Title: ifOperStatus value

Hi

  How  ifOperStatus value in ifTable get populated for different intefaces?

  I have wireless interface configured on the device, When i am sending get on  ifOperStatus.3 it is showing up but if i send ifTable get using "snmptable" it is showing down for that particular interface.

  Even though wireless interface is working fine and it is sending/receiving data for long time, ifOperStatus.3   
is having value down sometimes.

  How to make this status to reflect actual status of my wireless interface?

Regards
Kanda
