Configuring a QoS Profile
Before you configure a QoS profile:
See Configuring Traffic Classes That Define Service Levels.
See Configuring Queue Profiles to Manage Buffers and Thresholds.
See Configuring a Scheduler Hierarchy.
- Create a QoS profile and enter QoS Profile Configuration mode.
- (Optional) Configure a group node for each interface.
host1(config)#qos-profile qosp-vc-queuing
host1(config-qos-profile)#
host1(config-qos-profile)#atm group groupA scheduler-profile scheduler1
statistics-profile statpro-1
When you configure a group node, you can also reference a default or named traffic-class group, a scheduler profile, or a statistics profile.
If you do not specify a traffic-class group, the group node defaults to the default group. Each traffic class can belong to only one traffic-class group (either the default group or a named group).
The router supports up to four traffic-class groups above a given port.
- (Optional) Configure a scheduler node for interfaces.
host1(config-qos-profile)#atm node scheduler-profile scheduler1 group
strict-priority
When you configure a scheduler node, you can also reference a default or named traffic-class group and a scheduler profile.
The scheduler profile supplies a relative weight and potentially a shaping rate to be applied at the scheduler node.
 |
NOTE: You cannot associate a scheduler profile with a port-type interface unless you also specify the strict-priority group. |
- (Optional) Configure a queue for interfaces in the specified traffic class.
host1(config-qos-profile)#atm queue traffic-class strict-priority scheduler-profile
scheduler1 queue-profile queue1 drop-profile drop1
When you configure a queue, you can include any of the following profiles:
- The scheduler profile supplies a relative weight and potentially a shaping rate to be applied at the queue.
- The queue profile supplies threshold information for the queue if the router defaults are not appropriate.
- The drop profile supplies dropping behavior of a set of egress queues.
Each queue traffic class can appear in only one traffic-class group.
