[j-nsp] LX SFP Question

[Mike Mainer]

on M&T routers you always have the command list below to give you light 
rx/tx levels/thresholds but Juniper removed this command from the EX 
version of JUNOS.  They actually had the command in early releases (9.2) 
but it did not provide any output.  I know in 9.4r3.5 Juniper just 
removed that command altogether.  We had asked our SE to have this added 
as a "feature request" but nothing so far...
