PW

In this user interface, you can configure and query the parameters related to the PW information of the ATM service.

Navigation Path

In the NE Explorer, select an NE and choose Configuration > ATM Service Management from the Function Tree. Then, click the PW tab.

Parameters

**Table 1** Descriptions of the parameters for Basic Attributes
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	Sets the ID of the PW.
Working Status	Working, Protection	Display the working status.
PW Status	Example: Enabled	Display the enable state.
PW Signaling Type	Static, Dynamic	Sets the methods of creating a PW and distributing the PW label. Dynamic: The LDP protocol is used to distribute the PW label. If you select Dynamic, PW Ingress Label and PW Egress Label cannot be set. Static: The PW label is distributed manually.
PW Type	ATM n to one VCC cell transport, ATM one-to-one VCC Cell Mode, ATM n to one VPC cell transport, ATM one-to-one VPC Cell Mode	Sets the PW encapsulation type. The PW type corresponds to the connection type. In the case of the PVP and PVC connections, two encapsulation types are available, that is, 1:1 and N:1.
PW Direction	Bidirectional	Sets the direction of the PW.
PW Encapsulation Type	MPLS	Sets the PW encapsulation type. When the PW Encapsulation Type is set to MPLS, the MPLS, IP, and GRE tunnels are supported.
PW Incoming Label	16 to 1048575	Sets the PW label attached on the packet header when the service is transmitted from the source to the sink, and encapsulated in the PW.
PW Outgoing Label	16 to 1048575	Sets the PW label attached on the packet header when the service is transmitted from the sink to the source, and encapsulated in the PW.
Peer LSR ID	Example: 1.1.1.2	Sets the LSR ID of the destination.
Tunnel Type	MPLS, IP, GRE	Sets the type of the tunnel.
Tunnel	Example: 5	Displays the tunnel ID.
Ingress Tunnel	Example: 55	Displays the ingress tunnel that carries the pw.
Egress Tunnel	Example: 1	Displays the ID of the egress tunnel.
Local Operating Status	Example: Common Fault	Displays the local running status of PW after you click Query.
Remote Operating Status	Example: Common Fault	Displays the remote running status of PW after you click Query.
Overall Operating Status	Up, Down	Displays the compositive running status of PW after you click Query.
Deployment Status	Deployed, Undeployed	Displays the deployment status.
Automatic Tunnel Selection Policy	For example: Static MPLS Tunnel	When Tunnel Selection Modeis set to Auto Select, the U2000 Web LCT selects automatically the tunnel for carrying a PW based on the tunnel priority set in Tunnel Automatic Selection Policy.

**Table 2** Descriptions of the parameters for QoS and Advanced Attributes
Tab	Field	Value	Description
QoS	PW ID	Example: 5	Sets the ID of the PW.
	Index	Example: 1	Indicates the PW index. The PW in alarm can be located according to the Monitored Object value.
	Direction	Ingress, Egress	Sets the direction of the PW. Ingress: Indicates the direction in which the PW enters a network. Egress: Indicates the direction in which the PW exits a network.
	Bandwidth Limit	Enabled, Disabled	Enables or disables the bandwidth limit.
	CIR (kbit/s)	64 to 10000000	Sets the committed bandwidth of the PW.
	CBS (bytes)	-	This parameter is not supported.
	PIR (kbit/s)	64 to 10000000	Sets the peak bandwidth of the PW.
	PBS (bytes)	-	This parameter is not supported.
	EXP	0 to 7, None	Sets the priority flag of the PW.
	Policy	Example: 2(Voice)	Selects the QoS policy of the PW.
	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.
Advanced Attributes	PW ID	Example: 5	Sets the ID of the PW.
	Index	Example: 1	Indicates the PW index. The PW in alarm can be located according to the Monitored Object value.
	Control Word	Must use, No use	Displays that the control word must be used. In an MPLS PSN network, the control word carries the packet information.
	Control Channel Type	CW, None	Sets the type of the control channel.
	VCCV Verification Mode	Ping, None	Sets the verification of the VCCV. You can verify the connectivity of the PW.
	Max. Concatenated Cell Count	1 to 28	Sets the maximum number of concatenation cells.
	Packet Loading Time (us)	Example: 1000	Sets the packet loading time.
