Hi,

I'd recommend seeing if the reseller you bought the glc-t's from can exchange them.  There appears to be problems with those sfps.

Hi,

On the fabric interconnect if you connect nxos and issue a "show int eth 1/7" and a "show int eth 1/7 transceiver details", what does it show?

Hi,

Are you able to swap out the glc-t sfp with another one and see if that works?  The sfp above appears to think its  both a glct and 10gbase-lr sfp.
