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 1438 ), 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 330 ), 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
