Chapter 1: Introduction
Overview
The Gigabit Ethernet Switch is an intelligent multilayer switch (Layer 2, 3) with 20
10/100/1000BASE-T ports and four 10/100/1000BASE-T combination ports
*
that are
shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24). The rear panel
provides two slots for single-port 10 Gigabit Ethernet hot-swappable expansion
modules, and two stacking ports. Units can be stacked up to eight high through the
built-in stacking ports that provide a 48 Gbps stack backplane.
The switch includes an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access for managing the stack.
The switch can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly
performing networks by segregating them into separate broadcast domains with
IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast
switching and CoS services, and eliminates conventional router bottlenecks.
The switch can be used to augment or completely replace slow legacy routers,
off-loading local IP traffic to release valuable resources for non-IP routing or WAN
access. With wire-speed performance for Layer 2 and Layer 3, the switch can
significantly improve the throughput between IP segments or VLANs.

on GTL-2691.
