IP listing per switch port
On Cisco core switch 3850, I need to get a list of end devices IP address and it associated port on the switch
You can do a sweep from nmap to survey active I addresses.
Within each LAN you can monitor the answers obtained and associate with MAC addresses.
On a switch you can at the same time look at the MAC/CAM table to find the associations between ports & mac addresses.

A possible shortcut is DHCP snooping, if it can be applied and if all hosts use DHCP.
