Say, a network discovery shows a new IP address and we figured out its Mac address via NMAP. What is the easiest way to track it down to a switch port it is physically connected to?
- We do have SNMP monitoring of all of our switches via NPM 11. We don't have access to their dashboards with ARP tables as they're managed by another department. Is it possible to pull those ARP tables via SNMP? Can NPM do it?
- Don't have NTM.
- Not all of the physical interfaces on devices other than switches are monitored.
- We do not have a physical network topology diagram (which port connects to what device etc.)
So, is it possible to figure out what switch and what port a particular IP / MAC address combo is connected to, just via SNMP?
Longer term, we'd like to inventorize our devices down to every interface and MAC address, so we could track down new ones and always know what our IP addresses are.
What product(s) do we need for that?
Thanks!
