Auto-Congured LACP Timeout
LACP PDUs are exchanged between port channel (LAG) interfaces to maintain LACP sessions. LACP PDUs are transmitted at a slow or
fast transmission rate, depending on the LACP timeout value congured on the partner system.
The timeout value is the amount of time that a LAG interface waits for a PDU from the partner system before bringing the LACP session
down. The default timeout is long-timeout (30 seconds) and is not user-congurable on the Aggregator.
LACP Example
The below illustration shows how the LACP operates in an Aggregator stack by auto-conguring the uplink LAG 128 for the connection to a
top of rack (ToR) switch and a server-facing LAG for the connection to an installed server that you congured for LACP-based NIC
teaming.
