In SUP-51076 I am discussing memory leaks in the DNS resolver and was requested to test an internal beta56 which unfortunately was not available in the architecture of my test router.
Now I see this rc1 and this item does not appear in the changelog, also it appears not to be solved (still testing).
I still see the "cache used" in IP->DNS increasing without new items being added in IP->DNS->Cache (but repeated queries being made).
When the cache size limit is reached, I see items disappearing from the list. It looks like there still is a memory leak.

Good to see that the restore of backups is possible again. A very important function when updating to a next version.

I hope that this will be also tested by Mikrotik self, each time a Beta/RC/incremental/main release is made. Not leaving that over to the users, who then are not pleased to go, the long way to restore the config by hand.

I know it's hard to believe, but we do test versions before release. Sometimes for weeks. Both by using them and also in automated tests.

On heavy load "30%"!!! on CCR1036-12G-4S (r2) (345 PPPoE sessions)

again this error

log error code

snmp,warning timeout while waiting for program 20

ONLY AND EXCLUSIVELY when monitored from The Dude 6.47.10
no other devices allowed to monitor SNMP
SNMP version used: 2 (2c)

On the dude the only 4 things monitored:
1) ping
2) iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoAAASessionMIB.casnMIBObjects.casnActive.casnActiveTableEntries.0
3) iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrHealth.mtxrHlPowerSupplyState.0
4) iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrHealth.mtxrHlBackupPowerSupplyState.0

After that error the RouterBOARD is less reactive and, on short time, all ways to connect to the RouterBOARD stop working,
webfig, winbox, mac telnet, telnet, SSH (API not tested).
The only ways to reboot is to turn off the power or wait for the watchdog, which is set to reboot immediately,
but fails to reboot the router right away and takes more than 10 minutes.
In meantime between error log and watchdog reboot, all user still working like the RouterBOARD is not "locked".

Obviously I can not make supout.rif on that moment because I do not reach to access to the RouterOS.

I certainly believe that, however this slipped through for several if not all versions of the current Beta. It is like upgrading the firmware of your Tesla for more functions only to notice that brakes don't work anymore, because of that upgrade. You can't go back to a car with brakes or even worse you note then it when you have to slow down the car.

w60g - limit power output when using region EU to match EN302567 on nRAY;
This is due low gain antenna? WHich is the difference from LHG60?

This is more like airbags are broken - something you usually do not need or test, but that is really important in special situation.

What about connecting to the router with console cable ? Have you tried that ?
Good question, same answer as other identical questions on similar problems:

I can't wait an hour to restore the service, driving 100Km away for test if serial cable work or not...

OOB connectivity is essential for SPs. we even built a dedicated network on different access technology (LTE) to cut down reaction time.

This is _OT_ and, everytime, the topic go _OT_ because someone instead to try to understand the problem,
it suggests other things that have nothing to do with it.

Does putting a backup line prevent the RouterBOARD from giving that error and stop working? (Not, obviously)

I do not wrote about rings, LTE and other than I have onsite because is not that the point and is irrilevant.

And yes, I put that on failovered production machine, because I do not have a lab to replicate 350 true users...

Instead the @durkonos question, is a good question, but I do not have nothing connected on serial console onsite.

Well, when he installs an rc [testing] version on a router 100km away I presume it is more of a hobby SP than some critical thing...
I don't even do that on our HAMNET!

This is due low gain antenna? WHich is the difference from LHG60?
nRay and LHG 60G is supposed to be capable same link lengths. Why to lower power limit for the nRay and not for LHG 60G? How that will play out?

*) mpls - allow to disable FastPath (CLI only);
Big thanks for this, MikroTik! Now with the ability to turn MPLS FastPath off, the feature to automatically copy MPLS EXP bits on ingress to VLAN Priority (PCP) on egress actually works again for the first time since MPLS FastPath was added - basically since RouterOS v5. This feature was only working correctly on CHR since it was the only platform without MPLS FastPath. I no longer have to create extra single port bridges and bridge filters to force MPLS FastPath to turn off, and will now be able to delete hundreds of extra bridges that are otherwise not necessary.

Wouldn't the correct solution be to add EXP --> PCP support to the MPLS and VLAN FastPath modules ?

Yes, it would, but I didn't want to push for this in v6. Probably the person who wrote that code no longer works at MikroTik and so it might be asking too much to carry out a significant fix like that in v6, and this may very well no longer be an issue in v7 with the extensive routing rewrites (I haven't tested yet). I will be pushing for this in v7 if MPLS FastPath has to be turned off for this to work, but at least turning off FastPath is a better workaround than having to create many extra bridges.

Also, before this, I was only 80-90% sure that MPLS FastPath was the cause of the issue -- not 100% sure -- without the ability to turn it off to confirm. There should always have been the ability to disable the MPLS fastpath handler to troubleshoot issues, just like the controls we have for IP fastpath and bridge fastpath for the same reason. Being able to turn off MPLS FastPath means that, as of today, I can now be 100% sure that the problem is there, because the feature suddenly starts working when MPLS FastPath is turned off, and stops working again when MPLS FastPath is re-enabled.

Maybe in the UK it is about that EMF thing, but in EU it is about EN302567 which limits EIRP to 40dBm (like it is limited to 30dBm on 5 GHz).
No idea why the change is specific for nRAY, maybe it was reported for that device or they tried to certify that device.

The EN302567 is limiting the output power to 10w eirp to comply with the new EMF rules
All radio transmissions above 10w eirp in the UK have got to now comply with minium distance rules

Yea, it wasnt until the second post that I caught on as well. I think it was a subtle way to publicly acknowledge and poke fun at themselves for that 7.1rc4 changelog.

Re: v6.49rc [testing] is released!

Mon Sep 27, 2021 5:37 pm

Have there been any changes in "source address selection" for locally originated packets (from the DNS resolver in particular) since 6.48?
I am investigating a problem in that area that appears to be introduced in 6.48.x and that I cannot reproduce in 6.47.10 and 6.49rc1.
But I do not see a changelog item that could be related to this.

The issue is related to having multiple route tables (/ip route rule) for different networks, where the correct behavior would be to lookup the destination address of the packet (in this case DNS query, and destination looked up in the list of DNS servers) using the ip route rule and then the matching route table, and find the preferred source address in there and send the packet with that source address.
It looks like in 6.48 the step of matching the ip route rule before looking for the route is skipped, and the packet is always sent using the main table with the source address found there.

Has there been any fix for this? I have difficulty creating a minimal demo setup for the problem on 6.48 but I see the effects of the problem on several routers in our network.

Now how can I say this nicely: These self-proclaimed "IT Experts" don't disappoint.
Speed setting is already there, my best guess is that it refers to setting rate select to high/low for sfp modules that support it.
Example: https://www.optoway.com/upload/files/SFP/SPS-2541WG.pdf
RATE SELECT CONTROL
RX / TX rate can be independently controlled by RS0 / RS1 input pin (Hardware).
RS0 / RS1 input pins (pin 7 / 9) are used to select RX / TX rate.
Status of RS0 / RS1 input pin logic level is reflected to register byte 110 bit 4 / 5 on address A2h.
RS0 / RS1 input pin must be “High” for 32GFC or 25GE transmission and “Low” for 16GFC or 8GFC transmission.
To have flexible transmission data rate other than 25GEC, and CPRI option 10, user may assert TX and/or RX CDR Bypass bits (A2h, Byte 111, [7:6]) to bypass the CDR if required.

But hey, I'm no "expert".

I can confirm I see the same behavior here.

Some days ago I got the confirmation from MikroTik that they could now reproduce this problem (with the extensive description of test scenario I provided) and are working on fixing it.

I upgraded a test router that was on 6.47.10 to 6.48.4 and disappeared dhcp lease v4 and v6. I mean the customers got IP but they dont appears on Winbox on the routers. they remain in WAITING. The same behaviour is happening on the latest RC.
