SFP output power high warning

[Luca]

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?

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

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.

Mine have calmed down a bit lately. They used to be constant, now only get a few a day Running 11.4r1.9

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.
