Managing Rogue Access Points
A rogue AP is an access point that connects to the wireless network without authorization. In some
cases, the AP may be performing a legitimate function and the appropriate management action is to
classify the AP as “known.” If it is not possible to identify a legitimate role for the AP, then the AP
is considered to be a true rogue. NM Portal provides information to help determine where rogue
APs are physically located and how recently they have accessed the network. With this
information, it may be possible to find and disable them.
Potential rogue AP candidates are identified during discovery. Every 15 minutes, NM Portal scans
the network to discover and identify known Airgo APs. The domain for the discovery process is
specified in the Discovery Configuration panel (see “Configuring Network Discovery” on
page 200). Discovery can be restricted to specific subnetworks, ranges of IP addresses, or
individual APs. It is also possible to specify whether the discovery is at the IP (Layer-3) or
wireless/MAC level (layer 2).
Wireless discovery is based on the beacon sent by APs within range of the receiving AP. Each AP
collects information about beacons it sees and passes that information to NM Portal. NM Portal
checks the MAC address of the detected AP to see whether it matches that of a known AP. If it does
not match, the detected AP becomes a rogue AP candidate.
