Switching Lab Emulation With Packet Tracer

Packet Tracer is a routing and switching simulator distributed by Cisco free of charge. It is capable of emulating reasonably complex routing and switching scenarios and is perfect for students studying for their CCNA. Although it does not offer all the BGP commands for the CCNP as GNS3 or Dynamips It has one extremely valuable feature over these applications, it supports level 2 and 3 switching simulation with devices like the 2950 and 3560 as well as generic device that permits the user to create devices with other interfaces such as the NM-1FFE and NM-1FGE. It supports a fairly broad range of commands allowing the user to create extremely advanced switching scenarios. I myself have completed several switching lab with Ether Channel, VTP, MLS, and more. While you cannot implement some features like HSRP, Packet Tracer is by far the best switch emulator available outside of purchasing actual hardware. Additionally you do not have to acquire Cisco IOS's in order to use Packet Tracer.
Packet Tracer can also be used for the CCNA Voice and Wireless Practice labs as it also includes the Cisco 7960 IP phone and wireless routing devices.
The current version of Packet Tracer is 5.3.1 and can be found on a number of websites for the Windows and Linux GNU platforms. It requires the following system requirements:

• Microsoft Windows 2000, XP, Vista, 7 or Ubuntu 7.10, Fedora 7.


• Intel Pentium 300 MHz or better.


• 96 Mb. of ram or better.


• 250 Mb. of storage or better.


• 800X600 monitor or better.
