An interface point might have a status of Bad Input if the host specified in the point’s instrumenttag attribute is incorrect, or if the KEY value specified in the extended descriptor does not match the one received from the network device. For example, for a point with the following options specified in its extended descriptor attribute:

KEY=Serial1/0.1; OID_I=ifInOctets.25

the value received from the network device for

interfaces.ifTable.ifEntry.ifDescr.25

is not Serial1/0.1. The most likely cause of this problem is that, after a reboot, the network device reassigned index numbers to its interfaces. Edit the PI points so that they contain the correct index numbers.
