. Setting the egress rate

Example

-3: Setting the maximum bandwidth limit for each user

In example

, we configured an egress rate on ports. But the granularity of that bandwidth

limiting was multiples of 640kbps. To achieve a finer-grained limiting on egress, it is necessary

to make use of traffic classes. In this example we assume that there is one device with a

known IP address, attached to each port. A traffic class will be created for each such IP

address, and a maximum bandwidth applied to the traffic class.

This set of commands will set the total egress limit (download traffic) for each user to

256kbps. The granularity is around

kbps.
