Description
This command configures a bandwidth contract.
Syntax
Usage Guidelines
You can apply a configured bandwidth contract to a user role or to a VLAN. When you apply a bandwidth
contract to a user role (see “user-role” on page 1241), you specify whether the contract applies to upstream traffic
(from the client to the controller) or downstream traffic (from the controller to the client). You can also specify
whether the contract applies to all users in a specified user role or per-user in a user role.
When you apply a bandwidth contract to a VLAN (see “interface vlan” on page 282), the contract limits
multicast traffic and does not affect other data. This is useful because an AP can only send multicast traffic at the
rate of the slowest associated client. Thus excessive multicast traffic will fill the buffers of the AP, causing frame
loss and poor voice quality. Generally, every system should have a bandwidth contract of 1 Mbps or even 700 Kbps
and it should be applied to all VLANs with which users are associated, especially those VLANs that pass through
the upstream router. The exception are VLANs that are used for high speed multicasts, where the SSID is
configured without low data rates.
Example
The following command creates a bandwidth contract that limits the traffic rate to 1 Mbps:
aaa bandwidth-contract mbits 1
