SFP output power high warning

I'm getting these constantly in on my EX4500 VC.

 

is it an issue?  I thought these happened when you had miss-matched SFPs but all mine are Juniper ones.  Also how can i identify thet interface this is happening on?

Re: SFP output power high warning

Hi Luca,

 

I don't think there is an easy way to match up the link number to an interface, but if you run:

 

show interfaces diagnostics optics <interface-name>

 

on each of your interfaces you will see a "Yes" next to the TX Power High Threshold row.

 

I'm not sure what conditions would cause this error - but it may be a faulty optic that is out of spec?

 

Hope this helps

Re: SFP output power high warning

I started getting these as well.

 

EX4200, all Juniper SFP's, all SFP's in use.

 

Upgraded from 10.4 to 11.4.

 

Must be a bug in the code.

Re: SFP output power high warning

In case the inteface has no any connectivity (no fiber connected,etc), you needn't worry about this.

Juniper consider there has h/w failure only while you see same logs when normal running status.

 

Even it was different, please check below KB for reference. as it could I2C mistaken reading.
