Chapter 10: Carrier Ethernet Local Management Interface
Ethernet local management interface (ELMI) protocol defined in Reference 1 operates between the customer edge (CE) device and network edge (NE) of service provider. It defines the protocol and procedures allowing autoconfiguration of the CE (customer equipment) device by the service provider's NE device (Fig. 10.1). The ELMI protocol also provides the means of notification of the status of an EVC and UNI, and enables the CE to request and receive status and service attributes information  from the MEN, so that it can configure itself to access Metro Ethernet services.
ELMI is a protocol that is terminated by the UNI-C on the CE side of the UNI and by the UNI-N on the MEN side of the UNI (Fig. 10.2).
The ELMI protocol includes the following procedures:
