1.5 Troubleshooting MPLS OAM

1.5.1 Failure to Enable OAM on the Ingress Node

I. Symptom
When you execute the mpls oam ingress enable [ lsp-name lsp-name ] command on
the ingress node, the message "% Warning: Invalid LSP name." displays.
II. Solution
According to the message, you will see that the OAM parameters for the ingress node
are not configured rightly. To solve the problem, you can:
Execute the mpls oam ingress lsp-name lsp-name lsp-id lsp-id [ type { cv | ffd
[ frequency ffd-fre ] } ] [ backward-lsp share | lsp-name rev-lsp-name ]
command on the ingress node to configure OAM parameters for the LSP to be
verified.
Execute the display mpls oam ingress [ all | lsp lsp-name ] command to display
the configured OAM parameters.
Execute the mpls oam ingress enable [ all | lsp-name lsp-name ] command to
enable the MPLS OAM function.

1.5.2 Failure to Enable OAM on the Egress Node

I. Symptom
When you execute the mpls oam egress enable [ lspname lsp-name ] command on
the egress node, the message "% Warning: Invalid LSP name." displays.
II. Solution
According to the message, you will see that the OAM parameters for the egress node
are not configured rightly. To solve the problem, you can:
Execute the mpls oam egress lsp-name lsp-name lsr-id ingress-lsr-id lsp-id
lsp-id } type { cv | ffd [ frequency ffd-fre ] } ] [ backward-lsp rev-lsp-name
