Or if you're poor and can't afford a management suite, you can display the ARP table on the switch to figure out what's 
plugged in where, or if they're "nice" switches, they have a sticky learning capability that will lock whatever is on 
the port at the time in and not let other mac addresses connected.

Depending on the switches, you could lock ports to mac addresses. A
management suite such as pinnacle would likely ease the
implementation.

I am coming into an environment of over 1000 clients everything is setup

devices for that matter so just wondering how everyone else is securing
