1826 CHAPTER 115: CBQ CONFIGURATION COMMANDS

Parameters	bandwidth: Maximum bandwidth available on an interface, in the range 1 t
	o1000000 kbps
Description	Use the queue max-bandwidthcommand to configure the maximum
	bandwidth available on an interface.
	Use the undo queue max-bandwidthcommand to restore the default.
	By default:
	For a physical interface, the value is the actual baudrate or speed of the physical
	interface;
	For logical serial interfaces such as T1/E1 and MFR created by binding the value is
	the sum of bandwidth on the channels they are bound to.
	For logical interfaces such as Virtual Template and VE, the value is 0 kbps.
n	■ It is recommended that the maximum available bandwidth be smaller than the
	actual available bandwidth of physical interface or logical link.
	■ Modification of the maximum available bandwidth may trigger CBQ
	reconstruction, thus resulting in CBQ’s reallocation of queue width. The
	modification of the baudrate or speed of a physical interface, however, does
	not trigger this reconstruction process.
	■ To apply QoS policies to a logical interface properly, you must use the
	shutdown command to shut down all the physical interfaces bound to the
	logical interface and then use the undo shutdown command to bring up
	these physical interfaces again.
Examples	# Configure the maximum bandwidth on the interface Ethernet1/0 to 16 kbps.
	<Sysname> system-view
	[Sysname] interface ethernet1/0
	[Sysname-Ethernet1/0] qos wfq queue-length 100

queue af

Syntax queue af bandwidth { bandwidth pct percentage }

undo queue af

View Traffic behavior view

Parameters bandwidth: Bandwidth in kbps, in the range 8 to 1000000.

percentage: Percentage of the available bandwidth, in the range 1 to 100.

Description Use the queue af command to configure the class to perform AF and the minimum bandwidth used.

Use the undo queue af command to cancel the configuration.
