•
MEP (MEG End Points) – Each MEP is located on a service point of an Ethernet service at the boundary of the
MEG. By exchanging CCMs (Continuity Check Messages), local and remote MEPs have the ability to detect the
network status, discover the MAC address of the remote unit/port where the peer MEP is defined, and
identify network failures.
•
MIP –(MEG Intermediate Points) – Similar to MEPs, but located inside the MEG and can only respond to, not
initiate, CCM messages.
•
CCM (Continuity Check Message) – MEPs in the network exchange CCMs with their peers at defined intervals.
This enables each MEP to detect loss of connectivity or failure in the remote MEP.
