A connected neighbor can also have QoS rate limit settings defined in both the transmit and
receive direction.
Supported in the following platforms:
• Access Points — Brocade Mobility 1220 Access Point, Brocade Mobility 71XX Access Point,
Brocade Mobility 1240 Access Point
• Access Points (as root APs only) — Brocade Mobility 650 Access Point
• Wireless Controllers — Brocade Mobility RFS6000, Brocade Mobility RFS7000
• Service Platforms — Brocade Mobility RFS9510
Syntax:
rate-limit [meshpoint|neighbor]
rate-limit [meshpoint|neighbor] [from-air|to-air] {max-burst-size <2-1024>|
rate <50-1000000>}
rate-limit [meshpoint|neighbor] [from-air|to-air] {red-threshold [background
<0-100>|
best-effort <0-100>|video <0-100>|voice <0-100>]}
Parameters
rate-limit [meshpoint|neighbor] [from-air|to-air] {max-burst-size <2-1024>|
rate <50-1000000>}
meshpoint Configures rate limit parameters for all data received from any meshpoint in the mesh network. This
option is disabled by default.
neighbor Configures rate limit parameters for neighboring meshpoint devices. Enables rate limiting for data
transmitted from the client to its associated access point radio and connected controller. This option is
disabled by default.
from-air Configures rate limits for traffic from the wireless neighbor to the network.
to-air Configures rate limits for traffic from the network to the wireless neighbor.
max-burst-size <2-1024> Optional. Configures the maximum burst size in kilobytes. Set a value from 2 - 1024 kbytes.
For a meshpoint: The smaller the burst, the less likely that the transmit packet transmission results in
congestion for the meshpoint'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.
For a neighbor: The smaller the burst, the less likely the transmit packet transmission will result in
congestion for the wireless client. The default burst size is 64 kbytes.
rate <50-1000000> Optional. Defines a receive or transmit rate limit in kilobytes per second. Set a value from 50 -
1000000 kbps.
For a meshpoint: This limit constitutes a threshold for the maximum the number of packets transmitted
or received over the meshpoint (from all access categories). Traffic that exceeds the defined rate is
dropped and a log message is generated. The default setting is 5000 kbps.
For a neighbor: This limit constitutes a threshold for the maximum the number of packets transmitted
or received (from all access categories). Traffic that exceeds the defined rate is dropped by the client
and a log message is generated. The default rate is 1,000 kbps.
