MEG Levels, MEGs, and MEPs (Y.1731)
On the 7705 SAR, the implementation of Y.1731 Fault Management (FM) is similar to that
of dot1ag CFM, except that Y.1731 does not have a maintenance domain (MD). For Y.1731
and 802.1ag, the following terms are equivalent:
• MEG level is equivalent to MD level
• MEG is equivalent to MA
• a Y.1731 MEP is equivalent to a dot1ag MEP
To access Y.1731 functions, including Y.1731 Performance Management (PM) functions,
configure a MEP to have the domain format set to none and the association format set to icc-
based.
