I cannot get our d-link DGS-3100-48 switch to work with PRTG is there something specific I need to do or is this switch just not able to be monitored?

We monitor several DGS-3100 routers using SNMP and PRTG. Be sure that the firewall is off on the monitoring PC and anything in the path between PRTG and the 3100. The standard "SNMP Traffic" sensor should show you all of the ports, etc. If you get the MIBs from D-Link you can find quite a bit more.

Also in the DGS-3100 menu under Configuration -> SNMP Settings

  1. Add Group Name of public
  2. Add Community Table name of public
  3. Add Host Table with the IP address of the querying PRTG PC (10.10.X.X or whatever) and specify public
  4. Ensure that an Engine ID has been defined (choose automatic)
  5. Ensure that SNMP is enabled.

That should do it. Good Luck!

Dear Sarah,

This depends whether the physical device supports monitoring protocols that PRTG supports. Most common are SNMP, Netflow or WMI. PRTG is also able to monitor various types of servers (Webserver, FTP, DNS, SQL etc), but for actual hardware it would be necessary for the device to support one of the three mentioned "protocols" to be monitored by PRTG. You can test all three ways with one of our freeware networking tools (https://www.paessler.com/tools): SNMP Tester, WMI Tester and the Netflow Tester.

Best Regards.

the switch does (apparently) support SNMP, I just dont seem to be able to get the switch and PRTG to 'talk', do you have any instructions specifically for the d-link switch?

We don't have a specific guide for this switch. As said, simple tests can be done with the SNMP Tester (i.e. it should at least be possible to read the SNMP Uptime with the tester from the switch), if the connection is properly configured. But it may also be that this switch only uses SNMP for configuration purposes and not for monitoring (the product page is not really clear about that: "And easy-to-use administration interfaces, along with SNMP and RMON, mean faster setup and configuration with less downtime." http://www.dlink.com/products/?pid=637 )

Thanks for the replies. I have managed to get the D-link DGS-3100 to send information to our PRTG server, however, it is just reporting 'No Such Name (SNMP error # 2) against each interface.
