V-UNI Ingress Policy

New

Click New to create a V-UNI ingress policy.

Query

Select the V-UNI ingress policy for the query. Click the Applied Object tab and click Query. Information on the service that uses this policy is displayed.

Delete

Select the V-UNI ingress policy to be deleted, Click Delete.

Apply

Configurations take effect only by clicking Apply after V-UNI ingress policy parameters are modified.

Copy

Traffic Classification Rules

Modify the classification rules of the traffic.

Colorize

Mark color for the selected traffic classification.

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.

Traffic Classification Bandwidth Sharing

Disabled, Enabled

Set the bandwidth sharing of the traffic classification.

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

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, 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 need not be processed exceptionally.

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

PIR (kbit/s)

Example: 1000

CBS (bytes)

Example: 20000

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: 20000

Set the peak burst size. This parameter can be set only when Bandwidth Limitation is set to Enabled.

Trail Drop Threshold (256 bytes)

Example: 200

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.

Color Mode

Color-blind, Color-aware

Set the coloration mode.

Color-blind: Packets are discarded without recognition of the color.

Color-aware: Packets are scheduled according to the color.

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 discard lower threshold, no packets are discarded. When the queue length is higher than the discard lower threshold but lower than the discard upper threshold, packets are discarded randomly. When the queue length is higher than the discard upper threshold, all packets are discarded. Set either Tail Drop Threshold or Service WRED Policy, but not both.

Traffic Classification ID

Example: 2

Set and display the ID of the traffic classification.

Traffic Classification Rules

Example: Protocol Type: TCP

Display the rule for traffic classification. Click Traffic Classification Rules to modify the rule.

ACL Action

Disabled, Enabled

Set the ACL of the traffic classification. The ACL is used to classify the received packets to decide whether to forward or discard packets.

CAR Policy

Example: car_test

Set the CAR policy.

Logical Relation Between Matched Rules

And, Or

Set the logical relation between matched rules.

And indicates that the matched rules should be applicable to all match types. Or indicates that the matched rules should be applicable to the selected match types.

Match Type

Source IP Address, Destination IP Address, Source MAC Address, Sink MAC Address, Protocol Type, Source Port, Destination Port, ICMP Packet Type, DSCP Value, IP Precedence Value, C-Vlan ID, C-Vlan Priority, S-Vlan ID, S-Vlan Priority, DEI

Click Add to add a row for a new match type.

Match Value

0 to 4095

Set the match value of each match type.

Wildcard

0 to 4095

Set the wildcard of the match value. Adopt 0 for strictly matched bits, and 1 for unconcerned bits.

Packet Color

Red, Yellow, Green

Mark packets in red, yellow or green. The packets marked in red are discarded with the highest priority.

Handling Mode

Discard, Pass, Remark

Set the mode in which packets are handled.

• Discard: Discard packets.
• Pass: Forward packets.
• Remark: Re-mark packets by the CoS and colors.

Relabeled CoS

CS7, CS6, EF, AF4, AF3, AF2, AF1, BE

Re-set the packet CoS when Handling Mode is set to Remark.

Relabled Color

Red, Yellow, Green

Re-mark color for packets when Handling Mode is set to Remark.

Service ID

Example: 123

Query the ID of the service object to which the policy is applied.

Interface

Example: 3-ETFC-3(PORT-3)[23]

Query the interface to which the policy is applied.

V-UNI ID

Example: 1

Query the V-UNI 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.
