If a wireless controller uses LAG to the switch, which EtherChannel mode must the switch use for the WLC to connect?

Correct answer: On.
Why this is the answer
When a wireless LAN controller (WLC) is configured to use Link Aggregation Group (LAG), it operates in a static EtherChannel mode. This means the WLC does not negotiate EtherChannel with the connected switch. Therefore, the switch port or port-channel interface connected to the WLC must also be configured in a static EtherChannel mode, which is "on." On: This mode forces the interface into an EtherChannel without negotiation, matching the WLC's static LAG behavior. Active: This mode uses LACP to actively negotiate EtherChannel. The WLC does not support LACP. Passive: This mode uses LACP to passively negotiate EtherChannel. The WLC does not support LACP. Auto: This mode uses PAgP to passively negotiate EtherChannel. The WLC does not support PAgP.
