3Com MSR 50, MSR 30 manual Queue ef, 1827

1827

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-ratioratio: 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.
