The Rate Limit
Excessive traffic can cause performance issues or bring down the network completely. Excessive traffic can be caused by
numerous sources including network loops, faulty devices or malicious software such as a worm or virus that has infected
on one or more devices at the branch. Rate limiting limits the maximum rate sent to or received from the wireless network
(and mesh point) per neighbor. It prevents any single user from overwhelming the wireless network. It can also provide
differential service for service providers. An administrator can set separate QoS rate limit configurations for data
transmitted from the managed network and data transmitted from a mesh point's neighbor back to their associated access
point radios and controller.
Before defining rate limit thresholds for mesh point transmit and receive traffic, Motorola Solutions recommends you define
the normal number of ARP, broadcast, multicast and unknown unicast packets that typically transmit and receive from each
supported WMM access category. If thresholds are defined too low, normal network traffic (required by end-user devices)
will be dropped resulting in intermittent outages and performance problems.
A connected neighbor can also have QoS rate limit settings defined in both the transmit and receive direction.
Displays whether or not a Mesh Rx Rate Limit is enabled for each Mesh QoS policy. This
indicates rate limiting is enabled or disabled for all data transmitted by the device to any
mesh point in the mesh. When the rate limit is enabled a green check mark is displayed,
when it is disabled a red X is displayed.
Displays whether a NeighborTx Rate Limit is enabled for each Mesh QoS policy. This
indicates rate limiting is enabled for data transmitted from connected wireless clients.
When the rate limit is enabled a green check mark is displayed, when it is disabled a red
X is displayed.
Displays whether a NeighborRx Rate Limit is enabled for each Mesh QoS policy. This
indicates rate limiting is enabled or disabled for data transmitted from the client to its
associated access point radio and connected wireless controller. When the rate limit is
enabled a green check mark is displayed, when it is disabled a red X is displayed.
Displays the forwarding QoS classification for each Mesh QoS policy.
