Dynamic link aggregation
IronStack LACP trunk group configuration example
To configure a trunk group consisting of two groups of two ports each on an IronStack, enter
commands similar to the following.
Brocade(config)#interface ethernet 1/1/1 to 1/1/4
Brocade(config-mif-1/1/1-1/1/4)#link-aggregate off
Brocade(config-mif-1/1/1-1/1/4)#link-aggregate configure key 10000
Brocade(config-mif-1/1/1-1/1/4)#link-aggregate active
Brocade(config-mif-1/1/1-1/1/4)#interface ethernet 3/1/5 to 3/1/8
Brocade(config-mif-3/1/5-3/1/8)#link-aggregate off
Brocade(config-mif-3/1/5-3/1/8)#link-aggregate configure key 10000
Brocade(config-mif-3/1/5-3/1/8)#link-aggregate active
This command sequence changes the key for ports 1/1/1 through 1/1/4 and 3/1/5 through
3/1/8 to 10000. Because all ports in an aggregate link must have the same key, this example
forms a multi-slot aggregate link for ports 1/1/1 through 1/1/4 and 3/1/5 through 3/1/8.
Examples of valid LACP trunk groups
Brocade ports follow the same configuration rules for dynamically created aggregate links as they
do for statically configured trunk groups. Refer to “Trunk group rules” on page 699 and “Trunk
group load sharing” on page 705.
Figure 67 shows some examples of valid aggregate links.
