Multiple LAG Interface Support
Extreme Campus Controller supports redundant configurations where the appliance provides
connectivity to two switch stacks for one port function. On the L2 Ports pane, you can configure
Extreme Campus Controller attachment through a LAG to one switch, or attached to two separate
switch stacks, forming a Multiple Link Aggregation Group (MLAG). An MLAG joins two or more
interfaces in the same Link Aggregation Group.
Note
Multiple Link Aggregation Group (MLAG) is supported on hardware appliances E1120, E2120,
E2122, and E3120. MLAG is not supported on Extreme Campus Controller virtual appliances
(VMware or HyperV based platforms).
Note
LAG groups are restricted to ports of the same type (speed).
