Local mesh
Quality of service

Operating channel
If a mesh operates on a dynamic frequency selection (DFS) channel, the master node selects
the operating channel. If another node detects radar and switches channels, that node reports
the channel switch to the master node, which initiates a channel switch for the nodes
connected to it. This allows the local mesh to converge on a specific channel.
A node that uses a DFS channel and that loses connection with its master, scans channels to
find a master on another channel, which can be a new master or the same master .
If the local mesh does not operate on a DFS channel, configure the radios in one of the
following ways:
 Configure the radios on all nodes to use the same fixed channel.
 Configure the radios for automatic channel selection. In this case the master selects the
least noisy channel. Slaves and alternate masters scan channels until they find the master,
then tune to the master channel and link with the master .
Configuration guidelines
 You can configure a total of six local mesh profiles on each node.
 Each dynamic local mesh profile (master or alternate master) can be used to establish up
to nine links with other nodes.
 The same security settings must be used on all nodes in the same mesh.
Quality of service
The local mesh feature enables you to define a quality of service (QoS) setting that will
govern how traffic is sent on all wireless links.
Note
When traffic is forwarded onto a local mesh link from a VSC, the QoS settings on the VSC
take priority. For example, if you define a VSC with a QoS setting of VSC-based High , then
traffic from this VSC will traverse the local mesh on queue 2 even if the QoS setting on the
local mesh is VSC-based Low (queue 4).
