4. Configure the following parameters in respect to the intended From Air Upstream Rate Limit, or
traffic from the controller to associated Access Point radios and their associated neighbor:
Mesh Tx Rate Limit Select the check box to enable rate limiting for all data received from any mesh point in the mesh
network. This feature is disabled by default.
Rate Define a receive rate limit between 50 - 1,000,000 kbps. This limit constitutes a threshold for the
maximum the number of packets transmitted or received over the mesh point (from all access
categories). Traffic that exceeds the defined rate is dropped and a log message is generated. The
default setting is 5000 kbps.
Maximum Burst Size Set a maximum burst size between 2 - 1024 kbytes. The smaller the burst, the less likely the
transmit packet transmission will result in congestion for the mesh point’s client destinations. By
trending the typical number of ARP, broadcast, multicast and unknown unicast packets over a
period of time, the average rate for each access category can be obtained. Once a baseline is
obtained, administrators should then add a 10% margin (minimally) to allow for traffic bursts at the
site. The default burst size is 320 kbytes.
