Installing and Configuring an Enterprise Mesh System
Default(config-ap)# parent-ap 3
Default(config-ap)# dataplane-encryption on
Default(config-ap)# end
Default)# reload ap 4
You can also configure these Enterprise Mesh parameters from the Web UI interface.
Check the Configuration Before Phase 3
Provisioning the wrong AP parameters can make the mesh backbone unable to recon-
nect. Also, it is difficult to debug a setup once the APs are in unreachable places.
Therefore, boot up the system multiple times in the staging configuration (all
connected to the wire in an installation room), until you are satisfied that the mesh
consistently comes up correctly. Before removing the AP wires, confirm that the APs
and the network are correctly configured by completing these tasks:
 Make Sure the APs are on the Network
You see a list of configured APs online when you issue the command show ap. Note
that each AP has two interface (IFIndex) entries, one for Ethernet and one for
wireless.
 Make Sure the Wireless APs Have Power
If an AP is getting power from a PoE and you disconnect the cable, you must
provide another power source.
 Check the AP Channels
Check the channels with the show interfaces Dot11Radio command. The results
look something like this example:
1 AP-1 1 AP180 Up Enabled 11 on802.11 Normal
1 AP-1 2 AP180 Up Enabled 44 off 802.11 Normal
2 AP-2 1 AP150 Up Enabled 11 on802.11 Normal
2 AP-2 2 AP150 Up Enabled 44 off802.11 Normal
3 AP-3 1 AP150 Up Enabled 11 on 802.11 Normal
3 AP-3 2 AP150 Up Enabled 44 off802.11 Normal
4 AP-4 1 AP150 Up Enabled 11 on 802.11 Normal
4 AP-4 2 AP150 Up Enabled 44 off802.11 Normal
Ensure that enabled APs (here AP-1, AP-2, AP-3 and AP-4) show the right channel
(44) for their IfIndex 2. If only two of APs are showing and you configured more,
you need to check your Enterprise Mesh licensing.
 Check the Topology and Dataplane-Encryption for Each AP
Check the Enterprise Mesh-tree after the APs are configured with the command
show ap-topology, which shows how the APs are connected to the controller:
Default# show ap-topology
|_AP-1(wds 00:12:F2:00:ce:29 ch 44)
|_|_AP-2 (wds 00:12:F2:00:cd:66 ch 44)
|_|_|_AP-3 (wds 00:12:F2:00:ce:35 ch 44)
|_|_|_|_AP-4 (wds 00:12:F2:00:cd:54 ch 44)
An Enterprise Mesh interface (wds) shows the radio addresses of the next-hop
forwarding and backhaul radio channel assignments.
