Mesh networking frequently asked questions
9
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?
Resolution
Yes, MUs on a mesh APs can roam seemlessly throughout the mesh network as well as with
non-mesh access points on the wired network.
Mesh Deployment Issue 8 - Can I update firmware/configuration files across a mesh backhaul?
Can I update device firmware over the mesh backhaul on a client bridge or repeater AP with no
wired connectivity?
Resolution
Yes, a Brocade Mobility 7131N-FGR Access Point support wireless firmware updates.
Mesh Deployment Issue 9 - Can I perform firmware/configuration file updates with DHCP options?
Can I use the AP’s Automatic Firmware/Configuration update functionalities with DHCP Options on
the AP for mesh nodes as well?
Resolution
Yes, mesh nodes also support Automatic Firmware/Configuration updates using DHCP Options.
Make sure you create DHCP reservations for each mesh node and add an appropriate
configuration file to each one of them. If you don’t, the base bridge configuration file could get
applied on a client bridge or repeater and you will loose connectivity to that AP.
Mesh Deployment Issue 10 - Why do I lose connectivity when updating configurations?
When I make a configuration change and apply the changes on a client bridge or repeater, I
momentarily loose connectivity to that AP, why?
Resolution
That is expected behavior, when you make a configuration change on a mesh supported AP, it
brings the radio driver down and then back up again. Consequently, the AP needs to re-establish its
mesh connection after saving the configuration.
Mesh Deployment Issue 11 - Will an existing client bridge see a new base bridge or repeater?
If I add a new base bridge or repeater to an existing mesh topology, will my current client bridges
see it and connect to it?
Resolution
Yes, all client bridges perform periodic background scanning - both passively (by sniffing the air for
beacons) and actively (by sending Probe Requests). Therefore, a client bridge automatically detects
the presence of a new base bridge or repeater added to the mesh network topology and forms a
seam less connection without affecting current operation.
