Configuring the maximum available interface bandwidth

The maximum available interface bandwidth refers to the maximum interface bandwidth used for

bandwidth check when CBQ enqueues packets, rather than the actual bandwidth of the physical

interface.

Configuration guidelines

• HP recommends that you configure the maximum available interface bandwidth to be smaller than

the actual available bandwidth of the physical interface or logical link.

• On a primary channel or template interface (such as VT) configured with the qos max-bandwidth

command, AF and EF queues perform queue bandwidth check and calculation based on the

bandwidth specified with the qos max-bandwidth command, so do the AF and EF queues

synchronized to the sub-channel interfaces (for example, VA interfaces or B channels). Sub-channel

interface bandwidth is ignored. Because the QoS configurations of the primary channel interface

and the sub-channel interfaces are the same, prompts are output only for the primary channel

interface. If the qos max-bandwidth command is not configured, AF and EF queues on the primary

channel interface calculate queue bandwidth based on 1 Gbps of bandwidth, and AF and EF

queues synchronized to the sub-channel interfaces calculate queue bandwidth based on actual

sub-channel interface bandwidth. If queuing on a sub-channel interface fails due to bandwidth

change, the prompt will be output for the sub-channel interface.

• On an MP-group interface or MFR interface configured with the qos max-bandwidth command, AF

and EF perform queue bandwidth check and calculation based on the bandwidth specified with the

qos max-bandwidth command. On an MP-group interface or MFR interface without the qos

max-bandwidth command configured, if the sum of sub-channel bandwidth equals to or exceeds

the sum of AF bandwidth and EF bandwidth, AF and EF calculate bandwidth based on the actual

interface bandwidth. Otherwise, AF and EF calculate bandwidth based on 1 Gbps of bandwidth,

and the message indicating insufficient bandwidth is displayed. In the latter case, the queuing

function might fail to take effect.

• On tunnel interfaces, subinterfaces, Layer 3 aggregate interfaces, HDLC link bundle interfaces, RPR

logical interfaces, or VT interfaces using PPPoE, PPPoA, or PPPoEoA at the data link layer, you must

configure the qos max-bandwidth command to provide base bandwidth for CBQ calculation.
