Avaya P330 Layer 2 Features
This section describes the Avaya P330 Layer 2 features. It provides the basic 
procedures for configuring the P330 for Layer 2 operation.
Overview
The P330 family supports a range of  Layer 2 features. Each feature has CLI 
commands associated with it. These commands are used to configure, operate, or 
monitor switch activity for each of the Layer 2 features.
This section of the User’s Guide explains each of the features. Specifically, the topics 
discussed here include:
Ethernet
VLAN
Port Based Network Access Control
Spanning Tree Protocol
Rapid Spanning Tree Protocol
MAC  Security
Link Aggregation Group (LAG)
Port  Redundancy
IP Multicast Filtering 
Stack Health
Stack Redundancy
Port Classification
Ethernet
Ethernet is one of the most widely implemented LAN standards. It uses the Carrier 
Sense Multiple Access with Collision Detection (CSMA/CD) access method to 
handle simultaneous demands. CSMA/CD is a multi-user network allocation 
procedure in which every station can receive the transmissions of every other 
station. Each station waits for the network to be idle before transmitting and each 
station can detect collisions by other stations.
The first version of Ethernet supported data transfer rates of 10 Mbps, and is 
therefore known as 10BASE-T.
