[AFMUG] Mikrotik-tik-tik-tik

[Adam Moffett via Af]

So I've got several setups like this: CCR <-> SFP <-> Fiber <-> SFP <-> 
RB2011
sometimes pinging the RB2011 I can see this once per second delay. Those 
pings are at an interval of .2 seconds (ping -i .02) so you can see the 
delay on every 5th packet corresponds to a once per second "tick" of 
some sort.  If I vary the interval, the tick still occurs every one 
second.  I have multiple installations that do this, and multiples that 
don't....and I cannot find any rhyme or reason to it.  Connected to one 
CCR on SFP2 I have an RB2011 that has the symptom, and then I made a 
virtually identical installation on SFP3 that doesn't do it.  The only 
thing different is the IP addresses and the length of the fiber (3 feet 
on the good one, a couple thousand feet on the bad one).

The delay varies anywhere from a few ms to upwards of a hundred ms, and 
when it's high it affects VoIP so it is a real issue.  I have a few more 
combinations of things to test, but I wonder if somebody has seen this 
already who can save me a ton of time.  Anybody?

P.S.:  I emailed supp...@mikrotik.com yesterday.  Do they eventually 
respond or is it a blackhole?
