The 7210 SAS supports port-based MEPs for use with CFM ETH-BN. The port MEP must be configured at level 0 or 1 and can be used for ETH-BN message reception and processing as described in ITU-T Y.1731 Ethernet Bandwidth Notification. Port-based MEPs only support CFM CC, LT, LS, and RDI message processing; other CFM and Y.1731 messages are not supported.
Port-based MEPs are designed for the ETH-BN application. Nokia does not recommend the use of port-based MEPs with other applications.
