14-4 config cfm ma
Description
This command is used to configure the parameters of a maintenance association. The MEP list
specified for an MA can be located in different devices. MEPs must be created on the ports of these
devices explicitly. An MEP will transmit a CCM packet periodically across the MA. The receiving MEP
will verify these received CCM packets from the other MEPs against this MEP list for the configuration
integrity check.
