MEP and MIP Support 
The following is a general table that indicates the ETH-CFM support for the different services and 
endpoints. It is not meant to indicate the services that are supported or the requirements for those 
services on the individual platforms.
Table 6: ETH-CFM Support Matrix
Note: Ethernet-Rings are not configurable under all service types. Any service restrictions for 
MEP direction or MIP support will override the generic capability of the Ethernet-Ring MPs. For 
more information on Ethernet-Rings, refer to the 7210 SAS M, X Interfaces Guide.
Note: An Ingress MIP or a Down MIP refers to an unidirectional MIP. In 7210, MIP is uni-
directional in that only CFM OAM packets received in the ingress direction is processed.
Note: Routed VPLS Service is supported only in 7210 SAS-M access-uplink mode. It is not 
supported in 7210 SAS-M network mode.
