Querying an MPLS PWQuerying QoS-Related Parameters of an MPLS PW

When you create a service, a PW is created. The PWs are not bundled with services, however, are not displayed. Hence, you need to query these PWs in the PW Management interface. In the PW Management interface, you can query all PWs created on the equipment, and parameters such as PW type, QoS parameters, OAM parameters and bearer tunnel.

Navigation Path

For RTN NEs, in the NE Explorer, click the NE and choose Configuration > MPLS Management > PW Management from Function Tree.

Buttons

Button	Description
View Policy Details	Query the QoS policy of the PW.
Query	Query all MPLS PWs created on the NE. NOTE: You must complete the creation of an MPLS PW during creating of a service.

Short-Cut Menu

Short-Cut Menu	Description
Browse Current Alarms	Browse current alarms of the PW.
Browse Historical Alarms	Browse history alarms of the PW.
Alarm Suppression	When an alarm is suppressed for a PW, the alarm is not reported either on the NE or on the U2000 Web LCT.
Browse Performance	Browse the performance events to check for the abnormal status that does not generate alarms on the PW. The maintenance personnel then can take proper measures to avoid faults.
Performance Statistics Management	Browse the common performance events of PW to check for the abnormal status that does not generate alarms on the PW. The maintenance personnel then can take proper measures to avoid faults.
PW Ping Test	By performing a Ping test on the PW, you can check the PW status.
Disable	Disable the current PW.
Enable	Enable the current PW.
Switch to Y.1711	Switches the OAM recommendation of a PW to the Y.1711 recommendation.
Switch to Y.1731	Switches the OAM recommendation of a PW to the Y.1731 recommendation.
Query PW-Down Cause	Query the fault cause when the PW is not normally created, and the services are unavailable.
Query Actual Negotiation Results	Query the actual negotiation results between the source and sink node.

Parameters

**Table 1** Descriptions of the parameters for PW
Field	Value	Description
Index	Example: 1	Indicates the PW index. The PW in alarm can be located according to the Monitored Object value.
PW ID	Example: 5	Display the PW ID.
PW Status	Enabled, Disabled	Display the enable state of the PW.
PW Signaling Type	Static, Dynamic	Display the PW signaling type. If PW Signaling Type is set to dynamic, the system automatically allocates the PW ingress label and PW egress label. If PW Signaling Type is set to static, set the PW ingress label and PW egress label manually.
PW Type	Example: SATop	Display the PW service type.
PW Direction	Bidirectional, Unidirectional	Display the direction of the PW. Currently, the static unicast PW should only be bidirectional.
PW Encapsulation Type	MPLS	Display the PW encapsulation type.
PW Incoming Label/Source Port	Example: 35	Display the PW ingress label. Indicates the label that enters the PW.
PW Egress Label/Sink Port	Example: 36	Display the PW egress label. Indicates the label that exits the PW.
Peer LSR ID	Example: 192.168.0.3	Specifies the LSR ID for the peer node of a PW in the case of single-segment PWs. Specifies the LSR ID for the node of the peer PW in the case of multi-segment PWs.
Local Operating Status	Example: Up	Display the local Operating status of the PW.
Remote Operating Status	Example: Down	Display the remote Operating Status of the PW.
Overall Operating Status	Up, Down	Display the overall Operating Status of the PW. Overall Operating Status is up only when Local Operating Status and Remote Operating Status are up.
Tunnel Type	MPLS	Indicates or specifies the type of the tunnel.
Tunnel	Example: 16	Specifies the tunnel for carrying a PW. NOTE: When you specify an MPLS tunnel for carrying a PW at an NE, the specified tunnel must be an ingress unicast tunnel.
Tunnel No	Example: 1	Display the ID of the ingress tunnel that carries the bidirectional PW.
Egress Tunnel	Example: 1	Displays the ID of the egress tunnel that carries the bidirectional PW.
Deployment Status	Deployed, Undeployed	Displays the current deployment state of a PW.
Tunnel for Auto Selection	For example: Static MPLS Tunnel; Dynamic RSVP TE Tunnel; IP Tunnel, GRE Tunnel	Displays the tunnel automatic selection policy when Tunnel Selection Mode is Auto Select. The tunnel types in the value are separated with a comma and the priority of the tunnels of different types decreases from left to right. RTN NEs do not support set this parameter.
Query Actual Bandwidth	Checked, Unchecked	When this parameter is selected, the actual effective bandwidth is queried. When this parameter is not selected, the configured bandwidth is queried. The RTN NEs do not support the query of actual bandwidth.
Oam Recommendation	For example: MPLS OAM(Y.1711)	Displays Oam Recommendation.
Switching Triggered by Packet Loss Rate	Enabled, Disabled	Specifies whether to trigger switching when the packet loss rate exceeds thresholds. After you set Switching Triggered by Packet Loss Rate to Enabled, SD Threshold and SF Threshold are available. If the packet loss rate on a PW exceeds the preset SD or SF threshold, tunnel protection switching is triggered.
SD Threshold	1.0E-2, 1.0E-3, 1.0E-4, 1.0E-5, 1.0E-6	Indicates the threshold of SD caused by packet loss.
SF Threshold	1.0E-2, 1.0E-3, 1.0E-4, 1.0E-5, 1.0E-6	Indicates the threshold of SF caused by packet loss.
