[ private | share ] ] command on the egress node to configure OAM parameters
for the LSP to be verified.
z
Execute the display mpls oam egress [ all | lspname lsp-name ] command to
display OAM parameters configured in step 1.
z
Execute the mpls oam egress enable [ all | lsp-name lsp-name ] command to
enable the MPLS OAM function.
1.5.3 Abnormal Verification Occurs on the Egress Node
I. Symptom
The network works properly. When you execute the display mpls oam egress [ all |
lspname lsp-name ] verbose commandon the egress node, the defect-sate field
displays dLocv or dUnknown.
II. Solution
The reason for this problem may come from:
z
The ingress node does not enable OAM.
z
The ingress LSR ID and LSP ID of the LSP to be verified are not configured rightly
on the ingress node and the egress node.
z
OAM parameters like verification packet type and transmission frequency
configured on the ingress node and the egress node are not consistent.
To solve this problem, you can:
z
When you execute the display mpls oam ingress [ all | lsp-name lsp-name ]
verbose command, the Enable-state field displays Manual disable, meaning that
the ingress node does not enable OAM. In this case, you should execute the mpls
oam ingress enable [ all | lsp-name lsp-name ] command to enable OAM on the
ingress node.
z
If OAM is enabled on the ingress node, execute the display mpls oam ingress
[ all | lsp-name lsp-name ] verbose command and the display mpls oam egress
[ all | lspname lsp-name ] verbose command to display the OAM configuration for
the ingress node and the egress node respectively. If the ingress LSR ID and LSP
ID of the LSP to be verified, verification packet type and transmission frequency
are inconsistent, use the corresponding configuration command to configure them
properly and reenable OAM.
1.5.4 The Defect State of the Ingress Node is Different from that of the Egress
Node
I. Symptom
When you execute the display mpls oam egress [ all | lsp-name lsp-name ] verbose
command on the egress node, the Defect-sate field displays dLocv; while you execute
