Status Rogue AP Detection 2 Link Integrity Monitoring The access point provides link integrity monitoring to continually verify its connection to each associated client. To do this, the access point sends data packets to clients every few seconds when no other traffic is passing. This allows the access point to detect when a client goes out of range, even during periods when no normal traffic is exchanged. The client connection drops off the list within 300 seconds if these data packets are not acknowledged, even if no disassociation message is received. Rogue AP Detection A Rogue AP is an access point that has been installed on a secure network without authorization from a system administrator. Rogue access points pose a security threat because anyone with access to the premises can ignorantly or maliciously install a wireless access point that might allow unauthorized parties to access the network. The Rogue AP Detection page displays information about all access points detected by the Cisco AP 541N in the vicinity of the network. If the access point listed as a rogue is actually a legitimate access point, you can add it to the Known AP List. Click Refresh to refresh the page. NOTE The Detected Rouge AP List and Known AP List provide information. The Cisco AP 541N does not have any control over the access points on the lists and cannot apply any security policies to access points detected through the RF scan.
