Is the Link Aggregation (LAG) feature supported with the Cisco WiSM?
A. LAG bundles all of the distribution ports of a controller into a single EtherChannel. This reduces the number of AP Manager Interfaces required for full AP capacity. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user. LAG is enabled automatically on the Cisco WiSM controllers. Without LAG, each distribution system port on the controller supports up to 48 access points. With LAG enabled, the logical port on each Cisco WiSM controller supports up to 150 access points. LAG simplifies the controller configuration because you no longer need to configure primary and secondary ports for each interface. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. As long as one controller port functions, the system continues to operate, access points remain connected to the network, and wireless clients continue to send and receive data.
