Using a GLC-T with a Nexus 3548

[Andrew Cormier]

Hi,

I am sorry I didnt get the exact message but I am hoping someone can help.

We have two nexus 3548s we are deploying and have 4 GLC-T  SFPs

I plugged them in to ports Eth1/1 and Eth1/2 on both switches.

When the links didnt come up I did a sho int status and I dont remember exactly what it said but it was something like

sfpUnsupported or sfpInvalid or sfpUnknow. I dont remember the exact term.

Any thoughts?

I thought I would see the errors in the logs but alas.. no.

Hi,

Looking at this link:-

The GLC-T is supported on your 3548 - Are your GLC-T genuine cisco parts

They are supposed to be genuine cisco parts.

Bought from a certified cisco reseller.. they are labled cisco parts

PN 30.-1410-03

each has a unique SN and QR code

FIXED! Sho int statu was saying sfpInvali

When I changed the port speed to 1000 it connected properly. Good to know lol :)

Hi,

As Alex also noted, you usally get that message when you purchase the optics from a none Cisco certified parter/reseler or from Cisco directly.  It also may help if you set the speed under these interfaces.

Hello,

Configure the interface speed to 1000 on Eth1/1 and Eth1/2 and it should resolve the issue.
