L2 connectivity issue

Hello All,

On checking, the ISE device is not reachable. 

From the switch end logs, it's showing connected but not reachable via ping. 

Always did shut/unshut to bring up the ISE device. The switch end logs look wired.

What is the meaning of "operational Transmit Flow Control state changed to off"

Try hardcoded speed and duplex in SW port

Can you post the configuration applied on the eth 1/38

based on the information of interface it is nexus switch - can you post show nexus version it is ?

check the cables and replace the SFP and test it.

Other suggestion remove the SFP default  the interface and change the speed 1000  and apply relevant config  and inset the SFP, connect ISE and monitor, (check STP config too)

no negotiate auto
speed 10000
duplex full

Also post below output you have still the same issue :

show platform software ethpc event-history interface
