Link Aggregation

The switch module supports Link Aggregation, or port trunking. Port trunks
(aggregated ports) can be used to increase the bandwidth of a network connection
or to ensure fault recovery.
You can configure up to two trunk connections (combining two to four ports into one
fat pipe) between any two BladeCenter switches or other Layer 2 switches.
However, before making any physical connections between devices, use the Link
Aggregation menus to specify the ports that will belong to the trunking group on
both switches.
