FCoE Nexus 5000


I have a Nexus 5000 conected with a UCS C-200 with qlogic CNA in FCoE. The ethernet traffic is ok, but FC dont work fine, i thinks that i have configured all ok, by the show int vfc show the trunk vsan in initializating mode and i dont find what is the problem

My configuration

vlan 701
  fcoe vsan 1
  name FCoE-Vsan1

interface vfc1
  bind interface Ethernet1/9
  switchport description Conexion FC con UCS1
  no shutdown

interface Ethernet1/9
  description Conexion FCoE con UCS1
  switchport mode trunk
  spanning-tree port type edge trunk

I need configure anything in UCS?.



Under your ethernet 1/9 try adding:

switchport trunk allowed vlan 1, 701

Assuming vlan 1 as your native default vlan and 701 is FCoE vlan, this should bring up vlan 701 to your CNA.

What model CNA are you using and what type of cable are you using?


The CNA is a Qlogic in a UCS with a SFP-10Gb-SR transceiver in UCS and Nex-5000.


So the CNA is QLE814x model and not a QLE815x? 

Qlogic QLE 8152-CNA 2port 10Gb SFP+ Copper

Okay..its not the issue I have seen before where someone was using TwinAx with a QLE8142.  Those only support fiber.


I have a SFP 10Gb-SR wit multimode fibre in both sides.
