To configure a 7210, 7250, and 1830 SAP Access Ingress policy

Purpose

A 7210, 7250 and 1830 SAP Access Ingress policy defines forwarding for traffic entering from a service. The policy specifies the following:

  • an FC and profile for packets, based on MAC and IP match criteria, or dot1p or DSCP classification

  • a default FC and profile for packets that do not meet any of the match criteria

  • mapping of FCs to ingress meters or queues

  • ingress meters, with rate values (CIR, PIR), burst sizes, and algorithm modes

  • ingress queues, with rate values (CIR, PIR), scheduler priority values, and assigned queue management or slope policies

Meters are defined for unicast and multipoint traffic, and are mapped to FCs according to the user-defined configuration in the policy. The maximum number of meters supported on a local policy varies depending on the chassis type.

The 7210 SAS-K and 7210 SAS-X support ingress queues. The 7210, 7250 and 1830 SAP Access Ingress policy allows the creation of up to eight queues per SAP, and maps the queues to FCs according to the user-defined configuration in the policy. For the 7210 SAS-K, unicast and multicast ingress queues are configured in the policy. For the 7210 SAS-X, ingress multipoint traffic is handled separately; see To configure a 7210 multipoint bandwidth management policy .

The 7210, 7250 and 1830 SAP Access Ingress policy is assigned to L2 access interfaces on VPLS and VLL services, and to L3 access interfaces on IES and VPRN services. See the following procedures, according to the service type:

The NFM-P provides one default 7210, 7250 and 1830 SAP Access Ingress policy (policy ID 1). The default policy cannot be deleted or modified, and is assigned to an interface unless a user-defined policy is explicitly assigned. The default policy defines two default meters, one for unicast traffic (Meter 1) and one for multipoint traffic (Meter 11). The default meters map all packets to the be (best effort) FC.

MAC and IP match criteria entries consume NE system resources. The system resource profile for a 7210 SAS NE that uses the policy must be configured appropriately. See  System resource profile in Chapter 6, Device support for more information.

You can override the settings for meters and queues in access ingress policies that are assigned to access interfaces. For information about policy overrides for access ingress meters on 7210 SAS NEs, see To configure QoS policy overrides on access ingress meters for the 7210 SAS . For information about policy overrides for access ingress queues on 7210 SAS-X NEs, see To configure QoS policy overrides on access ingress queues for a 7210 SAS-X .

The 7210, 7250 and 1830 SAP Access Ingress policy is supported on all 7210 SAS chassis types. If you are configuring a SAP access ingress policy for a 7250 IXR, see To configure a SAP access ingress policy. For more information about QoS policy support on the 7250 IXR, see 7250 IXR QoS policies.

Support for specific parameters and features depends on the chassis type. Local definitions of the policy do not necessarily support all configurations in the global policy. See the NE documentation for more information.

Steps
 
1 

Choose Policies→QoS→SROS QoS→Access Ingress→7210, 7250 and 1830 Access Ingress Policies from the NFM-P main menu. The 7210, 7250 and 1830 Access Ingress Policies form opens.

2 

Click Create, or choose a policy and click Properties. The 7210, 7250 and 1830 SAP Access Ingress Policy (Create|Edit) form opens.

3 

Configure the required parameters on the General tab.

To avoid deployment errors, configure the Number of QoS Classifiers parameter to coordinate with the system resource profile settings for the NE. See System resource profile in Chapter 6, Device support . The combined SAP-based allocations must not exceed the system allocations. See the NE documentation for more information.

For supporting 7210 SAS-Mxp NEs, table-based ingress classification is available using an assigned FC Meter Map policy. You must set the Use SVC Meter Pool to True, and assign an FC Meter Map policy in the Classification Type panel.

You can configure the IPV6 Match Criteria type parameter only when the Allow any IPV6 Match parameter is set to true.

You cannot change the setting of the MAC Match Criteria type, IP Match Criteria type, or IPV6 Match Criteria type parameters when entries exist for that match type. You must delete the entries first, and release the global policy.

You cannot set the IP MAC Match Criteria type parameter to None, or change it from None, when entries exist. You must delete the entries first, and release the global policy.

You cannot change the setting of the IP MAC Match Criteria type parameter when the policy is assigned to an access interface.

When the IP MAC Match Criteria type parameter is set to IP First or MAC first, the Allow any IPV6 Match parameter must be set to false.

4 

If you are configuring a policy for the 7210 SAS-K, select a Dot1p classification policy in the Classification Type panel. See To configure a 7210/7250 Dot1p classification policy for information about 7210 Dot1p classification policies.

The classification policies selected in the Classification Type panel apply only to the 7210 SAS-K. For 7250 IXR classification configuration, you must select an Ingress CoS classification policy in the Ingress CoS Classification panel; see Step 6.

5 

If you are configuring a policy for the 7210 SAS-K, or for table-based classification on supporting chassis types, select a DSCP classification policy in the Classification Type panel. See To configure a 7210/7250 DSCP classification policy for information about 7210 DSCP classification policies.

The classification policies selected in the Classification Type panel apply only to the 7210 SAS-K. For 7250 IXR classification configuration, you must select an Ingress CoS classification policy in the Ingress CoS Classification panel; see Step 6.

6 

If you are configuring a policy for the 7250 IXR, or for table-based classification on supporting chassis types, select a 7250 Ingress CoS classification policy in the Ingress CoS Classification panel. See To configure a 7250 Ingress CoS policy for information about 7250 Ingress CoS policies.

You cannot select a 7250 Ingress CoS policy that contains a 7210/7250 MPLS LSP-EXP policy.

7 

If you are configuring a policy for a 7210 SAS-Mxp that supports 7210 Meter Map policies, perform the following:

  1. Set the User SVC Meter Pool parameter to True. FC-Meter-Map parameters appear on the form.

    The Number of QoS Classifiers parameter supported value is 2.

  2. Select a 7210 FC Meter Map policy in the Classification Type panel. See To configure a 7210 FC Meter Map policy;

  3. Go to Step 16.

8 

Configure ingress meters.

The 7250 IXR NEs use the term “policer” internally, but the NFM-P policy configuration uses the term “meter”. When you configure a 7210, 7250 and 1830 SAP Access Ingress policy for 7250 IXR NEs, meters configured in the policy correspond to policers in 7250 IXR NEs.

The Number of QoS Classifiers parameter, configured in Step 3 , affects the number of meters available.

Perform the following:

  1. Click on the Meter tab.

  2. Select a meter and click Properties, or click Create. The Meter form opens.

  3. Configure the required parameters on the General tab.

    You cannot choose ID values 1 or 11 for user-configured meters; these ID values are used by default meters.

    Note:

    To enable hierarchical ingress policing (H-metering), set the Rate Mode parameter to trTCM (RFC 4115).

  4. Click on the CIR/PIR and Burst Size tabs and configure the required parameters.

  5. Save your changes and close the form.

9 

Configure ingress queues.

The Number of QoS Classifiers parameter, configured in Step 3 , affects the number of queues available.

  1. Click on the Queues tab.

  2. Select a queue and click Properties, or click Create. The Queue form opens.

  3. Configure the required queue identification parameters.

  4. Select a queue management policy in the Queue Management Policy panel. See To configure a 7210 and 7250 Queue Management policy for information about queue management policies.

  5. Select a slope policy in the Slope Policy panel. See To configure a 7210 and 1830 slope policy for information about slope policies.

  6. Configure the scheduling parameters in the Port Parent panel.

  7. Configure the rate parameters in the CIR/PIR panel.

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

  9. Save your changes and close the form.

    Note:

    You can configure queues in the policy anytime, but when the policy is assigned to an interface, the system resource profile for the 7210 SAS NE must allocate sufficient resources to the Queues function. See To configure the global system resource profile on a 7210 SAS or 7250 IXR .

10 

Click on the Forwarding Classes tab.

11 

Select a forwarding class and click Properties, or click Create. The Forwarding Class form opens.

12 

Configure the Forwarding Class parameter, if required.

13 

Map the FC to a queue or meter. Perform one of the following:

  1. Assign a queue or queues to the forwarding class.

    1. Select a queue for each of the required queue types in the Queue panel. To create queues, see Step 9 .

    2. Save your changes and close the form.

  2. Assign a meter or meters to the forwarding class.

    1. Select a meter for each of the required meter types in the Meter panel. To create meters, see Step 4 .

    2. Save your changes and close the form.

You can also select meters or queues by directly entering the meter or queue ID.

14 

Repeat Step 11 to Step 13 for each forwarding class that you need to configure.

15 

Configure match criteria entries.

Note: The Number of QoS Classifiers parameter, configured in Step 3 , affects the maximum number of entries available.

MAC and IP match criteria entries consume NE system resources. The system resource profile for a 7210 SAS NE must be configured appropriately. See System resource profile in Chapter 6, Device support .

Perform any of the following:

  1. Associate forwarding classes with MAC match criteria.

    1. Click on the MAC Match Criteria tab.

    2. Select an entry in the list and click Properties, or click Create. The MAC Match form opens.

    3. Configure the required parameters.

      You can configure the Source MAC, Destination MAC, and Ether Type parameters only when the MAC Match Criteria type parameter is set to Any in Step 3 .

    4. Save your changes and close the form.

  2. Associate forwarding classes with IP or IPv6 match criteria.

    1. Click on the IP Match Criteria tab or IPv6 Match Criteria tab.

    2. Select an entry in the list and click Properties, or click Create. The IP Match or IPv6 Match form opens.

    3. Configure the required parameters.
