NEXUS 7000 xcvrInval

Hi,

I have some Nexus 7000 with FET-10G with xcvrInval status

Eth7/33          N5k-S1-3T-1/3   xcvrInval trunk     auto    auto    Fabric Exte

and some other FET-10G with notconn status

Eth7/8           FEX-101         notconnec 1         auto    auto    Fabric Exte

If I inter exchange the position of both FET-10G the status port doesn´t change

FET-10G from 7/8 to 7/33

FET-10G from 7/33 to 7/8

7/33 holds xcvrInval status

7/8 holds notconnec status

I have reconfigured from default interface with same results

Next you´ll find the same serial number in deferent port, the diference is the current

when is xcvrInva or when is notconnec

What can I do to get FET10G in e7/33 validated?

Hi Erick,

Are you using the FET-10G to connect to a fabric extender? These optics are only usable between a N7K/N5K and the fabric extender. If you have configured "switchport mode fex-fabric" and still receiving the "Transceiver validation failed" error messages this could be a sign of something else possibly hardware related. If you are trying to use the interface for something other than connecting a FEX to the Nexus then that won't work.

Hi Ans,

You are rigth, I have defaulted againt the port, now configured with switchport mode FEX, and now the FET-10G is validated
