QoS

In this interface, you can set and query the QoS attributes of the Ethernet service.

Navigation Path

The ETH service requires information in this interface. The navigation paths for the three services are as follows:

In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-Line Service. Then click the QoS tab.
In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-LAN Service. Then click the QoS tab.
In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-AGGR Service. Then click the QoS tab.

Parameters

**Table 1** Descriptions of the parameters for PW
Field	Value	Description
Index	For example: 1	Indicates the PW index. The PW in alarm can be located according to the Monitored Object value.
PW ID	For example: 123	Sets the ID of the PW carrying the Ethernet service.
Direction	Ingress, Egress	Sets the direction of the PW. Ingress indicates the in-coming direction. Egress indicates the out-going direction.
PW Type	Ethernet, Ethernet Tagged Mode	PWs of different types process the borne services differently. For example, the PW in the Ethernet tagged mode attaches the tag on the services on this PW.
Bandwidth Limit	Enabled, Disabled	If this parameter is set to Enabled, the bandwidth is limited according to the set CIR, PIR, CBS, PBS, tail drop threshold and port WRED policy.
Policy	For example: QoS-test	Displays the name of the PW policy.
CIR (kbit/s)	64 to 10000000	Commits the rate for the service. This field can be set after Bandwidth Limit is enabled.
CBS (bytes)	For example: 1024	Sets the maximum traffic size for each burst. The committed burst size should not exceed the maximum packet length.
PIR (kbit/s)	64 to 10000000	Sets the maximum rate for the service. The peak information rate should not be less than the committed information rate. This field can be set after Bandwidth Limit is enabled.
PBS (bytes)	For example: 2048	Sets the maximum traffic size for the excessive burst. The maximum burst size should not be less than the extra burst buffer size.
EXP	0-7, None	Sets the QoS priority labels in an MPLS network. These labels correspond to the eight classes. 0 corresponds to BE. 1 corresponds to AF1. 2 corresponds to AF2. 3 corresponds to AF3. 4 corresponds to AF4. 5 corresponds to EF. 6 corresponds to CS6. 7 corresponds to CS7.
LSP Mode	Uniform, Pipe	Sets and displays the LSP mode. Uniform: The CoS of user packets should be recovered when the tunnel label is stripped. Pipe: The CoS of user packets need not be recovered when the tunnel label is stripped.

**Table 2** Descriptions of the parameters for UNI
Field	Value	Description
Interface	For example: 21-N1P1ETF8-1(Port-1)	Sets the user-side interface.
Direction	Ingress, Egress	Sets the direction of the interface. Ingress indicates the in-coming direction. Egress indicates the out-going direction.
Bandwidth Limit	Enabled, Disabled	If Bandwidth Limit is set to Enabled, the bandwidth is limited according to the set CIR, PIR, CBS, PBS, tail drop threshold and port WRED policy.
Policy	For example: QoS-test	Displays the name of the QoS policy.
CIR (kbit/s)	64 to 10000000	Commits the rate for the service. This field can be set after Bandwidth Limit is enabled.
CBS (bytes)	For example: 1024	Sets the maximum traffic size for each burst. The committed burst size should not exceed the maximum packet length.
PIR (kbit/s)	64 to 10000000	Sets the maximum rate for the service. The peak information rate should not be less than the committed information rate. This field can be set after Bandwidth Limit is enabled.
PBS (bytes)	For example: 2048	Sets the maximum traffic size for the excessive burst. The maximum burst size should not be less than the extra burst buffer size.
Default Forwarding Priority	CS7, CS6,EF, AF4, AF3, AF2, AF1, BE, None	The CoS varies with the values. 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 service. 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: The CoS is applicable to the service that need not be processed exceptionally. Ingress direction is configurable.
Default Packet Relabeling Color	None, Red, Yellow, Green	Labels packets with different colors according to the label information carried with the packets. Ingress direction is configurable.

**Table 3** Descriptions of the parameters for QinQ Link
Field	Value	Description
QinQ Link ID	For example: 5	The ID of the QinQ Link carrying the Ethernet service.
Direction	Ingress, Egress	Sets the direction of the QinQ Link. Ingress indicates the in-coming direction. Egress indicates the out-going direction.
Bandwidth Limit	Enabled, Disabled	If Bandwidth Limit is set to Enabled, the bandwidth is limited according to the set CIR, PIR, CBS, PBS, tail drop threshold and port WRED policy.
CIR (kbit/s)	64 to 10000000	Commits the rate for the service. This field can be set after Bandwidth Limit is enabled.
CBS (bytes)	For example: 1024	Sets the maximum traffic size for each burst. The committed burst size should not exceed the maximum packet length.
PIR (kbit/s)	64 to 10000000	Sets the maximum rate for the service. The peak information rate should not be less than the committed information rate. This field can be set after Bandwidth Limit is enabled.
PBS (bytes)	For example: 2048	Sets the maximum traffic size for the excessive burst. The maximum burst size should not be less than the extra burst buffer size.
Policy	For example: QoS-test	Displays the name of the QoS policy.
