HP MSR2000/3000/4000 Router Series ACL and QoS Command Reference

85
Usage guidelines
The maximum reserved bandwidth is set on a per-interface basis and decides the maximum bandwidth
assignable for the QoS queues on an interface. It is typically set no greater than 80% of available
bandwidth, considering the bandwidth for control traffic and Layer 2 frame headers.
Use the default maximum reserved bandwidth setting in most situations. If you adjust the setting, make
sure the Layer 2 frame header plus the data traffic is under the maximum available bandwidth of the
interface.
The maximum available bandwidth of an interface can be configured by using the bandwidth command.
For more information about this command, see Interface Command Reference.
Examples
# Set the maximum reserved bandwidth to 70% of available bandwidth on interface Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] qos reserved-bandwidth 70
queue af
Use queue af to enable assured-forwarding (AF) and set its minimum guaranteed bandwidth.
Use undo queue af to delete the configuration.
Syntax
queue af bandwidth { bandwidth | pct percentage | remaining-pct remaining-percentage }
undo queue af
Default
AF is not configured.

Parameters
bandwidth: Specifies the bandwidth in the range of 8 to 10000000 kbps.
pct percentage: Specifies the percentage of the available bandwidth. The value range for this argument
is 1 to 100.
remaining-pct remaining-percentage: Specifies the percentage of the remaining bandwidth. The value
range for this argument is 1 to 100.
Usage guidelines
To associate the traffic behavior configured with the queue af command with a class in a policy, you must
follow these requirements:
• The total bandwidth assigned to AF and EF in a policy must be no more than the maximum
available bandwidth of the interface where the policy is applied.
• The total percentage of bandwidth assigned to AF and EF in a policy must be no more than 100.
