How to show C4900M SFP optical power level?

Hi there,

I have an C4900M with twingig converter and SFP GLC-LX-SMD in. So the SFP supports DOM function. It is running on 12.2(53)SG2.

I would to the see the optical power level of the SFP, but it does not recognize 'show interface transceiver' command as showed in 4500 software guide. Any one know what else command to check the power level?

Thanks,

The command is not accepted by 4900M.

Check if the transceiver monitoring is enabled. The command to enable it is "transceiver type all".

And if it still does not work, try with 12.2(54)SG as 12.2(53)SG3 had changes in DOM support.
