1826 CHAPTER 115: CBQ C ONFIGURATION COMMANDSParameters bandwidth: Maximum bandwidth available on an interface, in the range 1 to1000000 kbpsDescription Use the queue max-bandwidth command to configure the maximumbandwidth available on an interface.Use the undo queue max-bandwidth command to restore the default.By default:For a physical interface, the value is the actual baudrate or speed of the physicalinterface;For logical serial interfaces such as T1/E1 and MFR created by binding the value isthe 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 theactual available bandwidth of physical interface or logical link.■ Modification of the maximum available bandwidth may trigger CBQreconstruction, thus resulting in CBQ’s reallocation of queue width. Themodification of the baudrate or speed of a physical interface, however, doesnot trigger this reconstruction process.■ To apply QoS policies to a logical interface properly, you must use theshutdown command to shut down all the physical interfaces bound to thelogical interface and then use the undo shutdown command to bring upthese physical interfaces again.Examples # Configure the maximum bandwidth on the interface Ethernet1/0 to 16 kbps. system-view[Sysname] interface ethernet1/0[Sysname-Ethernet1/0] qos wfq queue-length 100queue afSyntax queue af bandwidth { bandwidth | pct percentage }undo queue afView Traffic behavior viewParameters 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 theminimum bandwidth used.Use the undo queue af command to cancel the configuration.
