Chapter 1: Introduction
Overview
The Gigabit Ethernet Switch is an intelligent multilayer switch (Layer 2 and 4) with
24 10/100/1000BASE-T ports, four of which are combination ports that are shared
with four SFP transceiver slots. There is also an SNMP-based management agent
embedded on the main board. This agent supports both in-band and out-of-band
access for managing the switch.
This switch provides a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. It brings
order to poorly performing networks by segregating them into separate broadcast
domains with IEEE 802.1Q compliant VLANs, and empowers multimedia
applications with multicast switching and CoS services.

Switch Architecture
The Gigabit Ethernet Switch employs a wire-speed, non-blocking switching fabric.
This permits simultaneous wire-speed transport of multiple packets at low latency on
all ports. This switch also features full-duplex capability on all ports, which effectively
doubles the bandwidth of each connection.
The switch uses store-and-forward switching to ensure maximum data integrity. With
store-and-forward switching, the entire packet must be received into a buffer and
checked for validity before being forwarded. This prevents errors from being
propagated throughout the network.
Network Management Options
This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of
network and port status. It also includes a management agent that allows you to
configure or monitor the switch using its embedded management software, or via
SNMP applications. To manage the switch, you can make a direct connection to the
RS-232 console port (out-of-band), or you can manage the switch through a network
