Select one or more interfaces by taking one of the following actions:
•
To configure a single interface, select the check box associated with the port, or
type the port number in the Go To Interface field and click the Go button.
•
To configure multiple interfaces with the same settings, select the check box
associated with each interface.

8. From the Queue ID menu, select the queue.
You can select a queue from 0 to 7.
9.
In the Minimum Bandwidth field, specify the minimum guaranteed bandwidth
allotted to the queue on the interface.
Setting this value higher than its corresponding maximum bandwidth automatically
increases the maximum to the same value. The default value is 0. The range is from
0 to 100 in increments of 1. The value 0 means that no guaranteed minimum
bandwidth is applied. The sum of the individual minimum bandwidth values for all
queues on the selected interface cannot exceed the maximum (100).
The setting applies only to the queue that you select from the Queue ID menu.
10.
From the Scheduler Type menu, select the type of scheduling that is used for the
queue on the interface:
•
Strict: The interface services traffic with the highest priority on a queue first.
•
Weighted: The interface uses weighted round robin to associate a weight to each
queue. This is the default setting.
The setting applies only to the queue that you select from the Queue ID menu.
11. From the Queue Management Type menu, select the queue depth management
method that is used for the queue on the interface:
•
TailDrop: The Taildrop method causes packets to be dropped if the queue is full.
When space becomes available in the queue, packets are once again accepted.
This is the default method.
• WRED: The Weighted Random Early Detection (WRED) method allows you to
refine queue management so that packets are dropped selectively (see Configure
the CoS WRED precedence settings for dropping packets on page 462).
The setting applies only to the queue that you select from the Queue ID menu.
