Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers
Examples
Following are additional examples of configuring MDRR:

•
Configuring Per-VC MDRR and Low Latency Queueing with Queue Limits
In the following example, per-VC MDRR and LLQ are configured with nondefault queue limits.
Configure the policy map as shown in the example:
Router(config)# policy-map MDRRandQlimit
Router(config-pmap)# class class1
Router(config-pmap-c)# priority
Router(config-pmap-c)# class class2
Router(config-pmap-c)# bandwidth remaining percent 50
Router(config-pmap-c)# queue-limit 576 cells
Router(config-pmap-c)# class class-default
Router(config-pmap-c)# queue-limit 576 cells
After the policy map has been created, configure it on the VC using the service-policy command.
Configuring Per-VC MDRR and Policed Low Latency Queueing
If the police command is used with the exceed-action set to drop on the priority queue, then the
bandwidth command can be used with either a percent or kbps specified.
The following example uses the bandwidth percent command to guarantee bandwidth to nonpriority
classes. Twenty percent of the VC rate is guaranteed to class2.
Router(config)# policy-map MDRR-POLICE-LLQ
Router(config-pmap)# class class1
Router(config-pmap-c)# priority
Router(config-pmap-c)# police 64000000 conform-action transmit exceed drop
Router(config-pmap-c)# class class2
Router(config-pmap-c)# bandwidth percent 20
Router(config-pmap-c)# end
Router#
The next example uses the bandwidth remaining percent command, and specifies that 20 percent of
the remaining bandwidth is guaranteed to class2.
Router(config)# policy-map MDRR-POLICE-LLQ
Router(config-pmap)# class class1
Router(config-pmap-c)# priority
Router(config-pmap-c)# police 64000000 conform-action transmit exceed drop
Router(config-pmap-c)# class class2
Router(config-pmap-c)# bandwidth remaining percent 20
Router(config-pmap-c)# end
Router#
After the policy map has been created, configure it on the VC using the service-policy command.
Configuring the set Commands
This task illustrates how to configure the toggling of various bits, such as the ATM CLP, the IP DSCP,
the IP precedence, and the MPLS experimental. Setting of the ATM CLP bit is only supported on egress
queues; setting of all other bits is supported on both ingress and egress queues.
