• clear lacp counters

• debug lacp

• delay-restore abort-threshold

• io-aggregator auto-lag enable

• lacp link-fallback

• lacp long-timeout

• lacp port-priority

auto-lag enable

Enable auto-lag on a server facing port.

When disabled, the server port associated in a LAG is removed and the LAG itself gets removed. Any LACPDUs

received on the server port are discarded.
