Hi

 

I’m having trouble with sensors on SFPs in Aruba switches. Looking at the switch, I get this:

 

Transceiver in 3/49

   Interface Index    : 155

   Type               : SFP+LR         

   Model              : J9151A 

   Connector Type     : LC                             

   Wavelength         : 1310nm                         

   Transfer Distance  : 10.0km (9um),                                  

   Diagnostic Support : DOM  

   Serial Number      : AX07SL0130407  

 

Status

   Temperature : 26.289C        

   Voltage     : 3.3408V        

   Tx Bias     : 41.728mA       

   Tx Power    : 0.6339mW, -1.980dBm    

   Rx Power    : 0.4225mW, -3.742dBm

 

But looking in Observium, I get this:

 


There’s no data for RX power (which is the most interesting) and the data for TX power is wrong.

 

I think this is an OEM SFP (the serial number looks weird), but if the switch can see the data, shouldn’t Observium be able to pull it too?

 

Temperature, voltage and current graphs are correct.

 

… and just now, when I clicked around, the correct values are now showing for TX and RX power in the graphs. What’s going on?
