The Get SNMP Variable activity will query a network device for the value of variable that is assigned to the Management Information Base address that you specify. You can use the Get SNMP Variable activity to retrieve information about a network device to determine if an administrator needs to be notified.

Before you configure the Get SNMP Variable activity, you need to determine the following:

  • The IP address of the device, as well as the port number, SNMP MIB, and SNMP version

  • The community string required to retrieve the variable.
