To configure a static LAG, enter the following commands:
FastIron(config)#trunk e 1/5 to 1/8
trunk will be created in next trunk deploy
FastIron(config)#write memory
FastIron(config)#trunk deploy
Dynamic Link Aggregation (802.1ad)
Brocade software supports the IEEE 802.3ad standard for link aggregation. This standard describes the Link
Aggregation Control Protocol (LACP), a mechanism for allowing ports on both sides of a redundant link to form a LAG
link (aggregate link), without the need for manual configuration of the ports into LAG groups.
When you enable link aggregation on a group of Brocade ports, the Brocade ports can negotiate with the ports at the
remote ends of the links to establish LAG groups.
The link aggregation feature automates LAG configuration but can coexist with the Brocade LAG group feature. Link
aggregation parameters do not interfere with LAG group parameters.
Link aggregation support is disabled by default. You can enable the feature on an individual port basis, in active or
passive mode:
• Active mode. When you enable a port for active link aggregation, the Brocade port can exchange
standard LACP Data Unit (LACPDU) messages to negotiate LAG group configuration with the port on the
other side of the link. In addition, the Brocade port actively sends LACPDU messages on the link to
search for a link aggregation partner at the other end of the link, and it can initiate an LACPDU
exchange to negotiate link aggregation parameters with an appropriately configured remote port.
• Passive mode. When you enable a port for passive link aggregation, the Brocade port can exchange
LACPDU messages with the port at the remote end of the link, but the Brocade port cannot search for a
link aggregation port or initiate negotiation of an aggregate link. Thus, the port at the remote end of the
link must initiate the LACPDU exchange.
To configure a dynamic LAG using default keys assigned by software:
FastIron(config)#interface ethernet 1/1
FastIron(config-if-e1000-1/1)#link-aggregate active
FastIron(config)#interface ethernet 1/2
FastIron(config-if-e1000-1/2)#link-aggregate active
To configure a dynamic LAG using an assigned unique key:
FastIron(config)#interface ethernet 1/1
FastIron(config-if-e1000-1/1)#link-aggregate active
FastIron(config)#interface ethernet 1/2
FastIron(config-if-e1000-1/2)#link-aggregate active
