SNMP Versions

Using SNMP Version 1, 2c, and 3 in Probes

All SNMP-based probes can use one of version 1, 2c, or 3, at the user's choice. The Probe Configuration window allows you to specify the SNMP version at the same time you set all the other parameters for the probe.

The lower part of the Probe Configuration window displays the SNMP version information. Select the version from the SNMP Version menu.

  • Selecting SNMPv1 or SNMPv2c will show a field to enter the SNMP Read-only community string.

  • Selecting SNMPv3 changes the lower half of the probe configuration window to allow you to specify all authentication and privacy parameters. The initial settings show the default settings taken from the Server Settings > SNMP pane. For more information, see SNMP Preferences.


NOTE: Certain equipment requires SNMPv2 or SNMPv3, and probes can be built to force that selection. If you try to set the SNMP version lower than the probe can support, an error message is displayed.
