High level, for now, i only see inconsistency on the config interface TenGigabitEthernet1/4/1 compare to others

disconnect the port and default the information and put the configuration from the work port and test it.

later day i will look deep and let you know if i see anything abnormal

can you also post-show module from cisco switch side.

Hello BB,

I have already tried that. I have change  interfaces on both side ( Switch and router). but that the same result.

2 suggestions :

1. Configure different port from different module and join to teh Port-channel by removing (not working one)

2. at maintenance window, shutdown Port-channel both end and check
