Sample QoS configuration on the 7450 ESS, 7705 SAR, 7750 SR, and 7950 XRS

Stages
Planning and configuration
 
1 

Perform network planning activities:

  1. Determine the required types of services or applications; for example, voice, video, and data.

  2. Review SLAs.

  3. Perform traffic engineering activities at the IP/MPLS core level to ensure that resources are available.

2 

Configure the IP and MAC ACL filters, as required. See To configure an ACL IP filter policy and  To configure an ACL MAC filter policy for more information.

3 

Configure the slope policies. See To configure a WRED slope policy and To configure an HSMDA WRED slope policy for more information.

4 

Configure the scheduler policies. Scheduler policies can be shared between ingress and egress policies, depending on your specific requirements. See To configure a scheduler policy for more information.

5 

Configure the port scheduler policies. See To configure a port scheduler policy for more information.

6 

As required, create the aggregation schedulers. See To create an Aggregation Scheduler for more information.

7 

Configure the SAP access ingress policies. See To configure a SAP access ingress policy for more information.

  1. Configure the forwarding classes.

  2. Configure the queues.

  3. Map QoS markings on ingress packets to the forwarding classes.

  4. Map forwarding classes to the queue definitions.

  5. Map queue definitions to the scheduler policies.

8 

Configure the SAP access egress policies. See To configure a SAP access egress policy for more information.

  1. Configure the queues.

  2. Map forwarding classes to the queue definitions.

  3. Map queue definitions to the schedulers policies.

9 

Configure the network policies. See To configure a QoS network policy for more information.

  1. Configure for ingress:

    • Map QoS markings on ingress packets to the forwarding classes.

    • Map forwarding classes to the queue definitions.

  2. Configure for egress:

    • As required, configure remarking.

    • As required, map QoS markings to the forwarding classes.

10 

Configure the network queue policies. See To configure a network queue policy for more information.

11 

Configure the time of day policies.

  1. Configure the time ranges. See To configure a time range policy for more information.

  2. Create time of day suites. See To configure a time-of-day suite policy for more information.

Application of policies and schedulers to equipment and interfaces
 
12 

Associate the slope policies with ports or daughter cards. See To configure Ethernet ports and  To configure an MDA for more information.

13 

Associate the network queue policies with MDAs. See To configure Ethernet ports and  To configure an L3 interface on a DS3/E3 channel on a channelized ASAP MDA for more information.

Configuration of customers and services
 
14 

Configure the customers. See the appropriate service chapter for more information.

15 

Create the customer services, and assign policies during the configuration. See the appropriate service chapter for more information.

16 

Assign the aggregation schedulers at the interface level, if required. See the appropriate service chapter for more information.
