Chapter 5 Distributing Bandwidth Between Queues
Bandwidth Distribution Between Queues
Configuring Bandwidth Distribution Between Queues
To configure or modify the amount of bandwidth allocated for a traffic class, enter the following
commands beginning in global configuration mode:
For information about classifying traffic and creating QoS service policies, see Chapter 2, “Classifying
Traffic” and Chapter 3, “Configuring QoS Policy Actions and Rules.”
Configuration Examples for Configuring Bandwidth Distribution
This section provides the following configuration examples:
• Configuration Example for Kilobits per Second-Based Bandwidth, page 5-11
• Configuration Example for Percentage-Based Bandwidth, page 5-11
• Configuration Example for Bandwidth-Remaining-Based Bandwidth, page 5-11
Command Purpose
Step 1
Router(config)# policy-map policy-map-name
Specifies the name of the policy map and enters policy-map
configuration mode.
policy-map-name is the name of the policy map.
Step 2
Router(config-pmap)# class class-map-name
Assigns the traffic class you specify to the policy map. Enters
policy-map class configuration mode.
class-map-name is the name of a previously configured class
map and is the traffic class for which you want to define QoS
actions.
Step 3
Router(config-pmap-c)# bandwidth
{bandwidth-kbps | percent percentage |
remaining percent percentage}
Specifies or modifies the minimum bandwidth allocated for a
traffic class in a policy map.
bandwidth-kbps specifies or modifies the minimum
bandwidth allocated for a class belonging to a policy map.
Valid values are from 8 to 2,488,320, which represents from
1
to 99 percent of the link bandwidth.
Note The range of valid values for bandwidth-kbps might
be smaller than the values indicated above. Use the
question mark (?) in context-sensitive help to display
the range of valid values.
percent percentage specifies or modifies the minimum
percentage of the link bandwidth allocated for a class
belonging to a policy map. Valid values are from 1 to 99.
remaining percent percentage specifies or modifies the
minimum percentage of unused link bandwidth allocated for
a class belonging to a policy map. Valid values are from 1 to
99.
Note Configure the amount of bandwidth large enough to
also accommodate Layer 2 overhead.
