A 7210 SAP access egress policy defines remarking and SAP egress queue parameters for traffic egressing the switch into a service.

For packets, the policy defines SAP-based remarking values using an assigned 7210 remarking policy.

For SAP-based egress queues, the policy defines:

• rate parameters

• scheduling priority values and weights

• slope parameters and burst size values, using an assigned queue management policy or slope policy

Egress queues are mapped to forwarding classes. For 7210 SAS-Mxp, 7210 SAS-R, and 7210 SAS-X devices, the mapping is static and not user-configurable. The mapping for these devices is not displayed in the NFM-P. The following table shows the system-defined mapping.

Table 50-8: 7210 SAS system-defined FC-to-queue mapping

Forwarding class	Queue ID
nc	8
h1	7
ef	6
h2	5
l1	4
af	3
l2	2
be	1

For the 7210 SAS-K, the FC-to-queue mapping is user-configurable. You must explicitly enable queues in policies distributed to the 7210 SAS-K, except for Queue 1 which is enabled by default. Only queues that are applicable are available for mapping to FCs.

The 7210 SAP access egress policy is assigned to L2 access interfaces on VPLS and VLL services, and to L3 access interfaces on IES and VPRN services. You can also assign the policy to destination L2 interfaces on mirror services. The 7210 SAP access egress policy is SAP-based, not port-based, and applies policy definitions only on the interfaces to which it is assigned. The policy is assigned to interfaces in the following procedures, according to the service type:

• To assign ingress and egress QoS policies to a VLL L2 access interface on a 7210 SAS site for VLL

• To assign ingress and egress QoS policies to a VPLS L2 access interface on a 7210 SAS site for VPLS

• To assign ingress and egress QoS policies to an IES L3 access interface on a 7210 SAS site for IES

• To assign ingress and egress QoS policies to a VPRN L3 access interface on a 7210 SAS site for VPRN

• To create an L2 access interface on a destination site for mirror services

The NFM-P assigns a default 7210 SAP access egress policy to an interface unless a user-configured policy is explicitly assigned. The default policy (policy ID 1) cannot be altered or deleted.

The 7210 SAP access egress policy is supported on the 7210 SAS-K, 7210 SAS-Mxp, 7210 SAS-R, and 7210 SAS-X. Support for specific parameters and features varies, depending 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.

Note: For the 7210 SAS-Mxp, 7210 SAS-R, and 7210 SAS-X, access egress remarking is either SAP-based or port-based. L3 access egress remarking is always port-based. For the 7210 SAS-Mxp and 7210 SAS-R, L2 access egress remarking is always SAP-based.

For the 7210 SAS-X, to use the values configured in a 7210 SAP access egress policy for SAP-based remarking, you must enable the SAP QoS Marking parameter on the port properties form for access and hybrid ports; see To configure Ethernet ports .
