I'm assuming the tx/rx values are collected as part of the sensors collection (at least on Cisco, TX/RX of SFP's are usually reported as sensors whose values can be read).

It might help if you set 'nav.ipdevpoll.plugins.statsensors = DEBUG' in `logging.conf`. This should debug log the raw values NAV reads from the device. There might be something wrong that happens when converting the number to the given precision of the sensor.
