Hello Community,
I have encountered interface down when migrating c3750x-48 interface to Nexus 93108TC-EX.
The end host is a legacy network and it uses 100M interface.
Nexus 93108TC-EX has GLC-TE interface to accommodate migration coming from c3750x-48.
Below are the configuration, interface properties, and status:

TSHOOT:
Apply interface as spanning-tree port type edge but to no avail.
I tried to undo hardcode to use auto neg but still physically down.
93108TC-EX(config-if)# no speed 100
93108TC-EX(config-if)# no duplex full
93108TC-EX# sh int status
Eth1/1 XXXX notconnec 200 auto auto 10g
Is this something related to negotiation, duplex, speed still?
I just notice that the MDIX is off on nexus interface by default, I haven't tried to enable. Can this be solve?
Thanks,
