The Get Community is a read-only password that SNMP agents installed on managed devices use for authentication. The Get Community allows OpenManage Essentials to browse and retrieve SNMP data. This field is case-sensitive. OpenManage Essentials uses the first successful community name to communicate with the device. You can enter multiple SNMP community strings separated with commas. For more information, see Configuring SNMP Services on Windows.

Set community

The Set community allows OpenManage Essentials to perform tasks that require the SNMP protocol, such as shutting down a system.

This field is case-sensitive. You can enter multiple SNMP community strings separated with commas. OpenManage Essentials uses the first successful community name to communicate with the device.

  • NOTE: In addition to the Set community name, an instrumentation password is required to perform an SNMP task on a device.
