Rates
Protocol data units (PDUs) are exchanged between port-channel (LAG) interfaces to maintain LACP sessions. PDUs are transmitted at
either a slow or fast transmission rate, depending on the LACP timeout value. The timeout value is the amount of time that a LAG interface
waits for a PDU from the remote system before bringing the LACP session down.
By default, the LACP rate is normal (long timeout). If you congure a fast LACP rate, a short timeout sets.
• Set the LACP rate in CONFIGURATION mode.
