Verifying Mesh Network Functionality for Scenario #2
You now have a three AP demo multi-hop mesh network ready to demonstrate. Associate
an MU on the WLANs configured on the 802.11b/g/n radio for each AP and pass traffic
among the members of the mesh network.
Mesh Networking Frequently Asked Questions
The following scenarios represent issues that could be encountered and resolved when defining an
access point supported mesh configuration:
Mesh Deployment Issue 1 - Client Bridge can only connect to one of two Base Bridges
You have two access points configured as base bridges (AP1, AP2) and one access point defined as
a as a client bridge (AP3). However, the client bridge is able to connect to only one of the base
bridges.
Resolution
Check the mesh backhaul radio channel configuration on both base bridges (AP1, AP2). They need
to use the same channel so the client bridge can connect to both simultaneously.
Mesh Deployment Issue 2 - Faulty Client Bridge Connectivity
You have configured three access points in mesh mode; one base bridge (AP1), one client
bridge/base bridge (AP2) and one client bridge (AP3). However, the client bridge (AP3) is
connecting to both AP1 and AP2 and using its link to base bridge (AP1) to forward traffic.
Resolution
This is valid behavior, you see this when your mesh APs are close enough (in proximity) so the client
bridge can see both the base bridges (AP1, AP2), in which case it forms two links, one each to AP1
and AP2. Since the link to AP1 is the shortest path in terms of number of hops, AP3 uses that link
to forward traffic.
Mesh Deployment Issue 3 - Cannot select a WLAN name for a Client Bridge
You created a WLAN for mesh backhaul on an AP needed as a client bridge, but you don't get to
select the WLAN name in the Mesh Network Name drop down menu. Why?
Resolution
Check the WLAN configuration to ensure you have enabled the Enable Client Bridge Backhaul
option.
Mesh Deployment Issue 4 - Do I need to map a WLAN to a radio when configuring mesh backhaul
on a Client Bridge?
When creating a mesh backhaul WLAN on a client bridge only AP, do you need to map the WLAN on
a radio?
Resolution
No, a client bridge only AP behaves just like an MU! It scans for base bridges and forms
connections to them. It doesn't need to beacon on that WLAN. Therefore, while creating a mesh
backhaul WLAN on a client bridge only AP, just enable the Enable Client Bridge Backhaul option.
