7210 SAS QoS policies
General Information
The NFM-P provides QoS policies that are specific to 7210 SAS NEs. Some of these policies also apply to 7250 IXR devices, as indicated by the menu name of the policy. QoS policy information that is specific to the 7210 SAS may not necessarily apply for other devices.
QoS policies for the 7210 SAS accommodate multiple different 7210 SAS chassis types. See 7210 SAS in Chapter 6, Device support for more information about 7210 SAS chassis types. Not all chassis types support all policies, or all configurations within a policy. For information about chassis support for a specific policy, see Table 50-7, 7210 SAS QoS policies.
For some 7210 SAS QoS policies and functions, device system resources must be appropriately allocated. See System resource profile in Chapter 6, Device support and the NE documentation for more information.
Some 7210 SAS QoS functions and settings are not configured within the policy framework. Instead, they are configured as device or port properties, or during SAP configuration. For an overview of the tasks required to configure QoS on 7210 SAS NEs using the NFM-P, see Sample QoS configuration on the 7210 SAS .
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.
On supporting 7210 SAS NEs, you can override the settings for queues in port access egress policies that are assigned to access ports; see To configure QoS policy overrides on port access egress queues for a 7210 SAS.
A GQP can be used to assign 7210 and 1830 SAP access ingress policies and 7210 SAP access egress policies to access interfaces; see To configure a Generic QoS Profile. GQPs are assigned using the XML API.
When a GQP is used to assign ingress and egress policies to 7210 SAS NEs that do not support QoS policy overrides, an API may be used to provide GQP overrides that change QoS values (CIR, PIR, CBS, MBS). The API creates a new “dynamic” local policy that is outside the NFM-P policy management. Local policy forms remain visible in the NFM-P GUI, and display the Policy Mode parameter, set to dynamic. This indicates that the QoS values are set by the GQP override API, and not from the GUI, CLI, or OSS.
See the 7210 SAS documentation for more information about 7210 SAS QoS and QoS policies.
Table-based ingress classification on the 7210 SAS
The NFM-P supports the configuration of table-based ingress classification on supporting 7210 SAS NEs. When table classification is enabled, ingress DSCP bits are mapped to FCs and profiles using hardware tables instead of CAM resources. The DSCP mappings are configured in a 7210/7250 DSCP classification policy.
You can enable table-based ingress classification for the following:
-
L2 interfaces on VPLS and VLL Epipe services. The 7210/7250 DSCP classification policy is assigned to the SAP Access Ingress policy on the interface.
-
L3 interfaces on IES and VPRN services. The 7210/7250 DSCP classification policy is assigned to the SAP Access Ingress policy on the interface.
-
RVPLS on L3 interfaces. The 7210/7250 DSCP classification policy is assigned to the interface using the Routed VPLS tab of the properties form for the interface. On the form, the 7210/7250 DSCP classification policy is called the Routed Override QoS Policy.
-
Ethernet ports. The 7210/7250 DSCP classification policy is assigned to the port using the Policies tab of the port properties form. When table-based classification is enabled on a port, all SAPs on the port use the 7210/7250 DSCP classification policy assigned to that port. You can configure a default FC for ingress packets that do not have a DSCP value.
See the NE documentation for more information about table-based classification.
Workflow to configure table-based DSCP ingress classification
The following workflow outlines the basic steps required to configure table-based ingress DSCP classification.
1 |
Configure a 7210/7250 DSCP classification policy; see To configure a 7210/7250 DSCP classification policy. Distribute the policy to the required NEs. |
2 |
If you are configuring table-based ingress classification on interfaces, assign the 7210/7250 DSCP classification policy to a 7210, 7250 and 1830 SAP Access Ingress policy; see To configure a 7210, 7250, and 1830 SAP Access Ingress policy. Distribute the policy to the required NEs. |
3 |
Configure table-based ingress classification on interfaces, and assign the 7210, 7250 and 1830 SAP Access Ingress policy from Stage 2 to those interfaces. See the relevant procedure for the service type:
|
4 |
Configure table-based ingress classification for RVPLS on L3 interfaces, and assign the 7210/7250 DSCP classification policy from Stage 1 to those interfaces. See the relevant procedure for the service type:
|
5 |
Configure table-based ingress classification for Ethernet ports, and assign the 7210/7250 DSCP classification policy from Stage 1 to those ports. See To assign QoS policies to a 7210 SAS Ethernet port. |

Notes:
The 7210 SAS-M (in network mode), 7210 SAS-Mxp, 7210 SAS-R,7210 SAS-S, 7210 SAS-Sx, 7210 SAS-T (in network mode), and 7210 SAS-X support 7210 and 1830 network policies on network interfaces. The policy must be of network interface type.
The 7210 SAS-K, 7210 SAS-Mxp, 7210 SAS-R and 7210 SAS-X do not use scheduler policies. Egress scheduling for these devices is defined by the port bandwidth and by user-configured settings in access egress and network queue policies, port properties, and SAP configuration. See Sample QoS configuration on the 7210 SAS in Chapter 70, Service management and QoS.
