Configuring MIP generation rules
As functional entities in a service instance, MIPs respond to various CFD frames, such as LTM frames, LBM
frames, 1DM frames, DMM frames, and TST frames. You can choose appropriate MIP generation rules
based on your network design.
To configure the rules for generating MIPs:

Command Remarks
1. Enter system view.
system-view N/A
2. Configure the rules
for generating MIPs.
cfd mip-rule { default | explicit }
service-instance instance-id
By default, neither MIPs nor the rules for
generating MIPs are configured.
Any of the following actions or cases can cause MIPs to be created or deleted after you have configured
the cfd mip-rule command:
• Enabling CFD (use the cfd enable command).
• Creating or deleting the MEPs on a port.
• Changes occur to the VLAN attribute of a port.
• The rule specified in the cfd mip-rule command changes.
Configuring CFD functions
Configuration prerequisites
Complete basic CFD settings.
Configuring CC on MEPs
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.
