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.
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.
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.
