Configuring ELMI

Figure 20-4 shows an example of ELMI that is configured in a multipoint EVC network.

These guidelines apply to Figure 20-4:

In a MEN, the EVC status is determined by the OAM protocol. In the Catalyst operating system,

ELMI relies on CFM to provide an end-to-end status of the EVC across CFM domains (PE device)

in MEN and updates the CE device through ELMI.

The Catalyst operating system supports ELMI only in the PE mode.

User Network Interface (UNI)—UNI is the physical demarcation point between the service provider

and the customer. Its attributes, which are similar to the UNI identifier and UNI type, are defined on

the PE port that connects to the CE device. The ELMI protocol runs on the UNI interface.

Notifies the CE when an EVC is added.

Notifies the CE when an EVC is deleted.

Notifies the CE of the availability of a configured EVC (Active, Not Active, or Partially Active).

Communicates UNI and EVC attributes to the CE.
