Wireless Neighborhood
The Wireless Neighborhood shows all access points within range of every member of the cluster, shows which access points are within range of which cluster members, and distinguishes between cluster members and non-members.
 
Note: When accessing the Cluster - Wireless Neighborhood page, a maximum of 20 detected APs are reported per AP. To see all the detected APs, directly access the Neighboring Access Points page of the interested AP.
For each neighbor access point, the Wireless Neighborhood view shows identifying information (SSID or Network Name, IP Address, MAC address) along with radio statistics (signal strength, channel, beacon interval). You can click on an AP to get additional statistics about the APs in radio range of the currently selected AP.
The Wireless Neighborhood view can help you:
-
Detect and locate unexpected (or rogue) access points in a wireless domain so that you can take action to limit associated risks
-
-
The following table describes details about the Wireless Neighborhood information.
*
In cluster-Shows only neighbor APs that are members of the cluster
*
Not in cluster-Shows only neighbor APs that are not cluster members
*
Both-Shows all neighbor APs (cluster members and non-members)
An access point which is detected as a neighbor of a cluster member can also be a cluster member itself. Neighbors who are also cluster members are always shown at the top of the list with a heavy bar above and include a location indicator.
The colored bars to the right of each AP in the Neighbors list shows the signal strength for each of the neighbor APs as detected by the cluster member whose IP address is shown at the top of the column.
*
Dark Blue Bar-A dark blue bar and a high signal strength number (for example 50) indicates good signal strength detected from the Neighbor seen by the AP whose IP address is listed above that column.
*
Lighter Blue Bar-A lighter blue bar and a lower signal strength number (for example 20 or lower) indicates medium or weak signal strength from the Neighbor seen by the AP whose IP address is listed above that column
*
White Bar-A white bar and the number 0 indicates that a neighboring AP that was detected by one of the cluster members cannot be detected by the AP whose IP address if listed above that column.
*
Light Gray Bar-A light gray bar and no signal strength number indicates a Neighbor that is detected by other cluster members but not by the AP whose IP address is listed above that column.
*
Dark Gray Bar-A dark gray bar and no signal strength number indicates this is the AP whose IP address is listed above that column (since it is not applicable to show how well the AP can detect itself).
Viewing Details for a Cluster Member
To view details on a cluster member AP, click on the IP address of a cluster member at the top of the page.
The following table explains the details shown about the selected AP.
The Service Set Identifier (SSID) for the access point.
The SSID is an alphanumeric string of up to 32 characters that uniquely identifies a wireless local area network. It is also referred to as the Network Name.
Beacon frames are transmitted by an access point at regular intervals to announce the existence of the wireless network. The default behavior is to send a beacon frame once every 100 milliseconds (or 10 per second).
