To configure a SAP access egress policy

Steps
 

Choose Policies→QoS→SROS QoS→Access Egress→SAP Access Egress from the NFM-P main menu. The SAP Access Egress Policies form opens.


Click Create, or choose a policy in the list and click Properties. The SAP Access Egress Policy (Create|Edit) form opens.


Configure the required general parameters.

Note: For some of the following steps, the tabs are not available until after the policy is created. Click Apply if required to create the policy and make all tabs available.

Note: NEs that support next-generation CLI use the policy name as the key identifier for internal system reference. For policies on these NEs, you must configure a policy name (typically the service name or a numerical string). Policy IDs are also supported. You must configure a numerical range on the NE for auto-assigned policy IDs; see To configure an Auto-ID range for policies.


Enable the Policers HQoS Manageable parameter if the policers in this policy are to be managed by the Hierarchical QoS process.


If the SAP access egress policy requires the forwarding class to be changed to an alternate queue than the ingress forwarding class determination would have used, or you need to modify the forwarding profile to modify the congestion behavior of the egress queue, select a policy in the Post Policer Mapping Policy panel.


Click Select in the HS panel to associate an alternate HS Attachment Policy other than the default policy. The Select HS Attachment Policy – Egress Queue Group Template Policy form opens.


Select the required HS Attachment Policy and click OK.


If you are creating a 7705 SAR MC MLPPP access egress policy, configure the Use As Multiclass MLPPP Policy For 7705 SAR parameter and select a WRR Policy in the Egress HSMDA panel.


Configure HSMDA queues.

  1. Click on the HSMDA Queues tab. Eight default queues are displayed.

  2. Choose a queue and click Properties. The Access Egress HSMDA Queue (Create) form opens.

  3. Configure the required general parameters.

  4. Select a slope policy in the Slope Policy panel.

  5. Click on the PIR/Burst Size tab and configure the required parameters.

    To configure the parameters, deselect the MAX or Default check boxes as required.

  6. Save your changes and close the forms.

Configure access egress queues.

  1. Click on the Queues tab.

    The NFM-P provides a default egress queue (ID 1). You can modify the default queue but you cannot delete queue ID 1.

  2. Click Create, or choose a queue and click Properties. The Queue (Create|Edit) form opens.

    You can create up to eight queues.

  3. Configure the required general parameters.

    Note:

    You must enable the Use WRED Queue parameter to display and configure additional parameters associated with a WRED queue.

  4. Select a Slope Policy, Pool Name, Advanced Configuration Policy, and Scheduler.

    Before you can select a Pool Name, you must create a Q1 pool; see To configure Q1 pools .

    Scheduler selection is available when the Port Parent parameter is set to false.

    The hardware aggregate shaper scheduler policy can be supported using Shaper Weight and Scheduler Class parameters. See To configure a Hardware Aggregate Shaper Scheduler policy.

  5. Click on the CIR/PIR tab and configure the required parameters.

    You can configure the CIR and PIR as a rate or as a percentage, depending on the option selected for the Rate Type parameter.

  6. Click on the Burst Size tab and configure the required parameters.

    Deselect the Default check box for each parameter that you need to configure.

    Ensure that the Committed Burst Size (KB) value is lower than the Maximum Burst Size (bytes) value.

  7. Click on the HSQ tab if required and configure the required parameters. You can only configure HSQ on default queue entries 1 to 8.

  8. Select a HS WRED Slope Policy if required and click OK.

    Note: To configure the parameters on the HS WRED Slope Policy Properties form, you must first create a HS WRED Slope policy. See To configure a WRED slope policy.

  9. Save your changes and close the form.


11 

Configure a dynamic policer.

  1. Click on the Dynamic Policer tab and configure the required general parameters.

  2. Select a Parent Arbiter.

  3. Click on the Burst Size tab and configure the Committed Burst Size and Maximum Burst Size parameters.

    Deselect the Default check box for each parameter that you need to configure.

    Ensure that the Committed Burst Size value is lower than the Maximum Burst Size value.


12 

Configure egress policers.

  1. Click on the Policer tab.

  2. Click Create, or choose a policer and click Properties. The Access Egress Policer (Create|Edit) form opens.

  3. Configure the general parameters.

  4. Select a Parent Arbiter and an Advanced Configuration Policy.

  5. Select a Scheduler Parent if required, and then configure the parameters in the Scheduler Association panel.

    Note:

    You cannot configure a Scheduler Parent and a Port Parent. They are mutually exclusive.

  6. Set the Port Parent parameter to True if you need to create a port parent association for the policer, as opposed to a scheduler association. You can then configure the parameters in the Port Parent Association panel.

  7. Click on the CIR/PIR tab and configure the required parameters.

    You can configure the CIR and PIR as a rate or as a percentage, depending on the option selected for the Rate Type parameter.

  8. Click on the Burst Size tab and configure the required parameters.

    Deselect the Default check box for each parameter that you need to configure.

  9. Save your changes and close the form.


13 

Configure forwarding classes. You can create up to eight forwarding classes.

  1. Click on the Forwarding Classes tab.

  2. Click Create, or choose a forwarding class and click Properties. The Forwarding Class (Create|Edit) form opens.

  3. Configure the Forwarding Class parameter.

  4. Complete one of the following for each Forwarding Class you configure:
    • If you need to configure a policer, set the Traffic Control parameter for the Use Policer option and go to 5 .

    • If you need to configure a local queue, set the Traffic Control parameter for the Use Queue option and configure the Port Redirect Queue Group parameter as required, then go to 9 .

    • If you need to configure a queue from a queue group, set the Traffic Control parameter to the Use Queue Group option and go to 7 .

  5. In the Policers panel, select a policer.

  6. Configure the Port Redirect Queue Group parameter as required. If you disable this parameter, then go to 7 . Otherwise go to 9 .

  7. In the Queue Group panel, select a Queue Group Template Policy.

  8. Configure the Instance ID parameter.

  9. In the Queue panel, select a queue.

    Note:

    You cannot map a Forwarding Class to a non-existent or deleted Queue ID. Use the Select button to choose a Queue ID, as opposed to manually entering it in the Queue ID field.

    The queue you can select here is dependent on the Traffic Control parameter setting you chose in 4 , as follows:
    • Use Queue: If you specified this setting, then you can only select a locally-defined queue. The local queue in this context is either the default queue or one you created for this policy in Step 10 . The local queue you select here must be set to a unicast ID. The default ID for unicast queues is 1. Alternatively, you can manually enter 0 if you want the default Queue ID to be used.

    • Use Queue Group: If you specified this setting, then you can only select one of the queues defined in the Queue Group Template Policy you chose in 7 .

      Note:

      If the Use Queue Group option is enabled for the global policy, then the Queue ID you select is validated against the specified Queue Group Template Policy. The Queue ID is validated against the local queues for each local policy instance.

      You cannot delete a Queue Group Template Policy that is referenced by a queue group.

    • Use Policer: If you specified this setting and disabled the Port Redirect Queue Group parameter in 6 , then you can select one of the queues defined in the Queue Group Template Policy you chose in 7 . If you enabled the Port Redirect Queue Group parameter in 6 , then select the required local queue here.

  10. In the Hsmda Queue panel, configure the Queue ID and Port Redirect Queue Group parameters, as required.

  11. Configure the required parameters in the Dot1p and Properties panels.

  12. Save your changes and close the form.
