Port Policy

The port policy should be configured to realize the QoS control over ports. In this user interface, you can configure parameters related to the port policy for the QoS management.

Navigation Path

For RTN NEs, in the NE Explorer, choose Configuration > QoS Management > Policy Management > Port Policy from the navigation tree.

Guideline

The port WRED policy must be configured if the WRED policy is required in the case of packet discarding.
You can modify or delete the port policy only when the policy is not applied to the NE.

NOTICE:

If a port policy is already applied to the NE, this operation will cause configuration data loss on the U2000 Web LCT and NEs. Exercise caution when you perform this operation.

Button Description

Button	Description
Copy	Copies the existing port policy as a new policy.
Traffic Classification Rules	Modifies the classification rules of the traffic.
Apply	Applies a new port policy by clicking Apply in the Create Port Policy dialog box and selecting Single NE or Multi NE. If you select Single NE, the port policy only applies to the current NE. If you select Multi NE, the port policy applies to the NEs that you select in the Select NE dialog box.
New	Creates a port policy to control packet traffic.
Delete	Deletes unnecessary port policies. NOTE: The policy to be deleted is not used.
Query	Queries port policy data. Click the Application Object tab and click Query. Port information that uses this port policy is displayed. NOTE: The port policy to be queried is applied to ports on the NE.
Modify	Modifies a port policy selected on the Application Object tab. In the Configure Port dialog box displayed, modify applied port. Then click OK. The dialog box displayed shows the operation is successful, click Close.
Color	Color-codes the selected traffic classification.
Reset	Resets CIR (kbit/s), PIR (kbit/s),CBS (bytes), and PBS (bytes) to be bandwidth unlimited, and resets Tail Drop Threshold (256 bytes) and Port WRED Policy to default values when WRED can be configured and Bandwidth Limitation is Enable.

Parameter Description

**Table 1** Port policy parameters
Parameter	Value	Description
Policy ID	For example: 5	Sets and displays the ID of the policy.
Automatically Assign	Checked, Unchecked	Specifies whether the ID is allocated automatically. NOTE: If you select the Assign Automatically check box, the Policy ID is allocated automatically.
Policy Name	64 bytes	Sets and displays the name of the policy. NOTE: You can apply a WRR scheduling policy when creating a port policy.
Traffic Classification Bandwidth Sharing	Enabled, Disabled	Enabled: The overall traffic of the selected application ports should not exceed the set bandwidth. Disabled: The traffic of one port should not exceed the set bandwidth.
CoS	CS7, CS6, EF, AF4, AF3, AF2, AF1, BE, None	Defines 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, such as the audio and video services. 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 does not need to be processed exceptionally. None: Indicates the service classes are not defined.
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.
Policy Weight (%)	1 to 100	You can set Policy Weight (%) when the Groom Policy After Reloading is WRR.
Bandwidth Limitation	Enabled, Disabled Default: Disabled	Specifies whether to create or delete a queue. To create a queue, set Bandwidth Limitation to Enabled. To delete a queue, set Bandwidth Limitation to Disabled. is set to
Egress Bandwidth Limitation	Enabled, Disabled	The Egress CIR, Egress PIR, Egress CBS, Egress PBS can be set only when Egress Bandwidth Limitation is set to Enabled.
CIR (kbit/s)	For example: 1000	Commits the information rate for the service to pass. This parameter can be set only when Bandwidth Limitation is set to Enabled. The CIR of CS7 and CS6 should be the same as PIR.
Egress CIR (kbit/s)	For example: 1000	Commits the information rate for the service to pass. This parameter can be set only when Egress Bandwidth Limitation is set to Enabled.
PIR (kbit/s)	For example: 1000	Sets the maximum rate for the service to pass. This parameter can be set only when Bandwidth Limitation is set to Enabled.
Egress PIR (kbit/s)	For example: 1000	Sets the maximum rate for the service to pass. This parameter can be set only when Egress Bandwidth Limitation is set to Enabled.
CBS (bytes)	For example: 10000	Sets 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.
Egress CBS (bytes)	For example: 10000	Sets the committed burst size for the traffic to pass in a short time. This parameter can be set only when Egress Bandwidth Limitation is set to Enabled.
PBS (bytes)	For example: 10000	Sets the peak burst size. This parameter can be set only when Bandwidth Limitation is set to Enabled.
Egress PBS (bytes)	For example: 10000	Sets the peak burst size. This parameter can be set only when Egress Bandwidth Limitation is set to Enabled.
Color Mode	Color-blind, Color-aware	Sets the coloration mode. Color-blind: Packets are discarded without recognition of the color. Color-aware: Packets are scheduled according to the color. Color-aware is not supported now.
Packet Color	Red, Yellow, Green	Marks packets in red, yellow or green. The packets marked in red are discarded with the highest priority.
Processing Mode	Discard, Pass, Remark	Set the mode in which packets are handled. Discard: Discard packets. Pass: Forward packets. Remark: Reset the packet CoS.
Re-Mark CoS	-	Resets the packet CoS when Handling Mode is set to Remark.
Re-Mark Color	-	Re-marks color for packets when Processing Mode is set to Remark.
Tail Drop Threshold (256 bytes)	For example: 200	Sets the tail drop threshold. Tail drop threshold refers to the percentage of the buffer space used by a queue to the total buffer size. When the length of the queue exceeds the value that is equal to the tail drop threshold multiplied by the buffer size, all subsequent packets are dropped. You can set either Tail Drop Threshold or Port WRED Policy, but not both. In the case of RTN 910/950, this parameter is not supported.
