3.Enter the no shutdown command to enable the CEE interface.

4.Enter the channel-groupcommand to configure the LACP for the CEE interface.

switch(conf-if)#channel-group 4 mode active type Dell

Configuring the LACP system priority

You configure an LACP system priority on each switch running LACP. LACP uses the system priority with the switch MAC address to form the system ID and also during negotiation with other switches.

The system priority value must be a number in the range of 1 through 65535. The higher the number, the lower the priority. The default priority is 32768.

To configure the global LACP system priority, perform the following steps from Privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Specify the LACP system priority.

switch(config)#lacp system-priority 25000

Configuring the LACP timeout period on a CEE interface

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.

To configure the LACP timeout period on a CEE interface, perform the following steps from Privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter the interface command to specify the CEE interface type and slot/port number.

switch(config)#interface intengigabitethernet 0/1

3.Enter the no shutdown command to enable the CEE interface.

4.Specify the LACP timeout period for the CEE interface.

switch(conf-if-te-0/1)#lacp timeout short

Configuring minimum links feature

The minimum links feature allows a port-channel to operate at a certain minimum bandwidth all the time. If the bandwidth of the port-channel drops below that minimum number, then the port-channel is declared operationally DOWN even though it has operationally UP members.

For example, if a port-channel has five members, each with 10 Gigabit bandwidth and you want the port-channel to have a minimum bandwidth of 30 Gigabit, then the port-channel is declared operationally UP only when there are at least three members operationally UP in it. As soon as the operational members falls below three, the port-channel is declared operationally DOWN.

To configure this feature, perform the following steps under global configuration mode.

1. Select the interface.

switch(config)#interface intengigabitethernet 0/1
