Ethernet Private LAN (EPLAN) is a Metro Ethernet service type defined by the Metro Ethernet Forum. It describes any E-LAN Metro Ethernet service that does not permit service multiplexing at the Ethernet user-to-network interface (UNI).

Because E-LAN services implement multipoint-to-multipoint Ethernet virtual connections (EVC), multiple locations can be interconnected using an EPLAN service. However, each location can be a member of one and only one EVC. If a given location requires connection to a second EVC, it will require a second UNI.

Because there is only one EVC per UNI, the EVC can be invisible to the customer (e.g., the customer will not see an 802.1p VLAN tag).
