Quality of Service Commands on the Cisco IOS XR Software

bandwidth (QoS)
To specify the minimum bandwidth allocated to a class belonging to a policy map, use the bandwidth
command in policy map class configuration mode. To remove the bandwidth specified for a class, use the no
form of this command.
bandwidth {rate [units ]| percent percentage-value}
no bandwidth {rate [units ]| percent percentage-value}
Syntax Description Minimum bandwidth, in the units specified, to be assigned to the class. Range
is from 1 to 4294967295.
rate
Specifies the units for the bandwidth. Values can be:
•bps—bits per second
•gbps—gigabits per second
•kbps—kilobits per second (default)
•mbps—megabits per second
units
Specifies the amount of guaranteed bandwidth, based on an absolute percentage
of available bandwidth. Range is from 1 to 100.
percent percentage-value
Command Default The default units is kbps.
Command Modes Policy map class configuration
Command History ModificationRelease
This command was introduced.Release 2.0
The ability to select the units for the bandwidth was added.
The range of bandwidth values was changed from 8 to 4000000 to 1 to
4294967295.
Release 3.3.0
Minimum rate value changed from 128 kbps to 256 kbps.Release 3.3.1
Usage Guidelines You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
