Cbwfq Example Configuration - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

N o t e
Even when you assign bandwidth to classes as a percentage, the router assigns
it as an absolute value of the bandwidth normally available on the interface.
This means that when one or more lines in a multilink bundle goes down, the
router does not automatically readjust the bandwidth allocated to various
classes.

CBWFQ Example Configuration

In Figure 7-5, Site A includes two networks that connect to the Internet. It also
connects to remote Site B through a virtual private network (VPN). Your
organization does not want Internet traffic to starve out traffic to the remote
site. You can configure CBWFQ to reserve at least 25 percent of the bandwidth
for Network 1 to access the remote site and 20 percent for Network 2. Site A
also includes the company Web server. Company policy dictates that 15
percent of the bandwidth must be reserved for traffic from the server.

You would implement this policy as follows:
