aaa bandwidth-contract

aaa bandwidth-contract {kbits }|{mbits }|{percentage }

Description

This command configures a bandwidth contract. 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 (seeuser-role on page 1), you specify whether the contract applies to upstream traffic (from the client to themanaged device) or downstream traffic (from themanaged deviceto 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 (seeinterface vlan on page 1), 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.
