Port already in a port-channel

[Rem Markov]

Hey everyone!

I have a N9K c9372PX with FEX N2K-C2232PP-10GE.

In Eth101/1/1 I have previously configured channel-group and access vlan.
When trying to default the interface I recieve:
ERROR: port already in a port-channel, no config allowed.

The only has one setting to it:

switchport access vlan 123

The main problem is that there is no Port-channel associated with this interface and the previous port-channel is deleted.
(Trying to recreate the PO didn't help)

I assume it a bug? Because all the workaround didn't help nor matched the case.

There is force mode in port channel in nexus 

This mode make all ports member use same config that port channel use.

You need to shut the port channel first then try defualt this port

There is no Port-Channel associated with the interface
And the one that was is non-existent now

Hello,

you might want to try a secure-erase for the FEX:

But I really don't want to factory reset the whole FEX. Just this one interface.

It was solved!

Finally It tried looking at port-channel summery, and I have seen a port-channel with the interface in it. even though he was never part of it.
After deleting the port-channel everything worked.
