Introduction

Filtering Rate
The maximum number of packets that a switch
can receive and discard at the same time. The
maximum possible forwarding rate of any
switch is the speed of the ethernet (14880 pack-
ets per second) multiplied by the number of
ports.
Firewall
A method used to block all but a particular type
of traffic from reaching a network segment. Of-
ten used to limit traffic to packets originating
from specific nodes.
Flood
When the LSB4 receives a packet destined for a
specific address that is not in its address table,
it forwards the packet to all of its ports. This is
called flooding. All multicast packets (see page
iv) are automatically flooded.
Forwarding Rate
A measurement of the maximum rate at which
a switch can forward packets from one network
segment to another. Using ethernet, the maxi-
mum possible forwarding rate is 14880 packets
per second.
Learning State
When the Spanning Tree Algorithm is enabled,
the LSB4 can be in a number of different states.
During the Learning state, the LSB4 collects
hardware address information for its internal
address table.
Listening State
When the Spanning Tree Algorithm is enabled,
the LSB4 can be in a number of different states.
During the Listening state, an LSB4 ethernet
port will listen for BPDU packets from other
switches.
MACCON
A program that enables Macintosh users to
connect to the LSB4. To use MACCON, see Ap-
pendix E.
