Configuring the LACP timeout period

The LACP timeout period indicates how long LACP waits before timing out the neighboring device.

The short timeout period is 3 seconds and the long timeout period is 90 seconds. The default is long. The short timeout period specifies that the PDU is sent every second and the port waits three times this long (three seconds) before invalidating the information received earlier on this PDU. The long timeout period specifies that the PDU is sent once in 30 seconds and the port waits three times this long (90 seconds) before invalidating the information received earlier on this PDU.

To configure the LACP timeout period on an interface, perform the following steps:

  1. Enter the configure terminal command to access global configuration mode.
  2. Enter the interface command, specifying the interface type and the slot/port.
    device(config)# interface ethernet 0/1 
  3. Enter the no shutdown command to enable the interface.
  4. Specify the LACP timeout short period for the interface.
    device(conf-if-eth 0/1)# lacp timeout short 
  5. Specify the LACP timeout long period for the interface.
    device(conf-if-eth 0/1)# lacp timeout long
