Within a given domain, you can associate maintenance associations (MAs). Extreme Networks‘ implementation of CFM associates MAs with service instances. All of the ports in that service instance are now in that MA and its associated domain.
Each MA associates with one service instance, and each service instance may associate with more than one MA; you can configure more than one MAs in any one domain.

In addition to supporting multicast destination MAC address for CCM and LTM frames specified by the 802.1ag standard, ExtremeXOS CFM supports the use of a unicast destination address for CCM and LTM frames.
This allows the support of a CFM operation in a network where use of multicast address is prohibited.
ExtremeXOS CFM supports configuring remote MEPs statically for CFM operation where dynamic discovery of MEPs in an MA using multicast address is prohibited.
