Remote SNMP

SNMP (Simple Network Management Protocol) is widely supported by routers, switches, printers, UPS devices and many other network equipment. Choose Options → Remote SNMP from the menu.

The dialog shows four columns: Item Name, Community/User, Version and MIB OID. When creating a new entry, select the SNMP version:

• Windows built-in — uses the operating system’s SNMP implementation.
• SNMPv1, SNMPv2c — community-based authentication. Enter one or more community strings separated by commas.
• SNMPv3 — secure authentication with username, auth password and privacy password.

The string display mode can be set to Automatic detection, ASCII or HEX.

There is a built-in MIB browser for easy selection of OIDs. The browser shows the standard MIB tree and a symbolic path for the selected OID. You can add custom MIB files to %APPDATA%\SoftPerfect Network Scanner\MIBs.

OIDs may contain the variable parts %0 and %1. The former is replaced with the octets of the scanned IP address, and the latter with the octets of the scanned MAC address. For example, the OID 1.3.6.1.2.1.4.20.1.3.%0 can be used to extract a device’s network mask.
