The catch is you have no SNMP access, not even public.
The end vision is locate a PC in building easily even if PC's are moved around.
The MAC address of the PC is known and the software would run as client on each desktop, reporting back which port the PC was plugged into.
Well from a programmer perspective, my network skills are not the best. Yes I could use SNMP, download the MAC port table, load it into SQL, match it to the PC name. Seems alot of work.
Lets say I ping a single point from the PC. Would the echo have some thing unique for each device on the same switch? All I need to identify some thing unique for each PC plugged into each port.
If the PC was moved from location A to a different location then the unique response would change.
