Chapter 2: New in this release

The following sections detail what is new in Network Design Reference for Avaya Virtual Services

Platform 4000 Series, NN46251-200.

VOSS 4.2.1

Features

See the following sections for information about feature-related changes.

Loop prevention and detection

For VOSS 4.2.1, references to Loop Detect have been removed from the section

Loop prevention

and detection on page 43. Avaya Virtual Services Platform 4000 Series uses Simple Loop

Prevention Protocol (SLPP) as the solution to detect loops.
