting the Nexus switch using NPV or full fabric mode.
    Most deployments I have seen are using NPV mode.
  • I strongly recommend to deploy a port channel between the Nexus and the MDS switch.
  • You need to install and activate the feature FCoE.
  • To prevent data corruption due to cross-fabric talk, consider configuring unique FC-Maps.
    Default will be: 0e.fc.00- for example use 0e.fc.01 for fabric 1 and 0e.fc.02 for fabric 2.
  • Domain IDs needs to be static!!!

  • Now to verify the FCoE capability use the command “show fcoe”.
  • To see virtual FC interfaces, FCIDs and mac addresses use “show fcoe database“.
  • You need to create a FCoE VSAN and map it to your VLAN.
    Do not use the same VSAN ID for fabric A and fabric B!!!
  • The Ethernet interfaces - were the server CNAs are connected to - and virtual FC ports needs to be configured.
    A binding between this ETH interfaces and the vFCs to needs to be configured.
  • The vFC ports needs to be added to the VSAN.

Now you will be able to do the zoning.

Having Ethernet, the MAC address - not the IP - will be used to calculate the WWNs for the CNA ports...

I hope this will help to dive into your FCoE deployment?
