Hi,

I am trying to get power levels i am receiving on my transceiver but when i input command “#show interfaces transceiver” it only gives the transceivers details.

How can i check how much power i am recieving.

Thanks

Hi @Kumbu14

When you run the command “#show interfaces transceiver” it should give you an output similar to the below one:

In this output, you can see the RX and TX power for the SFP plugged in. Can you please elaborate on what exact details you are looking for?

Hi @Kumbu14  
It looks to me like this vendor’s SFP will not provide power information.  
In my example, a Cambium SFP used, which displays the power information.  
We have another vendor’s SFP in our lab that doesn’t provide the power information. See below:

Hi @Kumbu14, what software version is installed on the switch? The SFP power information is available with software version 4.5 and later.
