Nexus 56128P Fibre Channel Interface

[jguirlinger]

Hi everybody,

I'm installing a Nexus 56128P and I try to configure Fibre Channel native interface on GEM N56-M24UP2Q.

I have configured the ports to be fc interface

slot 2

port 1-24 type fc

Then i have reloaded the module, but no fc interface appeared (and no more ethernet interface 2/x).

I checked the license, i have the FC_FEATURES_PKG installed but "unused".

I guess i missed something, but can't figure out what.

Any idea ?

After the port type has been changed from Ethernet to FC, the FC port will not be enabled on the switch until FCOE feature is enabled:

N5K(config)#feature FCOE

C license checked out successfully

fc_plugin extracted successfully

FC plugin loaded successfully

FCoE manager enabled successfully

FC enabled on all modules successfully

Enabled FCoE QoS policies successfully

After that, we verify that the port type is changed successfully and the FC ports appear on the switch:

N5K# show interface brief

Thanks, that solved my problem !

But I don't understand why we need FCoE feature for pure FC interface, I don't need FCoE on my switch. it's at least not intuitive. What is the relationship between FC and FCoE feature ?

Hi Julien

I agree with you 100% ! and it's not well documented either.

Cheers

Hi gents,

I've followed this post. So do you know whether the Chassis Storage License N56128-128P-SSK9  is required in order to enable FC native on some of the ports in the fixed module? I understand the license is required for enabling FCoE ..  what about for FC native only?

Your assistance is much appreciated.
