Configuring Mesh Networking
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.
Mesh Deployment Issue 5 - Do I need to use secure beacons on a mesh backhaul supported WLAN?
Can I use secure beacons on the mesh backhaul supported WLAN?
Resolution:
Yes, you can enable a secure beacon on a mesh backhaul supported WLAN. In fact, it is a Extreme
Networks recommended practice.
Mesh Deployment Issue 6 - Is my mesh topology complete?
How can I determine if all my mesh APs are connected and the mesh topology is complete?
Resolution:
Each mesh AP has a Known AP Table (available in the applet, CLI and SNMP). All APs (whether they
are supporting mesh or not) periodically exchange ID messages notifying their presence to one
another. Review the Known AP Table on any mesh supported AP to determine if you have all
required APs connected to the mesh topology.
Mesh Deployment Issue 7 - Can MUs roam within a mesh topology?
Can MUs connected to a mesh AP roam seemlessly among other MUs and wired Access Points?
