Hello softperfect, I have an issue with Netscan I cant make work the SNMP function on my switches. I can browse MIB from my switches with other tools such snmpwalk but it cannot work with netscan, any clue why it wouldnt work? I've captured packets and saw there is not snmp request on those switches, also another issue netscan cant detect the open port tcp 80 on those switches, i dont understand why.
What could prevent the software to not make an UDP request to port 161 snmp? Its working well with a windows server with snmp enabled. It working on those switch with another snmp view tool. SNMP community is public.

example is 1.3.6.1.2.1.1.1.0, you can see a sample done with another snmp client attached.
zip pass is the name of the protocol.
EDIT:
I checked again, and there is no snmp request at all made by netscan, which test netscan is doing before trying to do snmp request?
Maybe i found something, the switch has no dns resolve for its private ip adress, do you test this before querying open ports and snmp walk?

This is quite weird as netscan does not need a DNS name to send out SNMP requests, an IP address is sufficient.
I hope you could publish here some screen shots of what you are getting and also do try the built-in SNMP version.
In that case a different implementation is used (SNMP features available in Windows) and let's see if that works.
My suspicion though is a firewall installed on your computer that runs netscan.
