Background Scanning
When a Network Connect first connects to the network, it performs an initial scan of
available Wi-Fi channels and generates a list of potential alternative Client Connects
that are reachable. Following the initial scan, the Network Connect continually
scans in the background to maintain the inventory list and enable the system to
make the following intelligent decisions:
◗ When to drop the current path and select a better path, then connect to the
appropriate node (self-tuning).
◗ When to select the best path (or detect the loss of a path) and select the next
best path, then connect to the appropriate node (self-healing).
◗ Which APs are rogues.
Detecting Rogue Devices
A rogue device is any access point that the network doesn’t recognize. This can be a
third party AP that is not part of your Access/One Network or a valid network node
that has yet to be assigned.
Network Connects perform an active scan for rogue devices during every boot
sequence, and periodically thereafter. Alternatively, you can initiate a client scan
from Manager/One. When a rogue scan is started from Manager/One, all Client
Connects are placed in active scan mode, while Network Connects continue to
perform the background scan. Scans generally take between 10 and 20 seconds to
complete. Detected rogue devices are immediately reported to the network server
and the operator is alerted immediately. Rogue detection distinguishes between:
◗ Wired devices
◗ Wireless devices
◗ Wired and wireless devices (the most common culprit)
Rogue detection is achieved by triangulation, with Wi-Fi scanning performed by
selected Access/One Network elements. Rogue detection can affect the network
service because the system needs to scan all the available WiFi frequencies.
