I’m just playing/starting to see what The Dude can do, and it would seem the answer is “rather a lot”!
We have three core switches, into which all our edge switches aggregate. The edge switches are typically dumb, and a total mix of brands/models.
If I add the core switches to a network map and look at the snmp tab, I can see various arp and bridge fdb details.
What I appear to be seeing is basically a list of what MAC addresses are visible off each port of the switch.
This would make sense in that if I know I have a switch hanging off port B3, I know anything visible off port B3 is connected to that switch.
What I’m not clear on is this - the arp and bridge fdb columns seems to show MAC addresses and IP addresses, but don’t show IP resolution and I don’t understand why the column/option doesn’t even appear to be there given that we have a working DNS so whilst not everything would resolve, things such as servers, workstations, and network printers certainly would.
Am I missing an obvious option?
I also don’t seem to have any links drawn between switches - perhaps I’m being overly optimistic but I’d have thought that if The Dude can see that Netgear Switch XYZ is visible off Port C7 on the core switch, it would draw in the link?
