<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Your device is not responding to the SNMP queries; this means a configuration error in either the device or in your Target line.<br>
<br>
Check your device is contactable by ping; that there is no SNMP ACL in place preventing you; that you have the correct community string; that the IP is correct.<br>
<br>
Try using snmpwalk to browse the OID from the commandline to test.<br>

<span style="font-size:12.8px">This is also assuming, of course, that the symbolic name tempSensorTemp can be expanded to an OID; for this to work, you need to have the MIB properly installed or referred to in the MRTG config file. Otherwise, you can always
