Hi.

I need to know if RB600A to RB600A with ROUTED (no WDS) 11n link can push more than 22-25Mbps of tcp packets.

I have -62 signal on both chains (switching pigtails keeps same signal levels), Compex WLM200N5-23-ESD radios on both ends with 1m LMR-400 cables, 30cm Pigtails and Dual-pol panels 17dB (not known antenna brand). Radios are tested and on StarOS (x86-PC) work as expected.

Test is performed via IPerf (PC-PC, tcp packets) with 10 streams, and that same test can push 100Mbps (switch limit) via LANs in bridge mode.
Wireless Modes tested were nv2 and nstream. Rates stay on 270/270. Tested on several clean chanells

If RB600A IS capable to push more, I will post all asked info, to see where is the problem.

do you have 2 rb4##ahs handy to do the same test with? Im curious if the 600A just has (timing|backplane) problems... The CPU on ours is higher than all other types of boards with less traffic as well.

No, no MT boards of any sort handy. It was done for a company that demanded MT gear. I use StarOS on my network on X86-PC or ALIX. I know it by heart.

I can also find my way arround MT/RO very well, on both Winbox and terminal/ssh, but lack first hand experience with different hardware. RB600A were taken because of 1GBps LAN's (ordered back in September but reseller managed to deliver wrong gear for almost everything else so wew were stalled until 2 months ago when we started (re-)building sites).

I tested RB600A with 2 RB 1x1 radios bridged and bonded, and got high speeds in bridged mode, but was not fluent with MT hardware to be aware of the bridge vs routed model. But in the field and on routed network it fails miserably.

I forgot to mention that I use ROS 5.2. Is there larger perfomance issue compared to ROS 4.1x?

Yes the RB600A can push alot more then 25 Mbps when they work.

A word of caution. I have had to replace all 25 RB600s I've deployed some A some not A. They were all ordered at different time periods, months apart. There are 5 capacitors that leaked on all 25 of my boards after around 9 months -12 months in operation. Caused unreliable mPCI operation, and random reboots.

If I were you I would get rid of them.

Cheers

Strange. I've got 3 RB600 and 1 RB600A, 2 and a half years, no problems so far. Two of them are fully loaded.

What were you using to power them?

On topic, the best I've seen was a little over 20Mb, but I haven't really stressed it. I haven't had the opportunity.

I am going to put together relevant data tomorrow and post it.

Please notice that I am talking about ROUTED network, no WDS or BRIDGE, as most people use them.

OK, we found the culprit.

It seams they have some shity network router in their NOC unable to pass more then 25Mbps of traffic.
I do not know if this is because of some malfunction or it is old, but they tested within the NOC and stumbled on it.

Thanks all for reading and responding.

Some were powered with 48V DC power supply's, some with 18V DV power supply's, but most of them were using industrial 48V x 1A PoE injectors.

The only boards that showed problems were boards with 2 x mPCI cards in them namely high powered XR2 and XR5.
The capacitors were the ones that went to the mPCI slots. The control routers on my towers were all RB600A all had leaking caps but never experienced any issues (no radio cards), I would estimate that we had them running for ~2 years as well before we replaced them. Typcial load on the control routers was ~25 Mb/s but could see as high as 40 Mb/s so not stressed but enough to say they were being used.

to OP, glad you tracked the issue down.

Noted. I'll get my climber to check it out next time he's up there.

I'm only running one high powered card per RB600, but better safe than sorry.
