Wireless Neighborhood
The Wireless Neighborhood page shows up to 20 devices per radio within range of each wireless radio in the cluster. (For example, if a WAP device has two wireless radios, 40 devices would be displayed for that device.) The Wireless Neighborhood page also distinguishes between cluster members and nonmembers.
The Wireless Neighborhood view can help you:
- Detect and locate unexpected (or rogue) devices in a wireless domain so that you can take action to limit associated risks.
- Verify coverage expectations. By assessing which WAP devices are visible and at what signal strength from other devices, you can verify that the deployment meets your planning goals.
- Detect faults. Unexpected changes in the coverage pattern are evident at a glance in the color coded table.
To view neighboring devices, select Single Point Setup > Wireless Neighborhood in the navigation pane. To see all the devices detected on a given Single Point Setup, navigate to the web interface of a member and select Wireless > Rogue AP Detection in the navigation pane.
For each neighbor access point, the following information is shown:
- Display Neighboring APs—Select one of the following radio buttons to change the view:
NOTE For a detected AP that is also a cluster member, only the SSIDs of the default VAP (VAP0) are displayed as In cluster. Non default VAPs on the AP are displayed as Not in cluster.
- Cluster—The list at the top of the table shows IP addresses for all WAP devices that are clustered together. (This list is the same as the members list on the Single Point Setup > Access Points page.)
If there is only one WAP device in the cluster, only a single IP address column shows, indicating that the WAP device is grouped with itself.
You can click on an IP address to view more details on a particular WAP device.
- Neighbors—Devices that are neighbors of one or more of the clustered devices are listed in the left column by SSID (network name).
A device that is detected as neighbor 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 WAP device in the Neighbors list shows the signal strength for each of the neighbor WAP devices, as detected by the cluster member whose IP address is shown at the top of the column.
The color of the bar indicates the signal strength:
- Dark Blue Bar—A dark blue bar and a high signal strength number (for example, 50) indicates good signal strength detected from the neighbor, as seen by the device 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, as seen by the device whose IP address is listed above that column
- White Bar—A white bar and the number 0 indicates that a neighboring device that was detected by one of the cluster members cannot be detected by the device whose IP address is listed above that column.
- Light Gray Bar—A light gray bar and no signal strength number indicates that no signal has been detected from the neighbor, but the neighbor may have been detected by other members of the cluster.
- Dark Gray Bar—A dark gray bar and no signal strength number indicates the WAP device itself that corresponds to the IP address listed above it. A signal strength of zero is displayed because the device’s own signal strength is not measured.
Viewing Details for a Single Point Setup Member
To view details on a cluster member, click the IP address of a member at the top of the page.
The following details for the device appear below the Neighbors list.
- SSID—The Service Set Identifier for the neighboring access point.
- MAC Address—The MAC address of the neighboring access point.
- Channel—The channel on which the access point is currently broadcasting.
- Rate—The rate in megabits per second at which this access point is currently transmitting. The current rate is always one of the rates shown in Supported Rates.
- Signal—The strength of the radio signal detected from the access point, measured in decibels (dB).
- Beacon Interval—The beacon interval used by the access point.
- Beacon Age—The date and time of the last beacon received from this access point.
