Cbq Configuration Example - HP FlexNetwork MSR Series Configuration Manuals

Use the default maximum reserved bandwidth setting in most situations. When tuning the setting,
make sure the Layer 2 frame header plus the data traffic is smaller than the maximum available
bandwidth of the interface.
To set the maximum reserved bandwidth on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Set the maximum reserved
bandwidth as a percentage
of available bandwidth.

CBQ configuration example

Network requirements
As shown in
•
Traffic from Router C is classified into three classes based on DSCP values. Perform AF for
traffic with DSCP values of AF11 and AF21, and set a minimum guaranteed bandwidth
percentage of 5% for the traffic.
•
Perform EF for traffic with a DSCP value of EF and set the maximum bandwidth percentage for
the traffic to 30%.
Before configuring the QoS policy, make sure the following requirements are met:
•
The route from Router C to Router D through Router A and Router B is reachable.
•
The DSCP fields have been set for the traffic before the traffic enters Router A.
