[j-nsp] EX4550 and 3rd Party SFP-1GE-LX

[Joe Wooller]

Hey All, 

I was wondering if anyone out there has seen issues with 3rd party 1Gig LX Optics on the EX4550.
We have a bunch of 3rd party optics working fine in EX2200s, 3200s and 4200s however when I stick them into the EX4550 it randomly likes to fail (I can't seem to figure out the pattern). Sometimes it will work and sometimes it wont.
When it does fail however it seems to make the port inoperable until the switch is rebooted. (It also appears to make other ports break too, perhaps they are on the same PFE?). Even inserting a Genuine optic after the port has failed produces the same error.
Without further ado here is the error it produces;

I would be interested to see if anyone else has encountered this?
So far I can not replicate the issue with 3rd party Copper SPF;s or 10Gig SFP+'s.

Cheers
