When attempting to to query the host in the profile setup, error window pops up with "No SNMP Response" "Unable to get any SNMP information from ...."
It may be that the service name definition for snmp has been changed.
Make sure that the community string and IP address are correct.
On the robot running interface_traffic, check that the snmp entry in c:/WINNT/system32/drivers/etc/SERVICES. It should look like this:
snmp 161/udp #SNMP
If the value is other than 161 (often it has been changed to 50161), then reset the entry to 161, save the changes, and restart the interface_traffic probe.
(Please note that the path to etc/SERVICES may be different than shown above depending on the version of Windows.)
