The 7210 SAS supports port-based MEPs for use with CFM ETH-BN. The port MEP must be configured at level 0 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. No other CFM and Y.1731 messages are supported on these port-based MEPs.
Port-based MEPs are designed to be used with the ETH-BN application. Nokia recommends not to use port-based MEPs for other applications.
