You can't poll negative values. Maybe someone can offer an alternative, but MRTG itself cannot handle a negative polling value.

The output shows following tx/rx power 1). Tx power = 0.4930 mW, -3.1 dBm 2). Tx power = 0.5400 mW, -2.7 dBm The polled values are: For 1), 1240390321 2538 2538 1240390321 2538 2538 2538 2538 1240390019 2538 2538 2538 2538 1240389900 2538 2538 2538 2538 1240389600 2538 2538 2538 2538 For 2), 1240390321 45 45 1240390321 45 45 45 45 1240390019 45 45 45 45 1240389900 45 45 45 45 1240389600 45 45 45 45 Plz suggest if there is something wrong in the cfg as both the interfaces are using same OID on the same router.
