Freeware tools and useful
These are the latest tools for
download. Theyíre all freeware and can be used without fear of retribution!
In most cases (when possible), Iíve included the link to the
developer/distributor website to ensure that you download the latest version
and get the most current support information. Hope these help.
Also...If you come across a bad link or have something to add/update, please
take a moment and send me a quick email.

9300 routing switch
About: This emulator approximates
the operation of a 9300-series routing switch and, therefore, should be used
only as a study tool.
It defaults to the Foundry product name but itís the same as the firmware for
HP. The emulator is for an early version of the 07.x firmware; so, it
may not be exactly like the most current version of firmware. And, like most
emulators, it does not allow every available command...but it does a
very good job.
Important note: If you find that the emulator differs from the
courseware, then always follow the courseware...because it provides the
information that is fair-game on the exam.

RADIUS server setup
About: Written by Jimmy Ray Purser, an HP SA out of Chicago. This document contains
step-by-step instructions for configuring a RADIUS server and a switch to
support 802.1x authentication. Itís the first REALLY useful paper Iíve
come across on the subject. If you have not configured this before, you
should try it out on a non-production server. By the way, if you have any
related information on 802.1x, PLEASE email it to me so that I can include it

Time Services. Optionally, you can disable these services within

(unicast, multicast and broadcast)generator for testing.

MCAST multicast traffic
About: Use this
multicast traffic reciever with TFGEN. Set TFGEN to send to a mutlicast
address, i.e., 184.108.40.206 and a vaild port, i.e., 5000. Set Mcast to receive
that traffic. A packet-capture will show the IGMP Joins and Leaves.

Packet capture tools
About: Once Ethereal;
now Wireshark. This is an open source network protocol analyzer for most
platforms. It allows you to examine data from a live network or from a
capture file on disk. You can interactively browse the capture data, viewing
summary and detail information for each packet. Wireshark has several
powerful features, including a rich display filter language and the
ability to view the reconstructed stream of a TCP session.
