SNMP Scanner

NetCrunch Admin Toolset

Query SNMP devices and verify configurations

SNMP Scanner helps you quickly discover and query SNMP-enabled devices across any IP range.

It supports SNMP v1, v2c, and v3, making it the perfect utility for verifying device configuration and connectivity without requiring a complete network management system.

The tool retrieves core identification data from each SNMP node, including:

  • sysObjectID — used to classify the device type
  • sysDescr — describing the OS, firmware, or system version
  • sysLocation — physical or logical location
  • sysUpTime — how long the device has been running

You can use it to scan an entire subnet or a specific address. This is especially useful for testing SNMP settings like community strings or credentials for SNMPv3 (authentication and privacy options supported).

The scanner shows live response times, device descriptions, and SNMP version compatibility, making it ideal for device inventory, SNMP setup validation, and basic network audits.

This scanner provides fast insight without installing anything complex, whether you’re deploying monitoring, replacing legacy SNMP agents, or troubleshooting access issues.
