display mpls oam egress

Function

The display mpls oam egress command displays the status and the configuration of an OAM-enabled LSP on the egress.

Format

display mpls oam egress { all | lsp-name lsp-name | lsr-id ingress-lsr-id tunnel-id tunnel-id } [ verbose ]

Parameters

Parameter	Description	Value
all	Displays the status and configurations of all OAM-enabled LSPs on the egress.	-
lsp-name lsp-name	Specifies the name of an LSP.	The value is a string of 1 to 19 characters, spaces not supported. If quotation marks are used at both ends of an entered character sting, you can enter spaces in the string.
lsr-id ingress-lsr-id	Specifies the LSR ID of the ingress.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

To view the status and the configuration of an OAM-enabled LSP on the egress, run the display mpls oam egress command. The command output does not include packet statistics about OAM instances.

Example

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

# Display OAM information about the LSP with the LSR ID and tunnel ID set to 1.1.1.1 and 100 on the egress, respectively.
