Indicates the system assigned serial number.

PW ID

Example: 3

Indicates the PW ID.

PW Type

The parameter value depends on the service type.
  • Ethernet Service: Ethernet, Ethernet Tagged Mode
  • IP over PW: IP PW
  • ATM service whose ATM Connection Type is PVP: ATM n to one VPC cell transport, ATM one to one VPC cell Mode
  • ATM service whose ATM Connection Type is PVC: ATM n to one VCC cell transport, ATM one to one VCC cell Mode
  • ATM service whose ATM Connection Type is Port Transparent: ATM transparent cell transport
  • CES Service: CESoPSN, SATop
  • PTP Clock Service: Ethernet

Specifies the modes in which different types of service packets are encapsulated in PWs.

OAM Status

Enabled, Disabled

Indicates the OAM status. This parameter can be set. The default value is Disabled. In non-IP mode, configure MEG ID, MEP ID, and the peer MEP ID before you enable the OAM function.
  • Enabled: OAM-related operations can be performed.
  • Disabled: OAM-related operations cannot be performed.

MEG ID Type

IP Based, ICC Based, Customer Based

  • IP Based: Indicates the default MEG ID type of PTN equipment. It is used to generate MEG IDs automatically.
  • ICC Based: Indicates the MEG ID type defined by the Y.1731 recommendation.
  • Customer Based: Indicates the MEG ID type used for interconnection with equipment from special vendors.

The MEG ID Type must be the same at the source and the sink ends.

MEG ID

Example: 3

Indicates the MEG ID. MEG ID varies with MEG ID Type.

  • When MEG ID Type is set to IP Based, MEG ID, MEP ID, and RMEP ID are generated automatically.
  • When MEG ID Type is set to ICC Based, MEG ID is a character string with letters and numbers, and contains 1 to 13 bytes.
  • When MEG ID Type is set to Customer Based, MEG ID consists of 96 characters that represent 48 hexadecimal numbers. The default value is a character string consisting of 96 zeros. You can set MEG ID to any character strings that consist of only letters (a-f) and digits (0-9).

MEG Level

0, 1, 2, 3, 4, 5, 6, 7

Indicates the MEG priority. The value 7 indicates the highest priority.

MEP ID

1 to 8191

Indicates the MEP ID. The MEP ID at the source must be the same with the RMEP ID at the sink ends.

RMEP ID

1 to 8191

Indicates the RMEP ID. The RMEP ID at the source must be the same with the MEP ID at the sink ends.

Detection Mode

Adaptive, Manual

Indicates the detection mode.
  • Manual: The frequency set by the user is used to test the connectivity of the PW.
  • Adaptive: The frequency of the received packets is used to test the connectivity of the PW.

CC Status

Stop, Start

Indicates the current status of the CC check.

CC Packet Priority

0, 1, 2, 3, 4, 5, 6, 7

Sets and Indicates the CC packet priority. Value 0 indicates the lowest priority, and value 7 indicates the highest priority.

CC Packet Interval

Example: 3.33ms

Sets and Indicates the interval of transmitting detection packets.

Lock Status

Unlock, Lock

specifies whether the LCK function is enabled. If this function is enabled, when a TST test that interrupts services is performed, LCK packets will be sent to notify users that the service interruption is caused by the TST test.

Local Status

Initialized, Near-End Available, Near-End Defect Available, Near-End Defect Unavailable, Near-End Unavailable

Indicates the local PW operating status.

Local Defect Type

dServer, dPeerME, dLOCV, dExcess, dUnExpPer, dUnExpMeg, dUnExpMep

Indicates the local PW defect type.

Local Disable Duration(ms)

0 to 300000

Indicates the duration of the disable status of the PW.

Local Disable Duration indicates the duration when the PW is unavailable.

Local Defect Location

Example: 192.168.11.1

Indicates the local PW defect location.

Local Defect Location identifies the location of the defect in the network by using the IP address.

Remote Status

Remote Available, Remote Defect Available, Remote Defect Unavailable, Remote Unavailable, Initialized

Indicates the remote PW operating status.

Remote Defect Type

dServer, dPeerME, dLOCV, dExcess, dUnExpPer, dUnExpMeg, dUnExpMep

Indicates the remote PW defect type.

Remote Disable Duration(ms)

0 to 300000

Indicates the duration of the disable status of the PW.

Remote Disable Duration indicates the duration when the PW is unavailable.

Remote Defect Location

Example: 192.168.11.1

Indicates the remote PW defect location.

Remote Defect Location identifies the location of the defect in the network by using the IP address.

SD Threshold(%)

0 to 100

Indicates and specifies the SD threshold.

SF Threshold(%)

0 to 100

Indicates and specifies the SF threshold.

SD ≤ SF

LSR ID to be Received

Example: 10.10.10.1

Specifies the LSR ID on the peer end.

For the MSPW, specify the LSR ID of the MS PW sink node.

NOTE:

You can configure the LSR ID to be Received only when the OAM is disabled

PW ID to be Received

Example: 111

For the MSPW, specify the ID of the PW that is connected to the MS PW sink node.

NOTE:

You can configure the PW ID to be Received only when the OAM is disabled

LM Packet Mode

Standard Mode, Huawei Mode

Indicates the LM packet mode for case-shaped transport equipment when the equipment interconnects with other types of equipment.

  • Set LM Packet Mode to Huawei Mode when case-shaped transport equipment interconnects with subrack-shaped transport equipment. The LM packet format of case-shaped transport equipment is different from that specified in protocols.
  • Set LM Packet Mode to Standard Mode when case-shaped transport equipment interconnects with CX or other case-shaped transport equipment.

GAL Enable Status

Enabled, Disabled

Generic associated channel labels (GALs) identify OAM packets, and are disabled by default.

GAL Mode

Y.1711, RFC5586

Default: RFC5586

Indicates the GAL mode that is used to achieve MPLS-TP OAM on NEs. The options are as follows:
  • Y.1711: The NE can interwork with PTN NEs to achieve MPLS-TP OAM.
  • RFC5586: The NE can interwork with RTN and MSTP NEs to achieve MPLS-TP OAM.
