15.2 What You Can Do in the Rogue AP Screen
• Use the Rogue AP > Configuration screen (see
to enable your NWA’s Rogue AP detection settings. You can choose to scan for
rogue APs manually, or to have the NWA scan automatically at pre-defined
intervals.
• Use the Rogue AP > Friendly AP screen (see
) to
specify APs as trusted.
• Use the Rogue AP > Rogue AP screen (see
) to
display details of all IEEE 802.11a/b/g wireless access points within the NWA’s
coverage area, except for the NWA itself and the access points included in the
friendly AP list.
15.3 What You Need To Know
You can configure the NWA to detect rogue IEEE 802.11a (5 GHz) and IEEE
802.11b/g (2.4 GHz) APs.

Friendly APs
If you have more than one AP in your wireless network, you must also configure
the list of “friendly” APs. Friendly APs are other wireless access points, aside from
the NWA, that are detected in your network, as well as any others that you know
are not a threat (those from neighboring networks, for example). It is
recommended that you export (save) your list of friendly APs often, especially if
you have a network with a large number of access points. If you do not add them
to the friendly AP list, these access points will appear in the Rogue AP list each
time the NWA scans.
