[AFMUG] UDP throughput is fine, TCP is bad?

[TJ Trout]

I have a set of Mimosa radios that when installed 3 weeks ago reported
500mbps mac rate and that was confirmed with the radios internal speed test
as well as btest between two CCR's in both TCP and UDP, everything was
great until I upgraded to beta software and I started seeing a problem
where the radios Phy/Mac/Speed test are all the same as prior but when
doing btest between two CCR's I can get 500 udp but only about 5-40 tcp!

I promptly downgraded software and I'm still seeing the same problem.

Any ideas?

Re: [AFMUG] UDP throughput is fine, TCP is bad?

[TJ Trout]

The radios are set 75/25, one direction I can do ~450udp and ~40tcp, the
other direction I can do ~120 udp and ~100 tcp, what gives? For 3 weeks
they were always the same TCP/UDP it's almost like the firmware damaged the
radio!

[TJ Trout]

What is even more strange, is I seem to have exactly a 3mbps per tcp
connection limit, when doing btest, I can get 3mbps @ 1 connection, 30 @
10, 60 @ 20, 120 @ 40, etc... Anyone ever seen this?

We ran into a similar problem on a unit that had been running for a couple 
months.  Make a couple changes and whammo, similar problem.  Rebooted, problem 
went away and I haven’t seen it since.

The most common cause of this sort of symptom is a speed/duplex
mismatch on an ethernet port.  Check them all (both sides of each link)
until you verify this is not the issue.

Even if I'm seeing full speeds in UDP? I checked both radios and both
routers and they all say 1gbps full duplex

What about pause frames? Are you getting any Rx or Tx pause frame counts 
on any interfaces?

Re: [AFMUG] UDP throughput is fine, TCP is bad?

[TJ Trout]

Well Butch, you were right!

If i set the master side radio to 100FD I can get 100/100 tcp no problem.
If I set the radio to 1000FD or auto the problem still persists.

If I set the CCR it's connected to, to either 100FD or 1000FD (uncheck
auto) I loose connectivity completely.

Any idea what the solution might be? Could it possibly be that I'm using
the GIGE-POE-APC for injection?

Re: [AFMUG] UDP throughput is fine, TCP is bad?

[George Skorup]

Yeah, you can't have auto on one end and forced FDX on the other, it 
won't link. The only things I can think to try is 1) reboot the CCR 
(eww, but sometimes necessary), 2) uncheck all but 1000M Full in the 
interface's advertise list (on the ethernet tab).

Re: [AFMUG] UDP throughput is fine, TCP is bad?

[Glen Waldrop]

I've forced it on one side in a few situations, works for me 90% of the time. I 
recognize it isn't suppose to, but it does.

The "advertised speeds" in the MT equipment is nice.

I've also had constant duplexing issues with the CCR. It would not connect to 
several devices unless manually set. The others were set to auto. The cable guy 
has decided to put it in plant again against my recommendations. Hopefully MT 
got those problems straight.

Re: [AFMUG] UDP throughput is fine, TCP is bad?

[Adam Moffett]

TJ,

What did you end up finding here?

I think I have something similar happening with a CCR plugged into a 
Ceragon IP10.  Every port claims to be running at 1000 FD.  I can get 
the maximum licensed speed of the Ceragon with UDP, but only about 
30mbps with a TCP connectionand at most 90mbps with multiple TCP 
connections.


With auto-negotiation they do 1000FD.  If I force 100FD on both ends I 
get pretty much 100mbps and it's beautiful (albeit only 100meg), but if 
I force gigabit I get no link at all!


Thanks,
Adam
