To configure a 7210 and 1830 port access egress policy
Purpose
A 7210 and 1830 port access egress policy defines remarking values and queue rate and scheduling parameters for traffic that egresses the switch toward a service. The policy is assigned to access ports; see To assign QoS policies to a 7210 SAS Ethernet port . Policy definitions are applied to all SAPs on the port.
You can enable or disable remarking in the policy. Remarking is configured per FC, or a 7210 remarking policy is assigned.
You can configure CIR and PIR for up to eight queues, and you can assign queue management policies to define slope and burst size parameters for queues. Queues are mapped to forwarding classes by default; the mapping is not user-configurable.
The NFM-P provides a default 7210 and 1830 port access egress policy (policy ID 1). The default policy cannot be modified or deleted, and policy ID 1 cannot be used by another policy. The default policy specifies dot1p remarking, a default remarking policy, and queue rates set to the port line rate. The default policy is assigned to access ports if no user-configured policy is assigned.
All 7210 SAS chassis types (except the 7210 SAS-K) support the 7210 and 1830 port access egress policy. 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.
Steps
1 |
Choose Policies→QoS→SROS QoS→Access Egress→7210 and 1830 Port Access Egress from the NFM-P main menu. The 7210 and 1830 Port Access Egress Policies form opens. |
2 |
Click Create or choose a policy and click Properties. The Port Access Egress Policy (Create|Edit) form opens. |
3 |
Configure the required parameters on the General tab. The Remarking Type parameter is configurable when the Egress Remark parameter is set to true. |
4 |
Select a remarking policy, if required. See To configure a 7210 remarking policy for information about 7210 remarking policies. Note: A 7210 remarking policy that is assigned to a 7210 and 1830 port access egress policy must be of one of the following types: |
5 |
Configure port access egress queues.
|
6 |
Assign remarking values to forwarding classes.
|
7 |
Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs. End of steps |
