CHAPTER 1 INTRODUCTION 1.1 ABOUT THIS MANUAL This manual is for system administrators responsible for configuring, monitoring, and maintaining the Fast Network 10 (FN10). You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful. Some FN10 configurations can only be done using an SNMP-based Network Management System (NMS). Therefore, how you configure and manage the FN10 is dependent on the NMS you use. Where appli

Chapter 1: Introduction forwards the packet to the network segment associated with that destination address. However, if the packet’s source and destination address are on the same network segment, known as local traffic, the packet is automatically discarded (i.e., ignored by the FN10). For example, a file transmitted from Workstation A to Workstation C in Figure 1-4 does not need to leave LAN 1. The FN10 connected to LANs 1 and 2 sees all traffic from LAN 1, including LAN 1 local

Overview automatically reconfigured by the Spanning Tree protocol to create an alternate path to the LAN. 1.5.2 FN10 Bridge Address Table The FN10 creates and maintains a dynamic database of addresses called the Bridge Address Table. The FN10 examines every packet to determine its source address and LAN segment origin. It then compares the source address and segment information it finds to the entries in the Bridge Address Table. If a packet’s address is not already stored in the Bridge

Chapter 1: Introduction • A single port number of the LAN on which the address resides • The age of the entry • Various statistics counters • Any filtering restrictions added by a Network Management Station (NMS) Each static entry contains the same information as a dynamic entry, except the static entry is not aged, and can contain a range of port numbers, rather than a single port number. The FN10 stores 8,192 dynamic (learned) entries in its Bridge Address Table. In addition, it sto
