Enterasys Networks Fast Network 10 manual 3 FN10 Filtering, 4 FN10 Sample Applications

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 stores up to 200 static or user-defined addresses.

1.5.3 FN10 Filtering

One of the most significant features of the FN10 is its user-configurable filtering capabilities. A filter is an instruction to the FN10 to screen data packets based on the criteria you define. Filtering is useful for gathering statistics, implementing security measures, and improving network performance.

The FN10 allows you to implement two types of filters that are useful for managing and administering networks:

•Bridge Address Table filters, which use the FN10 Bridge Address Table to screen local traffic

•Port filters, which apply filters to or from a specific port segment See Chapter 5, FN10 Filters for instructions on setting up FN10 filters.

1.5.4 FN10 Sample Applications

Just as a six lane highway allows you to travel much faster than a single lane highway, a network backbone creates high-speed connections for your network. In general, a network backbone allows you to distribute access to important network resources such as file or print servers.
