Re: [AFMUG] Aviat WTM4200 Latency
What does the quarter hour and daily graphs look like? Modulation time, it should be 4096 90%++ what is the breakdown? Update to the latest release? Can you measure this another way?

turn auto neg off, try flow control on and off.

Re: [AFMUG] Aviat WTM4200 Latency
They're both brand new SFPs provided by Aviat. I guess if they have terrible quality control that could be the issue. That solution would make a lot more sense to me if it were just one end seeing the issues. I may have to at least attempt it if nothing else works, however.

I have not tried that as of yet. One end is a CCR1009, the other is a CCR2004. I could try Flow Control on one end to see if it makes a difference.
