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.
