Solarwinds NMS verifies the SNMP write configuration of its nodes (agents) by attemping to set the ‘sysContact.0’ (1.3.6.1.2.1.1.4.0) value.

On Net-SNMP you must first configure the ‘rwcommunity’ setting in the snmpd.conf file. Do not set ‘sysContact’ value in snmpd.conf.

Configuring ‘sysContact’ (or any other ‘sys’ setting) in the configuration file, results in that value being set as read-only. You will not be able to remotely configure the value, and Solarwinds configuration tests will fail.

Instead set values like ‘sysContact’, ‘sysName’, ‘sysDecr’ etc, using the command snmpset included with net-snmp.
