When associating the class with the queue af behavior in the policy, the following
must be satisfied.
The sum of the bandwidth specified for the classes in the same policy to assured
forwarding (queue af) and expedited forwarding (queue ef) must be less than or
equal to the available bandwidth of the interface where the policy is applied.
The sum of percentages of the bandwidth specified for the classes in the same
policy to assured forwarding (queue af) and expedited forwarding (queue ef)
must be less than or equal to 100.
The bandwidth configuration for the classes in the same policy to assured
forwarding (queue af) and expedited forwarding (queue ef) must adopt the
value of the same type. For example, they all adopt the absolute value form or the
percentage form.
Related commands: qos policy, traffic behavior, classifier behavior.
Examples # Configure traffic behavior named database and configure the minimum
bandwidth of the traffic behavior to 200 kbps.
<Sysname> system-view
[Sysname] traffic behavior database
[Sysname-behavior-database] queue af bandwidth 200
queue ef
Syntax queue ef bandwidth { bandwidth [ cbs burst ] | pct percentage [ cbs-ratio ratio ]}
undo queue ef
View Traffic behavior view
Parameters bandwidth: Bandwidth in kbps, in the range 8 to 1000000.
cbs burst: Specifies the committed burst size in byte, in the range 32 to 2000000,
By default, burst is bandwidth*25.
pct percentage: Percentage of available bandwidth, in the range 1 to 100.
cbs-ratio ratio: Committed burst percentage, in the range 25 to 500. By default,
the value is 25.
Description Use the
queue ef command to configure EF packets to the absolute priority
queue and configure the maximum bandwidth.
Use the
undo queue ef command to cancel the configuration.
When configuring this command, keep the following in mind:
The command can not be used together with queue af, queue-length, and
wred in traffic behavior view.
