I gave this presentation 3 times, regarding the demo the first time I used CISCO
packet tracer (simulator) by configuring the router with the SNMP configuration and
adding a community-string then browsing the router elements via an MIB browser from

the second and third times I made a live demo by using the (pure PERL SNMP library)
and writing a small PERL script using the functions from it and connected my laptop
to the configured router using putty..
