Nexus 5548UP - VFC error disabled

Go to solution

‎10-24-2013 02:01 AM

We are building a Datacenter with UCS 6248U FIs and Nexus 5548UP Switches.

The problem ist the FCoE configuration on the Nexus. After creating the vfC-Interface it is member of the default-vsan1. When we try to assign it to an other vsan (here vsan 100), it goes down with "error disabled".

We have only the Interface e1/7 in port-channel 60 bound to vfc60, vsan 100 associated to vlan 710

I hope anybody has an idea what's the problem.

Here is an extract of our configuration:

Hello Robert,

The port-channel status is SD and member link is still I state. Have you tried flapping the port-channel interfaces ?

Also, NPV feature is enabled on N5K and I don't see NPIV  enabled on it.

Are you planning to run N5K in NPV mode ? If yes, I need to verify if FI can be connected to FC switch operating in NPV mode.

I guess FI is in FC End host mode ( NPV ) and it needs to be connected to FC switch with NPIV feature.

Hello Robert,

What is the UCSM and N5K version ?

From N5K

show feature | grep -i enabled

show fcoe

From UCS FI

connect nxos

show port-channel summary

--- same set of commands as you shared from N5K

Hello Padma,

N5K-Version is version 5.1(3)N2(1)

UCS-Manager is 2.1(2a)

We've configured the UCS with UCSM but the result looks similar to the N5K: 



N5K:

Hello Padma,

this was the solution. After enabling npiv the vfc  shows "NPV upstream port not available". After disabling npv everthing  is fine. I confused npv and npiv.

Thank you for your help

Robert
