<div>Hi,</div>
<div> </div>
<div>I am observing differnet poll values for POS 0/0/0/0 and POS 0/1/0/0 while monitoring optical power (DOM). The output shows following tx/rx power<br clear="all">
</div>
<div></div>
<div>1). Tx power = 0.4930 mW, -3.1 dBm</div>
<div> </div>
<div>2). Tx power = 0.5400 mW, -2.7 dBm</div>
<div> </div>
<div>The polled values are:</div>
<div> </div>
<div>For 1), </div>

1240389600 45 45 45 45</div>
<div> </div>
<div>Plz suggest if there is something wrong in the cfg as both the interfaces are using same OID on the same router.</div>
