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.

[hailin huang]

yes,i swap .The sfp is glc-t 1G.

but i do not konw type is 10G

type:10 gbase lr

model:glc-t

vendor;cisco

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.

[hailin huang]

thank you .the problem is ok

The agent of the module is a problem.
