–
1000 ms: 1 frame is sent per second. This interval is recommended in fault management.
–
10000 ms: 6 frames are sent per minute.
–
60000 ms: 1 frame is sent per minute.
–
600000 ms: 6 frames are sent per hour.
Select a proper CCM transmission interval to suit the CC application requirement.
l
To configure the priority of CCMs, run the
cc exp
exp-value
command.
If the MPLS-TP network is severely congested and the priority of CCMs is low, CCMs cannot
be sent. Therefore, a proper priority needs to be configured for CCMs based on network
conditions.
Step 4
Perform the following steps to enable CC and CV on the MEP and RMEP. This can prevent
MEPs from generating alarms mistakenly during enabling process.
1.
On the MEP, run:
cc send enable
Sending CC/CV packets is enabled on the MEP.
2.
On the RMEP, run:
cc send enable
Sending CC/CV packets is enabled on the RMEP.
3.
On the MEP, run:
cc receive enable
Receiving CC/CV packets is enabled on the MEP.
4.
On the RMEP, run:
cc receive enable
Receiving CC/CV packets is enabled on the RMEP.

9.2.4 (Optional) Configuring LB for Sections on an LSP
LB is the most common tool used to detect connectivity of MPLS-TP links.
Context
LB is used to monitor the connectivity between a MEP and its RMEP. Unlike CC or CV that is
performed periodically, LB is performed at a specified time.
Commands can be run to trigger LB, and LB packets are used to check the following items:
l
Availability of the remote device
l
Round-trip delay in communication between two MEPs
l
Loss of ping packets
Procedure
Step 1
