I just want to clarify the issue, the bandwidth was working for a while and then stopped only for the devices that are configures for SNMP version 3?
Make sure that the Network Switch / Router wizard if up to date by going in to the Admin > Manage Config Wizards menu and clicking on the Check for updates button to download a new list.
Then scroll down and update the wizard to the latest.
Also, can you post your /etc/mrtg/mrtg.cfg file so we can view it?
If you run the following command as root, you can view the errors in the /tmp/mrtg.txt file to troubleshoot this better.

Please help me, why I am getting this error output.
If the device at IP address 10.10.10.1 still active? The messages suggest that the device is not active anymore.
It it is, make sure that it is setup to be polled using SNMP version 2 and that the community string is set to dpix.
If the device is not active, the config file for that device has to be removed so MRTG will not try and poll it anymore.
The config file is usually in this location on the server.
If those devices have SNMP enabled to poll the network interfaces, you can see if the Network Switch / Router wizard will work for monitoring them.
If the wizard can be used for other devices besides switches and routers.
Try running that and see if they work for you.
Be sure to check out our Knowledgebase for helpful articles and solutions!
As suggest added ISILON device in Switch/Router wizard, device added but showing ports status as WARNING: SNMP error: No response from remote host "10.111.100.160" for all the ports.
Here we have individual IP for each port.
Showing bandwidth graph with value zero 0 IN/OUT.
Please find the attached screen shots.
Thanks
You do not have the required permissions to view the files attached to this post.
The no response error is caused by either the remote device does not have SNMP enabled or that the community string is incorrect.
If you run the following command from the Nagios server, it will tell you that the SNMP port is open on that device.
