In order to troubleshoot few MAC addresses displayed I need to see what your switch actually exposes.
Please download the Net-SNMP package
here.
Then locate 'snmpwalk' and launch it as
snmpwalk -v 1 -c communityname x.x.x.x > sometextfile.txt
Where x.x.x.x is the IP address of the switch and then email me the output file to support
at softperfect.com.
As to IP addresses, the software needs SNMP access to a router. This is what the Port Mapper does:
- Obtains a list of ports and MAC addresses connected to those ports from a switch.
- Obtains a list of MAC-to-IP address mappings from a router.
- Cross-references the data received from the switch and the router and produces a final report.
Some advanced switches are both a switch and a router in one device. In that case you can enter the same address again as the router's address and it will display IP information.
If however the above doesn't work, you need to find a way to pull SNMP data from your router to see IP information.
