Brocade Communications Systems 53-1002163-02 manual Enabling Lacp on an interface in Layer 2 mode

8 LACP configuration and management

To enable LACP 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 tengigabitethernet 0/1

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

switch(config-if)#no shutdown

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

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

Enabling LACP on an interface in Layer 2 mode

To enable LACP on a Layer 2 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 interface port-channel.

switch(config)#interface port-channel 4

3. Enter the switchport command to set the interface into Layer 2 mode.

switch(conf-if-po-4)#switchport

4. Enter the switchport mode command to set the mode.

switch(conf-if-po-4)#switchport mode access

5. Enter the no shutdown command to enable the interface.

switch(config-if)#no shutdown

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.
