Item Description
Radio List
List of radios available. You can create the rate limiting rules for one or multiple
radios.
Direction
Traffic direction:
• Inbound—Traffic from clients to the AP.
• Outbound—Traffic from the AP to clients.
• Both—Includes inbound traffic (traffic from clients to the AP) and outbound traffic
(traffic from the AP to clients)
Mode
Rate limiting mode:
• Static—Limits the rate of each client to a fixed value.
• Dynamic—Limits the total rate of all clients to a fixed value.
Rate
Set the rate of the clients:
• If you select the static mode, Per-Client Rate is displayed, and the rate is the rate
of each client.
• If you select the dynamic mode, Total Rate is displayed, and the rate is the total
rate of all clients.
Configuring the bandwidth guarantee function
When traffic is heavy, a BSS without any rate limitation may aggressively occupy the available
bandwidth for other BSSs. If you limit the rate of the BSS, it cannot use the idle bandwidth of other BSSs.
To improve bandwidth use efficiency when ensuring bandwidth use fairness among wireless services, use
the bandwidth guarantee function. Bandwidth guarantee makes sure all traffic from each BSS can pass
through freely when the network is not congested, and each BSS can get the guaranteed bandwidth
when the network is congested.
For example, suppose you guarantee SSID1, SSID2, and SSID3 25%, 25%, and 50% of the bandwidth.
When the network is not congested, SSID1 can use all idle bandwidth in addition to its guaranteed
bandwidth. When the network is congested, SSID1 can use at least its guaranteed bandwidth, 25% of
the bandwidth.
NOTE:
Bandwidth guarantees apply only to the traffic from AP to client.
Setting the reference radio bandwidth
1. Select QoS > Wireless QoS from the navigation tree.
2. Click the Bandwidth Guarantee tab to enter the page for configuring bandwidth guarantees, as
shown in
Figure 575 .
