Chapter 12: Initial Switch Conﬁguration

he 2940, 2955, and 2960 series of switches are Cisco's current desktop and workgroup

switching solution; they replace the 1900 and 2950 switches.The new switches support

Fast Ethernet and Gigabit Ethernet interfaces.This book, and the CCNA exam, focus

on the end-of-sale 2950 and the newer 2960 switches, but the topics and configuration commands

discussed in this chapter apply to all of Cisco's Catalyst switches running the Internetwork

Operating System (IOS).

CERTIFICATION OBJECTIVE 12.01

2960 Overview

The 2960 series of switches comes with the LAN-based software image, which

provides advanced quality of service, rate limiting, access control list (ACL), and

many other features. Table 12-1 compares the 2960 switches and their port types and

capacities. The dual-purpose Gigabit Ethernet (GE) port supports a 10/100/1000

port and an SFP (fiber) port, where one of the two ports (not both) can be used. If a

2960 supports dual-ports, this is displayed in the Dual-Purpose column of Table 12-1.

The 2960 series supports an optional external redundant power supply (RPS) that

can be attached to the rear of the chassis.
