HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
In real world situations, CC and CV are usually used together. Therefore, these two functions
are integrated on the NE80E/40E. Perform the following steps on the MEP and RMEP:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
mpls-tp meg
A MEG is created and the MEG view is displayed.
Step 3 (Optional) Run the following command as needed:
Ensure that the same CCM transmission interval is set on the MEP and RMEP; otherwise, an alarm will be
generated.
l To configure the interval between CCM transmissions, run:
l To configure the priority of CCMs, run:
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.

NOTE
cc interval interval-value
CCM transmission intervals and their application scenarios are as follows:
– 3.3 ms: 300 frames are sent per second. This interval is recommended in protection
switching.
– 10 ms: 100 frames are sent per second.
– 100 ms: 10 frames are sent per second. This interval is recommended in performance
monitoring.
– 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.
cc exp exp-value
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.
On the MEP, run:
cc send enable
Sending CC/CV packets is enabled on the MEP.
On the RMEP, run:
cc send enable
Sending CC/CV packets is enabled on the RMEP.
On the MEP, run:
cc receive enable
