Overview of link aggregation

This chapter describes how to configure Link Aggregation Groups (LAG). Beginning with FastIron 08.0.00a, you can use a single interface to configure any of the following LAG types:

Static LAGs - These LAGs are manually-configured aggregate links containing multiple ports.

Dynamic LAGs - This LAG type uses the Link Aggregation Control Protocol (LACP), to maintain aggregate links over multiple port. LACP PDUs are exchanged between ports on each device to determine if the connection is still active. The LAG then shuts down ports whose connection is no longer active.

Keep Alive LAGs - In a Keep Alive LAG a single connection between a single port on 2 Ruckus devices is established. In a keep alive LAG, LACP PDUs are exchanged between the 2 ports to determine if the connection between the devices is still active. If it is determined that the connection is no longer active, the ports are blocked.

The new LAG configuration procedures supersede the previous configurations procedures for LAGs and Dynamic Link Aggregation. When a Ruckus device is upgraded to 08.0.00a any configurations for LAGs or Dynamic Link Aggregation defined in releases prior to 08.0.00a will be converted to a 08.0.00a (and later) compatible LAG configuration.
