Configure the V-UNI egress policy at the access side of the equipment to perform the QoS control over the egress traffic.

Navigation Path

For RTN NEs, in the NE Explorer, click the NE and choose Configuration > QoS Management > Policy Management > V-UNI Egress Policy.

Buttons

Button	Description
New	Click New to create a V-UNI egress policy.
Delete	Select the desired V-UNI egress policy and click Delete. NOTE: The policy to be deleted is not used.
Apply	The configuration takes effect only by clicking Apply after the V-UNI egress policy parameters are modified. NOTE: The policy to be modified is not used.
Query	Select the V-UNI egress policy for the query. Click the Applied Object tab and click Query. Information on the service that uses this policy is displayed. NOTE: You must use the V-UNI egress policy to a service.
Copy	Copy the existing V-UNI Egress policy as a new policy.

Parameters

**Table 1** Descriptions of the parameters for V-UNI Egress Policy
Field	Value	Description
Policy ID	Example: 5	Set and display the ID of the policy.
Automatically Assign	Checked, Unchecked	Selects whether the ID is allocated automatically.
Policy Name	64 bytes	Set and display the name of the policy.
WFQ Scheduling Policy	Policy ID-Policy Name For example: 1-WFQ Default Scheduling	Select the configured WFQ scheduling policy in the displayed dialog box. Related parameters in the dialog box are set in WFQ Scheduling Policy. For details, see WFQ Scheduling Policy.
WRR Scheduling Policy	Policy ID-Policy Name For example: 1-WRR Default Scheduling	Selects the configured WRR policy in the displayed dialog box. Related parameters in the dialog box are set in WRR Scheduling Policy. For details, see WRR Scheduling Policy.
CoS	CS7, CS6, EF, AF4, AF3, AF2, AF1, BE	Define the different service classes. CS6-CS7: Indicates the highest service class. The CoS is applicable to transport of signaling. EF: Indicates fast forwarding. The CoS is applicable to the service of little delay and packet loss rate, AF1-AF4: Indicates the guaranteed forwarding. The CoS is applicable to the service that requires a certain rate, but does not limit the delay or jitter. BE: Indicates the traffic that need not be processed exceptionally, such as the audio and video service traffic.
Grooming Policy After Reloading	SP, WRR, WFQ	Sets the grooming policy after reloading: WRR Grooming Algorithm. The WRR grooming algorithm divides each port into several egress queues and grooms the packets in these queues in turn. This algorithm ensures that every queue obtains a certain period of service. SP Queue Grooming Algorithm. packets of key services are placed in higher priority queues, and packets of non-key services (such as email) are placed in lower priority queues. In this way, packets of key services are always transmitted with a higher priority, and packets of non-key services are transmitted during the transmission intervals of key services. WFQ Grooming Algorithm. A fair queue scheduling algorithm based on bandwidth allocation weights. This scheduling algorithm allocates the total bandwidth of an interface to queues, according to their weights and schedules the queues cyclically. In this manner, packets of all priority queues can be scheduled.
Bandwidth Limitation	Disabled, Enabled	The CIR, PIR, CBS, PBS, Tail Drop Threshold and Port WRED Policy can be set only when Bandwidth Limitation is set to Enabled.
CIR (kbit/s)	Example: 1000	Commit the information rate for the service to pass. This parameter can be set only when Bandwidth Limitation is set to Enabled. The CIR and PIR of CS7 should be the same as those of CS6.
PIR (kbit/s)	Example: 1000	Set the maximum rate for the service to pass. This parameter can be set only when Bandwidth Limitation is set to Enabled.
CBS (bytes)	Example: 10000	Set the committed burst size for the traffic to pass in a short time. This parameter can be set only when Bandwidth Limitation is set to Enabled.
PBS (bytes)	Example: 10000	Set the peak burst size. This parameter can be set only when Bandwidth Limitation is set to Enabled.
Trail Drop Threshold (256 bytes)	0 to 4095	Set the tail drop threshold. When the queue length exceeds the tail drop threshold, the tail packets are discarded. Set either Tail Drop Threshold or Service WRED Policy, but not both.
Service WRED Policy	Policy ID-Policy Name Example: 1-WRED policy	After bandwidth limit is enabled, double-click the cell to display a dialog box where you need select the configured service WRED policy. Related parameters in the dialog box are set in Service WRED Policy. For details, see Service WRED Policy. When the queue length is lower than the lower drop threshold, no packets are discarded. When the queue length is higher than the lower drop threshold but lower than the upper drop threshold, packets are discarded randomly. When the queue length is higher than the upper drop threshold, all packets are discarded. Set either Tail Drop Threshold or Service WRED Policy, but not both.
Service ID	Example: 123	Query the ID of the object to which the policy is applied.
Interface	Example: 3-ETFC-3(PORT-3)[23]	Query the interface to which the policy is applied.
Duplicated Policy Name	Example: QoS-test	Select the name of the duplicated policy.
New Policy Name	Example: Test	Set the name of the new policy generated by duplicating another one.
