From IOS, use the Network Map window to display information for any device
on the wireless network
. Unlike the
Association screen, the Network Map window does not list wired devices on the
LAN. From VxWorks, the same device information is displayed similarly
.
Network Map
Choose Enable or Disable for Network Map
capabilities. If Enable is selected, it is best to switch back to the Disable
default before leaving the page because the time to discover the network can
greatly increase the system load.
Network Map Table
-
MAC Address – The unique identifier assigned to the device by the
manufacturer.
-
IP Address – The IP address of the port.
-
Device – The type of device (client, access point, bridge, and so
on).
-
Name – The name given to this device.
From IOS, the Network Map>Adjacent AP List Page, all adjacent Cisco
APs can be viewed
. The AP Age
Timeout can be optionally set. This sets the amount of time the access point
will remain on the access point adjacent list before being removed for lack of
activity.
In IOS CLI, use the dot11 network-map global configuration
command to enable the radio network map feature. When enabled, the access point
broadcasts a IAPP GenInfo Request every collection interval. This request
solicits information from all Cisco access points in the same Layer 2 domain.
Upon receiving a GetInfo Request, the access point sends a unicast IAPP GenInfo
Response back to the requester. The access point uses these IAPP GenInfo
Responses to build a network-map. The command syntax is as follows:
dot11 network-map
[collect-interval]
The command example is as follows:
AP(config)#dot11 network-map
30
To display the radio network map, use the show
dot11 network-map privileged EXEC command. The radio network map contains
information from Cisco access points in the same Layer 2 domain as this access
point.
AP#show dot11 network-map
To
display a list of access points adjacent to a specific access point, use the
show dot11 adjacent-ap privileged EXEC command.
AP#show dot11 adjacent-ap

output of an adjacent access point list. The Adjacent AP List descriptions are
