Defining CFM Structures

Also note that while MEPs are active agents which can initiate
consistency check messages (CCMs), transmit loop back or link trace
messages, and maintain the local CCM database. MIPs, on the other
hand are passive agents which can only validate received CFM
messages, and respond to loop back and link trace messages.
The MIP creation method defined by the
ma index name command
takes precedence over the method defined by this command.

This example creates a maintenance domain set to maintenance level 3,
and enters CFM configuration mode for this domain.

◆
To avoid generating an excessive number of traps, the complete CFM
maintenance structure and process parameters should be configured
prior to globally enabling CFM processing with this command.
Specifically, the maintenance domains, maintenance associations, and
MEPs should be configured on each participating bridge.
◆
When CFM is enabled, hardware resources are allocated for CFM
processing.
