Using  qos max-bandwidth command, you can set the maximum bandwidth of an 

interface. Using undo qos max-bandwidth command, you can remove the setting of 

the maximum bandwidth. 

By default,

 the maximum bandwidth is not configured for all interfaces. 

The bandwidth set by this command is only a logic value, not the actual bandwidth of 

an interface. It is suggested that this value not be configured on a common physical 

interface, as it is only used for CBQ bandwidth calculation. The actual bandwidths of 

some interfaces, such as virtual template interface, physical interface configured with 

Line-Rate and DTE interface used for bandwidth negotiation, are unavailable. 

Therefore this command is usually configured on these interface. 

Note: When the actual available bandwidth (the maximum bandwidth multiplied by the 

percentage of reserved bandwidth) of an interface is smaller than the sum of the 

bandwidths (including class-related bandwidths of CBQ and the sum of RTP 

bandwidths) configured by the user, the configuration of enabling CBQ or RTP on the 

interface will be automatically canceled due to lack of bandwidth. If the configured 

bandwidth only fits into one of above requirements, the CBQ configuration will be 

reserved preferentially. 

For the related command, see qos reserved-bandwidth. 

Set the bandwidth of Virtual-Template 1 to 128kbit/s.
