3Com Router Command Reference Guide Addendum for V1.2

Description

Using qos policy command, you can define a policy and enter map view. Using undo qos policy command, you can delete a policy.

The policy cannot be deleted if it is applied on an interface. It is necessary to remove application of the policy on the current interface before deleting it via the undo qos policy command.

For the related commands, see qos class, qos apply policy.

Example

Define a policy named 3COM.

[3Com] qos policy 3Com

[3Com-qospolicy-3Com]

1.25 qos reserved-bandwidth

Syntax

qos reserved-bandwidth pct percent

undo qos reserved-bandwidth

View

Interface view

Parameter

pct percent: Percentage of reserved bandwidth in available bandwidth, ranging from 1 to 100. By default, it is 75.

Description

Using qos reserved-bandwidthcommand, you can set the percentage of the maximum reserved bandwidth in available bandwidth. Using undo qos reserved-bandwidthcommand, you can recover the default configuration.

While allocating bandwidth for a QoS queue, considering that part of the bandwidth is used for controlling protocol packets and L2 header, it is suggested that the bandwidth be not larger than 75% of total bandwidth.

For the related command, see qos max-bandwidth.
