Configuring an LACP Timeout

In a dynamic or keep-alive LAG, a port timeout can be configured as short (3 seconds) or long (90 seconds). After you configure the port timeout, the port remains in that timeout mode regardless of whether it is up or down.

All the ports in a LAG must have the same timeout mode. This requirement is checked when the LAG is enabled on the ports.

Complete the following steps to configure a port for a short LACP timeout.

Enter the global configuration mode.
```
device# configure terminal
```

Create a dynamic LAG.
```
device(config)# lag blue dynamic id 1
```

Add ports to the LAG.

device(config-lag-blue)# ports ethernet 1/3/1 ethernet 1/3/2

Configure the timeout mode for the port.
```
device(config-lag-blue)# lacp-timeout short
```

The following example configures a port for a short LACP timeout.

device(config)# lag blue dynamic id 1
device(config-lag-blue)# lacp-timeout short
LAG blue un-deployed successfully!
LAG blue deployed successfully!
device(config-lag-blue)#
