Topics:
• auto-lag enable
• clear lacp counters
• debug lacp
• io-aggregator auto-lag enable
• lacp link-fallback member
• lacp long-timeout
• lacp port-priority
• port-channel mode
• port-channel-protocol lacp

auto-lag enable
Enable auto-lag on a server facing port.
Syntax
auto-lag enable

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.
