Unable to get LACP runner working

[davidchen7]

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. Please share if you have any suggestions or pointers.

Thank you!

Maybe you need to check the configurations of the neighbor and use the tcpdump to check the LACP packets. With the given information, it is hard to tell if the neighbor's LAG is configured correctly.

Thank you for the suggestion Shuotian! I will investigate more.
