1.1 MPLS OAM Configuration Commands
1.1.1 mpls oam
Syntax
mpls oam
undo mpls oam
View
System view
Parameters
None
Description
Use the mpls oam command to enable OAM globally.
Use the undo mpls oam command to disable OAM.
When you execute the mpls oam command, the system will clear all the current OAM configurations. As a result, all OAM configuration query operations do not take effect.
OAM instances can be configured only after the OAM function is enabled globally.
By default, OAM is disabled.
Examples
# Enable OAM globally.
<H3C> system view
[H3C] mpls oam
1.1.2 mpls oam ingress
Syntax
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 } ]
undo mpls oam ingress { all | lsp-name lsp-name }
View
System view
Parameters
lsp-name: Name of the static LSP, which is used for OAM configuration on the ingress node.
lsp-id: ID of the static LSP, which is used for setting trail termination source identifier (TTSI).
type: Specifies the type of OAM verification packet: connectivity verification (CV) or fast failure detection (FFD). By default, the packet type is CV.
ffd-fre: Transmission frequency only specific to FFD packet, which defaults to 100ms.
share: Sets the backward LSP to share LSP.
rev-lsp-name: Name of the reverse static LSP. For a share backward LSP, the name is not specified.
Description
Use the mpls oam ingress command to configure OAM and modify OAM parameters for a specified static LSP.
Use the undo mpls oam ingress command to remove the OAM instance of the specified LSP. If the all argument is specified, the system will clear all configurations on the ingress node.
& Note:
The ingress node and the egress node should have the same backward LSP configuration: share or exclusive.
Examples
# Configure OAM on the ingress node.
<H3C> system view
[H3C] mpls oam ingress lsp-name pe1-pe2 lsp-id 1 type ffd backward-lsp lsp-name pe2-pe1

Parameters
all: Specifies to verify all the OAM-enabled LSPs.
lsp-name: Name of the OAM-enabled LSP to be verified.
Description
Use the mpls oam ingress enable command to enable the OAM verification function for a specified LSP or all LSPs on the ingress node. If OAM is disabled, the configuration of the LSP will be reserved, that is, OAM instance configured for the LSP will be retained.
Use the undo mpls oam ingress enable command to disable the OAM verification function.
By default, the OAM verification function is disabled.
Examples
# Enable the OAM verification function on the ingress node.

Parameters
protect-id: ID of the protection group.
w-lsp-name: Name of the primary LSP.
p-lsp-name: Name of the secondary LSP.
holdofftime: Protection switching delay at the step of 100 ms. The default value is 0 ms and the maximum value is 10s.
mode: Specifies a switch back mode (after the primary LSP recovered from a fault, data flows will switch from the secondary LSP back to the primary LSP): revertive or non-revertive. The default mode is non-revertive.
wtrtime: Switch back time specific to revertive mode at the step of 30s. By default, it is 24 (12 min).
Description
Use the mpls protect-switch command to create a protection group.
Use the undo mpls protect-switch command to delete a protection group.
& Note:
In a protection group, the primary and secondary LSPs must have the same FEC, but different egress labels.
Examples
# Create a protection group.

Parameters
lsp-name: Name of the LSP.
dest-addr: Destination IP address.
addr-mask: Mask.
mask-length: Mask length.
next-hop-addr: IP address of the next hop.
out-label-value: Egress label value.
backup: Configures a secondary LSP.
Description
Use the static-lsp ingress command to configure a static LSP or a secondary static LSP.
Use the undo static-lsp ingress command to remove the configuration.
& Note:
The secondary static LSP only takes effect after the protection group is configured. If the protection group is not specified, no entry will be generated by the secondary static LSP.
Examples
# Configure a secondary static LSP.

Parameters
-c count: Number of Echo request packets sent.
-s packet-size: Length of the sent packet, in byte.
-t time-out: Time to wait for Echo response, in millisecond.
-h ttl-value: TTL value of the sent Echo request packet.
-v: Detailed information.
-a source-ip: Source IP address of the sent Echo request packet.
-exp exp-value: EXP value of the sent Echo request packet.
-m interval: Interval to send the next packet, in millisecond.
-r reply-mode: Response mode, in the range of 1 to 2, with 1 being no response and 2 being response with the IPv4/IPv6 UDP packet.
ipv4 dest-address dest-mask: Destination IP address and mask of LDP IPv4 LSP.
ip-address: Destination address in IP header of the MPLS Ping packet, with a prefix of 127/8.
Description
Use the ping lsp command to receive and send Echo request and response packets over an LSP. Its functions are similar to the common ping command. The difference is that the former command is executed on an LSP.
Examples
# Configure LSP ping.
<H3C> system-view
