Abstract:
An Ethernet local management interface (E-LMI) protocol for use at a user-to-network interface (UNI) of a Metro Ethernet Network (MEN) is disclosed. The E-LMI protocol allows configuration and status information for the services at the UNI to be transferred from the MEN to a customer edge device coupled to the MEN at the UNI. Various embodiments involve sending or receiving a message via a User-to-Network Interface (UNI) of a Metro Ethernet Network (MEN). A customer edge device extracts configuration and status information for the services at the UNI from a received message. The configuration and status information can correspond to a multipoint Ethernet Virtual Connection (EVC).
