• You cannot configure the queue ef command together with the any of the commands queue af and
queue-length for a traffic behavior.
• The default class cannot be associated with a traffic behavior including EF.
• To configure queue ef for multiple classes of a policy, you must configure them in one of the
following units:
{ Bandwidth.
{ Percentage of the available bandwidth.
• To configure both the queue ef command and the queue af command in a policy, you must
configure them in the same unit (either bandwidth or percentage). When you configure AF in
percentage of the remaining bandwidth, you can configure EF in an absolute value or percentage.
To configure EF and the maximum bandwidth:

Command Remarks
1. Enter system view.

2. Create a traffic behavior and
enter traffic behavior view.
traffic behavior behavior-name By default, no behavior is created.
3. Configure EF and the
maximum bandwidth.
queue ef bandwidth { bandwidth
[ cbs burst ] | pct percentage
[ cbs-ratio ratio] }
By default, EF is not configured.
Configuring WFQ

traffic behavior behavior-name By default, no behavior is created.
3. Configure WFQ.
queue wfq [ queue-number
total-queue-number ]
By default, WFQ is not configured.
You can associate the traffic behavior that contains a WFQ action only with the default class.
Configuring the maximum queue size

Command Remarks
1. Enter system view.
system-view N/A
2. Create a traffic behavior and
enter traffic behavior view.
traffic behavior behavior-name By default, no behavior is created.
3. Set the maximum queue size.
queue-length queue-length
By default, tail drop is used and the
queue size is 64.
If the burst traffic is too heavy,
increase the queue length to make
queue scheduling more accurate.
Configure the queue af command or the queue wfq command before you configure the queue-length
command. The undo queue af or undo queue wfq command also cancels the queue-length command.
