Which approach is used to determine if an on wire rogue AP exists and is active?

Rogue Location Detection Protocol (RLDP) is a Cisco wireless feature where an AP, acting as a monitor, can send specific packets to a suspected rogue AP and then monitor the wired network for a response, confirming if the rogue is indeed connected to the network infrastructure. This process verifies an 'on wire' rogue AP's active status by tracing its connection to the wired network.

UDP (User Datagram Protocol) is a connectionless transport layer protocol, not a specific mechanism for detecting on-wire rogue APs.

DTLS (Datagram Transport Layer Security) is a protocol that provides communications security for datagram-based applications, not a method for rogue AP detection.

RSSI (Received Signal Strength Indicator) measures the strength of a wireless signal, which can identify the presence of a rogue AP but does not determine if it is actively connected to the wired infrastructure.
