To configure QoS policy overrides on an L2 or L3 access interface

Purpose

Perform this procedure to override settings associated with an access ingress, access egress, or scheduler policy on an L2 or L3 access interface configured for a service. It is also applicable to multi-service sites.

See the following procedures for information about overriding access ingress, access egress, or scheduler policies that are associated with residential subscribers:

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Expand Access Interface (Service Management) in the object type drop-down menu and choose one of the following:

  • L2 Access Interface (Service Management)

  • L3 Access Interface (Service Management)

3 

Choose an L2 or L3 access interface in the list and click Properties. The L2 | L3 Access Interface (Edit) form opens.

4 

Click on the Override Policy Items tab and perform one of the following:

  1. Create an override for an access ingress tagged IP/IPv6 match entry. Go to Step 5 .

  2. Create an override for an access ingress or access egress policy queue. Go to Step 6 .

  3. Create an override for an access egress policy HSMDA queue. Go to Step 7 .

  4. Create an override for an ingress or egress policy policer. Go to Step 8 .

  5. Create an override for an ingress or egress policer control policy. Go to Step 9 .

  6. Create an override for an ingress or egress scheduler policy. Go to Step 10 .

  7. Create an override for an access egress policy HS WRR group. Go to Step 11 .

5 

To create an override for an access ingress tagged IP/IPv6 match entry, click on the Ingress Criteria tab and configure the required parameters.

6 

To create an override for an access ingress or access egress policy queue, click on the Access Ingress or Access Egress Queues tab.

  1. Click Create.The Access Ingress | Egress Queue Override form opens.

  2. Select an ingress QoS policy queue.

  3. Click on the Override tab.

  4. Select a slope policy on the HS WRED Queue panel, if required.

  5. Configure the required parameters.

    To override parameters, you must select the associated check box. De-select the associated Default or MAX check box to enter a specific value, or to select a drop-down option.

    Overrides for the PIR and CIR are configured in kbps if the Rate Type for the queue was originally set to kbps. The PIR and CIR overrides are configured as a percentage (%) if the Rate Type for the queue was originally set to Percent Port Limit or Percent Local Limit.

    The Port Average Overhead parameter is only configurable for access egress queues.

    For egress queues, you can configure queue depth monitoring in the Stats panel. For more information, see Queue depth monitoring.

  6. Save your changes and close the forms.

7 

To create an override for an access egress policy HSMDA queue, click on the Access Egress HSMDA Queues tab.

  1. Click Create. The Access Egress HSMDA Queue Override form opens.

  2. Select the queue you want to override.

  3. Click on the Override tab.

  4. Configure the required parameters.

    If you select the Override check box for a parameter, the original parameter value is displayed.

    To specific another override value for the PIR (kbps) parameter, you must first deselect the associated MAX check box. To specific another override value for the Maximum Burst Size (bytes) parameter you must first deselect the associated Default check box.

    You can only specify an override value for WRR Weight for queues 1, 2, or 3.

  5. Select the HSMDA Slope policy you want to override.

  6. Save your changes and close the forms.

8 

To create an override for an ingress or egress policy policer, click on the Ingress|Egress Policer tab.

  1. Click Create. The Policer Override form opens.

  2. Click Select and choose a policy policer, then click OK.

    Policy policers must be applied to the L2 Access Interface or the L3 Access Interface in order to be selected.

  4. Click on the Override tab.

  5. Select the Override check box and configure any of the required parameters.

    To override any of the parameters, you must first select the associated check box. Deselect the associated Default or MAX check box to enter a specific value or to select a drop-down parameter option.

    Overrides for the PIR and CIR are configured in kbps if the Rate Type for the policer was originally set to kbps. The PIR and CIR overrides are configured as a percentage if the Rate Type for the policer was originally set to Percent Local Limit.

  6. Save your changes and close the forms.

9 

To create an override for an ingress or egress policer control policy, click on the Schedulers tab.

  1. On the Ingress|Egress Policer Control Override panel, click Create. The Policer Control Override form opens.

    Policer control policies must be applied to the L2 or L3 access interface in order for the policer control override panels to be displayed.

  2. Configure the required override check boxes and parameters.

  3. Click OK to apply the changes and close the Policer Control Override form.

  4. Click Apply in the L2 | L3 Access Interface form.

  5. Select the policer control override you just created and click Properties. The Policer Control Override form opens.

  6. Click on the Level Override Policy Items tab.

  7. Select a level override from the list and click Properties. The Policer Level Override form opens.

  8. Click on the Override tab.

  9. Select the Override check box and configure the Maximum Cumulative Buffer Space parameter.

  10. Save your changes and close the forms.

To create an override for an ingress or egress scheduler policy, click on the Ingress|Egress Schedulers tab. (Ingress or egress scheduler policies must be applied to the L2 or L3 access interface in order for the Ingress or Egress Scheduler tabs to appear under the Override Policy Items tab.)

  1. Click Create. The Policy Scheduler Override form opens.

  2. Select a scheduler policy.

  3. Click on the Override tab.

  4. Select the Override check box and configure any of the required parameters.
