EVC Control List Configuration

This section displays current EVC configurations. On this system, only Provider Bridge based EVCs
are supported.
An Ethernet virtual connection (EVC) is a logical relationship between Ethernet user-to-network
interfaces (UNI) in a provider Ethernet service.
When such service provider offers a Metro Ethernet service that is compliant with the Metro Ethernet
Forum (MEF) specifications, the service has two basic elements: the UNI by which the service is
provided to the customer, and an EVC that establishes a communication relationship between one
or more UNIs.
In Metro Ethernet services, there are three types of EVC:
Point-to-point: an EVC that supports communication between two (and only two) UNIs. This type
of EVC operates similarly to a virtual circuit. It is service type known as Eline
(Ethernet Line Service )
Multipoint-to-multipoint: an EVC that supports any-to-any communication between two or more
UNIs. This EVC creates a service that behaves like a switched Ethernet. It is a service type known as
E-LAN.(Ethernet Line Service)
Point-to-multipoint: an EVC that supports communication between two or more UNIs, but does
not support any-to-any communication. Specifically, UNIs are designated as root or leaf.
Transmissions from the root are delivered to the leaves, and transmission from the leaves is
delivered to the root(s). No communication can occur between the leaves or between the roots
It is a service type known as E-Tree
