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

[Joe Wooller]

Thanks, 

When you put a dud SFP in it only impacts a handful of ports at a time, depending on which port you stuck it in first.
I haven't sat down and mapped out which ports are impacted etc, I may do that tonight to see if I can map it out.
Also it only happens sometimes. The optic doesn't always cause an issue the first time, but after rebooting/swapping the sfp in and out, it can cause the issue.
