display mpls oam l2vc

Function

The display mpls oam l2vc command displays configurations and the status of MPLS OAM that monitors PWs.

Format

display mpls oam l2vc { all | peer-ip peer-ip-value vc-id vc-id-value vc-type vc-type-value } [ verbose ]

Parameters

Parameter	Description	Value
all	Displays MPLS OAM information about all PWs.	-
peer-ip peer-ip-value	Specifies the destination IP address of an L2VC.	The value is in dotted decimal notation.
vc-id vc-id-value	Specifies the ID of an L2VC.	The value is an integer ranging from 1 to 4294967295.
vc-type vc-type-value	Specifies the encapsulation type of an L2VC.	Encapsulation types supported: Other encapsulation types: cep: This encapsulation type is used for CEP services. ethernet: This encapsulation type is used when Ethernet packets do not carry VLAN information. ip-interworking: This encapsulation type is used for interworking between Huawei devices. ip-layer2: This encapsulation type is used for interworking between Huawei devices and non-Huawei devices. vlan: This encapsulation type is used when Ethernet packets carry VLAN information.
verbose	Displays detailed information.	-

Usage Guidelines

Usage Scenario

After configuring MPLS OAM to monitor PWs, you can run the display mpls oam l2vc command to view MPLS OAM information. You can view MPLS OAM information about multiple PWs or a specified PW.

Prerequisites

MPLS OAM have been configured to monitor PWs using the mpls oam l2vc command.

Example

The actual command output varies according to the device. The command output here is only an example.
