A customer requires that the remote site be able to utilize local servers when the AP is in WAN- down (standalone mode). Which AP mode must be configured on the wireless controller?

SE-Connect mode dedicates the AP to spectrum analysis via Cisco Spectrum Expert and cannot serve wireless clients.

Monitor mode is a passive scanning mode used for rogue detection and interference analysis and does not support client associations or data forwarding.

Local mode requires a continuous CAPWAP tunnel to the WLC for all client data, so connectivity is lost entirely when the WAN link goes down.

FlexConnect is specifically designed for remote and branch office deployments where WAN reliability cannot be guaranteed. When the WAN link fails, a FlexConnect AP operating in standalone mode continues to authenticate clients locally and forwards data directly to local VLANs and servers without requiring an active CAPWAP tunnel to the WLC, satisfying the requirement for local server access during WAN outages.

Sniffer mode captures 802.11 frames and forwards them to a packet analyzer and does not allow client connectivity or local data switching.

Rogue Detector mode correlates wired ARP data with wireless scans to identify rogue devices and does not serve client data traffic.
