bandwidth
bandwidth
To configure class-based weighted fair queuing (CBWFQ) by setting the output bandwidth for a
policy-map class, use the bandwidth command in policy-map class configuration mode. To remove the
bandwidth setting for the class, use the no form of this command.
bandwidth {rate | percent value | remaining percent value}
no bandwidth [rate | percent value | remaining percent value]
Syntax Description
Defaults No bandwidth is defined.
Command Modes Policy-map class configuration
Command History
Usage Guidelines You use the bandwidth policy-map class command to control output traffic. The bandwidth command
specifies the bandwidth for traffic in that class. CBWFQ derives the weight for packets belonging to the
class from the bandwidth allocated to the class and uses the weight to ensure that the queue for that class
is serviced fairly. Bandwidth settings are not supported in input policy maps.
• Configuring bandwidth for a class of traffic as an absolute rate (kilobits per second) or a percentage
of total bandwidth represents the minimum bandwidth guarantee (CIR) for that traffic class.
• You cannot configure bandwidth as an absolute rate or a percentage of total bandwidth when
priority is configured for another class in the output policy. However, you can configure CIR, PIR,
and EIR bandwidth independently for a class so can use the bandwidth, bandwidth remaining, and
shape average commands at the same time within a class.
rate Sets the bandwidth rate for the class in kilobits per second (kbps).
The range is from 1 to 10000000 Kb/s
Note The total guaranteed bandwidth cannot exceed the total
available rate or total bandwidth of the interface.
percent value Sets the bandwidth for the class as a percent of the parent policy
peak information rate (PIR) or shape value. The range is from 1 to
100 percent.
Note The total guaranteed bandwidth cannot exceed the total
available rate or total bandwidth of the interface.
remaining percent value Sets the bandwidth for the class as a percent of the remaining
bandwidth. The range is from 0 to 100 percent.
Note he total guaranteed bandwidth cannot exceed the total
available rate or total bandwidth of the interface.
