linux server connection failure

[hkmin]

I have connected a Linux server by teaming on the Catalyst 9407. If the server down the active port, it will fail over normally, but if it's returned, the mac will come up from both interfaces connected to the 9407. Does anyone know what the problem is in this situation?

Can you post both the side configurations? What Linux distribution are you using? I have used it with  Ubuntu and Cat 9K switches that work as expected.

It is set to access port on 9407#1,#2. Linux version is Rhel 9.4.

C9407#1,2 configuration is below

int gi1/0/5

 switchport mode access

 switchport access vlan 100

If you have that issue with the access port, suggest changing port-channel and testing it

Is this a Linux server issue or a switch issue?
