Hi All, is there an actual way of making mikroik routerboards work when on a fixed duplex and speed setting ?, like one that actually works ? I am so tired of trying to get them to lock onto a speed and duplex only to have them get a mind of their own after a reboot or anytime in the future at all and then stop talking to each other. Even when talking to each other they seem to hold no regard for any hard set parameters and just randomly go to 10M half duplex or something stupid for no reason. When we operate 5 or 6 pieces of gear at a site we need to have some confidence that they will actually be able to communicate with each other, hard setting network speed and duplex is good practice and should really be done on all networking equipment when you are in control of both ends of a line IMHO, but damn Mikrotik's have a mind of their own in this area and I am really sick of fighting with them. Any advice would be appreciated before I lose all remaining hair ! Regards Paul
That sounds frustrating. Gan you give us more info. I have 250+ Mikrotik kit in the field and never seen anything remotely like what you are describing. What models and config ? Very odd. Matt On 12/07/2016 9:31 AM, Paul Julian wrote:

Hi Matt, we have probably about the same amount as you, a mix of wireless and non-wireless units, so anything from an RB450 to a CCR 36 core, but the latest one is a site where we just upgraded our radio from an Omnitik to a Netmetal with 20Dbi Sector, when doing this we kept the Omnitik as a backup radio and the installed a Powerbox (RB750P) in before it as a switch basically and to do the POE, leaving everything as Auto the netmetal connected at 10M half duplex one minute, and 100M full duplex the next, flapping between those pretty much, then the Omnitik starts doing the same, we have seen this a lot but it only seems to happen with POE is in play somehow, either from the port or an injector. So we hard set the ports to all be 100FULL on all gear and then we lost the netmetal, so we powercycled the netmetal and it came back at 100FULL and was fine. I don't know what it is but we seem to have so many problems with duplex and port speeds, I just don't get it. We always use Mikrotik POE injectors or POE directly from a port on a Mikrotik so we try to be 100% compatible in all areas like that. It's just Sooooo frustrating !

Is the cable particularly long or anything. I have quite a few SXT's running setup's like you are with your netmetal. Once I saw something like you are describing. But it was not a duplex problem Just a voltage drop issue. I had a 2011 power feeding a SXT over about 200m of cat5 It appeared like the duplex was moving around but after putting another 2011 in place of the SXT and and a console we saw the unit was in fact just rebooting. It took some work but the voltage drop was to high over that distance. We used an injector instead and used a higher voltage power supply (35vdc) which ended up begin about 29v at the other end. (watch your voltage drop here you dont want to blow up your router) Problem solved. Perhaps try power at the far end if you can to eliminate a power feed issue. I have always fond Mikrotik's duplex negotiation to be rock solid and the ability to advertise wanted speeds works very nicely. Matt On 12/07/2016 9:58 AM, Paul Julian wrote:

Sounds like a cable or voltage drop problem to me - I've had a variety of weird issues caused by those two. Check your terminations are all good, check the cable hasn't been damaged (try another cable if you are able to) and check the voltage on the remote end. If possible, try injecting power closer to the remote end too (just as a test). -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Paul Julian Sent: Tuesday, 12 July 2016 9:59 AM To: 'MikroTik Australia Public List' <public@talk.mikrotik.com.au> Subject: Re: [MT-AU Public] Speed and Duplex on Mikrotiks Hi Matt, we have probably about the same amount as you, a mix of wireless and non-wireless units, so anything from an RB450 to a CCR 36 core, but the latest one is a site where we just upgraded our radio from an Omnitik to a Netmetal with 20Dbi Sector, when doing this we kept the Omnitik as a backup radio and the installed a Powerbox (RB750P) in before it as a switch basically and to do the POE, leaving everything as Auto the netmetal connected at 10M half duplex one minute, and 100M full duplex the next, flapping between those pretty much, then the Omnitik starts doing the same, we have seen this a lot but it only seems to happen with POE is in play somehow, either from the port or an injector.

On the particular Netmetal I am referring to in this instance the voltage is 27.1V and the cable run is only about 10M, the powerbox which feeds it interestingly shows it's voltage at 26.7V and it is fed via cable from the batteries, but those voltages are still heaps. The cable has also been replaced with brand new outdoor rated CAT6 with shielding and drain wire. This particular site is a solar site as well so power is really stable because it is on batteries and has 10 times more capacity than it ever needs, but this is just my most recent example, we seem to get this problem on almost every new site install now, solar or not, once everything reboots and settles down it seems OK, I get concerned about doing reboots again though as it can cause the issue to re-appear for no apparent reason and when the problem is on a roof it makes it a bit more complicated to address. What are the opinions of the quality of the Mikrotik supplied POE injectors, is there a chance it's these and we should replace them with something better perhaps ? As I said earlier I reckon if I thought about it enough I could probably say that it was only devices which were powered by POE somehow.

Hmm Batteries. What sort of isolation do you have between the battery and the injector. Perhaps there is something going on with in the natural R/C network within the battery. But then you said some are not solar. So very odd. dont suppose you could run two cables to the radio one for power distribution and one for the Ethernet. You should not have to but something is going on that's unique in your setup. Matt. On 12/07/2016 11:02 AM, Paul Julian wrote:

One obvious if clunky solution would be a simple scheduled script that sets up speed/duplex the way you want them every (say) minute. A slightly less clunky solution would be to set it only if not already correct. This could be combined with logging to give you some accurate info on how often and and on which devices it is happening. You may find some regularities in the events that get you further towards a resolution.
Even when talking to each other they seem to hold no regard for any hard set parameters and just randomly go to 10M half duplex or something stupid for no reason.
After one has unexpectedly changed, do you see anything in the logs around the time of the change? It does seem odd that a hard set parameter would change, unless the actual interface itself is "disappearing" somehow and upon return is a "new" interface and thus has all defaults/auto settings. Are other hard set parameters changing at the same time? A comment or name would be a cheap and harmless "hard set" thing to set and watch. I have never set duplex or speed; I have always allowed the auto settings to do their stuff and it has always seemed to work. Are there other, possibly non-obvious, settings related to the duplex/speed settings that could be conflicting or taking priority?

Thanks for your reply Karl, I am baffled by it, but somehow convinced that it's something broken in the POE department, however I'm with you, I don't see how if something is hard set to 100 FULL on both sides that it can talk one minute and then not the next ! Usually it's when leaving stuff as all Auto and then something goes wrong that I change to hard set, but then you still see problems as well.
