Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the rules for
generating MIPs. cfd mip-rule { explicit | default }
service-instance instance-id
By default, neither MIPs nor the
rules for generating MIPs are
configured.
Configuring CFD functions
Configuration prerequisites
Complete basic CFD settings.
Configuring CC on MEPs
CAUTION:
•
You must configure the same interval field value in CCM messages sent by the MEPs belonging to the
same MA.
You must configure CC before configuring other CFD functions. After the CC function is configured, MEPs
can send CCM frames to one another to check the connectivity between them.
If the switch has two MPUs, the CCM frames will be sent by the active MPU. If the active MPU is removed,
the standby MPU will take over to send CCM frames and CC will be re-performed.
Table 9 Relationship between the interval field value in the CCM messages, the interval between CCM
messages, and the timeout time of the remote MEP

NOTE:
The following describes CCM messages with the interval field value 2 to 3 as high-speed CCM messages,
and those with the interval field 4 to 7 as low-speed CCM messages.
