Connecting the Cisco 1520 Series Mesh Access Point to Your Network
• To view the mesh tree topology for the network and the bandwidth utilization (used/maximum
available) of voice calls and video links for each mesh access point and radio, enter this command:
show mesh cac bwused {voice | video} AP_name
Information similar to the following appears:
AP Name Slot# Radio BW Used/Max
------------- ------- ----- -----------
SB_RAP1 0 11b/g 1016/23437
1 11a 3048/23437
|SB_MAP1 0 11b/g 0/23437
1 11a 3048/23437
|| SB_MAP2 0 11b/g 2032/23437
1 11a 3048/23437
||| SB_MAP3 0 11b/g 0/23437
1 11a 0/23437
Note The bars (|) to the left of the AP Name field indicate the number of hops that the MAP is
from its RAP.
Note When the radio type is the same, the backhaul bandwidth utilization (bw used/max) at each
hop is identical. For example, mesh access points map1, map2, map3, and rap1 are all on
the same radio backhaul (802.11a) and are using the same bandwidth (3048). All of the calls
are in the same interference domain. A call placed anywhere in that domain affects the
others.
• To view the mesh tree topology for the network and display the number of voice calls that are in
progress by mesh access point radio, enter this command:
show mesh cac access AP_name
Information similar to the following appears:
AP Name Slot# Radio Calls
------------- ------- ----- -----
SB_RAP1 0 11b/g 0
1 11a 0
| SB_MAP1 0 11b/g 0
1 11a 0
|| SB_MAP2 0 11b/g 1
1 11a 0
||| SB_MAP3 0 11b/g 0
1 11a 0
Note Each call received by a mesh access point radio causes the appropriate calls summary
column to increment by one. For example, if a call is received on the 802.11b/g radio on
map2, then a value of one is added to the existing value in that radio’s calls column. In this
case, the new call is the only active call on the 802.11b/g radio of map2. If one call is active
when a new call is received, the resulting value is two.
