Re: UNI and NNI

*Q.* What is UNI/NNI?
*A.* UNI/NNI is the classification of port types designed for the Metro
Ethernet market. UNI, User Network Interface, is the interface that faces
the subscriber, and NNI, Network Node Interface, is the interface that
faces the service provider network. By labeling each port as UNI or NNI,
the software can optimize each port for its role. Table 2 lists some
default behaviors for each port type and the benefits.
