I have used the engineers tool kit for a while, and today noticed something odd.
When I used the switchport mapper, it only shows the mac addresses of devices on the uplink/trunk ports. None of the mac addresses for the actual access ports are shown. I have made sure the SNMP community I use is correct, as well as the gateway.
Anything obvious i am missing?
Did you define both the Switch/Hub and the Router/Server field before mapping the ports? Typically, what I've found, is that missing one of these before the mapping will result in what you wrote.
