Which EtherChannel mode must be configured when using LAG on a WLC?
When a Cisco WLC uses LAG, the bundled uplinks must be configured as a static EtherChannel rather than a negotiated one. Cisco documentation states that LAG requires the EtherChannel to be set to mode on on both the controller and the switch, not LACP (active/passive) or PAgP (auto).
