aaa bandwidth-contract
aaa bandwidth-contract <name> {kbits <kbits>|mbits <mbits>}
Description
This command configures a bandwidth contract.
Syntax
Parameter Description Range
<name>
Name that identifies this bandwidth contract. —
kbits <bits>
Limit the traffic rate for this bandwidth contract to a
specified number of kilobits per second.
256-2000000
mbits <bits>
Limit the traffic rate for this bandwidth contract to a
specified number of megabits per second.
1-2000
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 2201), 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 475), 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 commands configure a set of bandwidth contracts, then apply those contracts to all upstream
and downstream traffic except for the echo, icmp, iperf, icmp6, and synflood applications, and the web,
streaming, peer-to-peer, unified-communication, and tunneling application categories.
