Configuring VC Bundling with IP and ATM QoS
To configure the bandwidth associated with each of the four classes, use the following commands,
beginning in global configuration mode:
Example
The following example configures the bandwidth associated with each of the four classes on a policy
map named arm2-switch1:
Switch1(config)# policy-map arm2-switch1
Switch1(config-pmap)# class voice
Switch1(config-pmap-c)# bandwidth 200000 random-detect buffer-group 3 max-probability 100
freeze-time 15
Switch1(config-pmap-c)# exit
Switch1(config-pmap)# class video
Switch1(config-pmap-c)# bandwidth 175000 random-detect buffer-group 2 max-probability 100
freeze-time 15
Switch1(config-pmap-c)# exit
Switch1(config-pmap)# class HiPri
Switch1(config-pmap-c)# bandwidth 100000 random-detect buffer-group 1 max-probability 100
freeze-time 15
Switch1(config-pmap-c)# exit
Switch1(config-pmap)# class class-default
Switch1(config-pmap-c)# bandwidth 25000 random-detect buffer-group 0 max-probability 100
freeze-time 15
Switch1(config-pmap-c)# end
Switch1#
Command Purpose
Step1 Switch(config)# policy-map policy-map-name
Switch1(config-pmap)#
Specifies the policy map name and changes to policy
map configuration mode.
Step2 Switch(config-pmap) # class class-name Specifies the name of a predefined class, which was
defined with the class-map command.
Step3 Switch(config-pmap-c) # bandwidth kbps Specifies a minimum bandwidth (in Kbits/sec)
guaranteed to a traffic class. This must be sp ecified
for each class in the output policy, including
class-default.
Step4 Switch(config-pmap-c) # random-detect [buffer-group
buffer-group-number | max-probability max-probability |
freeze-time millisecond]
Enables and configures the XPIF based Random
Early Detect (xRED) drop policy.
Step5 Switch(config-pmap-c) # class class-default Specifies the default class.
Step6 Switch(config-pmap-c) # exit
Switch(config-pmap) #
Exits back to policy map configuration mode.
