Hi,
I followed Redhat teaming configuration guide [1] to configure NIC teaming, except LACP runner, others work as expected. Here is my config file (from example lacp_1.conf): { "device": "team0", "runner": { "name": "lacp", "active": true, "fast_rate": true, "tx_hash": ["eth", "ipv4", "ipv6"] }, "link_watch": {"name": "ethtool"}, "ports": {"eth0": {}, "eth1": {}} } I can create LACP team interface, "teamdctl team0 state" shows correctly, but after I perform: $ ip link set up dev team0
$ ip a shows NO-CARRIER and state is DOWN for team interface. dmesg shows both eth0 and eth1 link are ready, but team0 is not.
Also, I see messages saying, "eth0 port seems to be loop backed to the same team device".
I am working on a POC project, please share if you have any suggestions or pointers for me to setup a working LACP runner.
Thank you!

This isn't quite clear. Are you saying the "teamdctl team0 state" command shows the team running and LACP negotiated properly, then you set the team up again and the team virtual interface goes down?
Can you show the "teamdctl team0 state" command before running "ip link set up dev team0"?
Is your switch configured with a port group in LACP Fast mode?

Hi Jamie,
Thanks for your comments. The switch is borrowed from a colleague, not sure if it’s configured correctly. I will ask for admin access tomorrow and check the settings.
Best Regards, David
