To add additional interfaces to an existing LAG, repeat this procedure using the same LAG group
number for the new interfaces.
Enter the copy running-config startup-config command to save your configuration.
To enable LACP on a DCB interface, perform the following step:.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the DCB interface type and slot/port number.
NOTE
The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710. The prompt
for these ports is in the format: switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/1
3. Enter the no shutdown command to enable the DCB interface.
4. Enter the channel-group command to configure the LACP for the DCB interface.
switch(conf-if)# channel-group 4 mode active type standard
Configuring the LACP system priority
The switch must be in privileged EXEC mode.
You configure the 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:
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 DCB interface
The switch must be in privileged EXEC mode.
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 Data Center Bridging (DCB) interface, perform the following
steps:
1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the DCB interface type and slot/port number.
NOTE
The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710, VDX
8770-4, and VDX 8770-8 switches. The prompt for these ports is in the format: switch(config-if-
gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/1
3. Enter the no shutdown command to enable the DCB interface.
4. Specify the LACP timeout period for the DCB interface.
switch(conf-if-te-0/1)# lacp timeout short
