Setting Mesh Uplinks Manually
In a wireless mesh network, the default behavior of Mesh APs is to connect automatically to a mesh node
(either Mesh AP or Root AP) that provides the highest throughput. This automatic connection is called Smart
Uplink Selection.
If you want to shape your mesh network or force a certain topology, you will need to disable Smart Uplink
Selection and manually set the mesh nodes to which an AP can connect. Note that in most situations, Manually
changing the roles of APs in a mesh is not recommended, because it can result in isolated Mesh APs.
To set the mesh uplink for an AP manually:
1.
From the Browser-Based Configuration Pages, select Configure > Access Points (page 66).
2.
In the Access Points table, find the AP you want to restrict, and click Edit under the Actions column. The
editing form appears below your selection.
3.
Under Advanced Options > Uplink Selection, select the Manual radio button. The other APs in the
mesh appear below the selection.
4.
Select the check box for each AP that the current AP can use as uplink.
5.
Click OK to save your settings.
Troubleshooting Isolated Mesh APs
Isolated Mesh APs are those that were once managed by the NXA-WAPZD1000 but are now unreachable.
They are up and running and constantly searching for mesh uplinks, but are unable to connect to any root AP.
You can check if you have any isolated mesh APs on the network by checking the Monitor > Access Points
page.
Action Icons (Cont.)
Restart
Initiate a reboot of this AP.
Recover
Recover an isolated Mesh AP.
Allow
Allow this AP to be managed by the NXA-WAPZD1000. This icon will only
appear if you have disabled automatic approval under “Access Point
Policies” on the
Configure > Access Points
page.
RF Info
Generates a log file called info.txt, containing radio frequency data that can
be used for troubleshooting the RF environment.
Do not manually set a Mesh AP as a Root AP. Only APs that are connected to the
NXA-WAPZD1000 via Ethernet (and on the same LAN segment) should be
configured as Root APs. Misconfiguring a Mesh AP or an eMAP as a Root AP can
cause the AP to become isolated, or, in the case of eMAP, can result in a network
loop.
If you set Uplink Selection for an AP to
Manual
and the uplink AP that you selected is
off or unavailable, the AP status on the
Monitor > Access Points
page will appear
as Isolated Mesh AP.
A mesh network is dynamic in nature. Before attempting to resolve any mesh-related
issue, please wait 15 minutes to allow the mesh network to stabilize. Some mesh
related issues are automatically resolved once the mesh network stabilizes.
