v6.42rc [release candidate] is released!

soonwai · Sun Mar 18, 2018 8:59 pm

I'm getting this error "no such item (4)" when enabling or disabling the pppoe client interface. Router is RB750Gr3 6.42RC43.
Note that this problem is not unique to 6.42RC43. I've encountered it before. It's just that I've only started looking into it now.

If I do a "/interface disable pppoe-out1 " then wait more than approximately 16 secs, and do a "/interface enable pppoe-out1 ", I will receive the error "no such item (4)".
Less than approx 16 secs, no error.

If I try the above with an ethernet port, no error.

Same thing happens on an RB2011UAS-2HnD running 6.42rc41.

Not a big problem, more of an annoyance, during normal use but wreaks havoc with scripts that takes longer than 16 secs between disabling and enabling the pppoe-out1 interface.

I faced this kind of problem in WinBox a few times (enabling ipip and eoip interfaces, AFAIR) on ~v6.40-41

Hi strods,

can you please confirm that above line means the fix for the problem of boot loop on hAP ac^2 reported by Keyko, and confirmed by me and psannz in this forum topic? If yes, I will try to upgrade RouterBOOT in the evening on my hAP ac^2. Thank you!

Update regarding 6.42rc latest release:

We have made a potentially significant improvement for wireless Nv2 PtMP configurations in the latest 6.42rc version release.

Those of you who are willing to test rc versions on your test network, please upgrade to the latest version, test the performance and report to support@mikrotik.com with the results. Your effort and feedback will be highly appreciated.

Please note that rc versions are released strictly for testing purposes and should not be used on crucial network devices.

We have made a potentially significant improvement for wireless Nv2 PtMP configurations in the latest 6.42rc version release.

Before such protocols are of any use to us, we need you to implement airMAX, the other guys to implement NV2, or you both agree
on a standard that both can implement. We invariably have a mix of different manufacturers of user equipment and now can
only use bare 802.11 or it will not be compatible

All the changes are on the AP side so you need to upgrade the AP. Client version can stay the same.

Hi strods,

I can confirm that the RouterBOOT firmware upgrade to 6.42rc46 works, and it is not causing boot loop anymore. However I noticed that after firmware upgrade (and only after Firmware upgrade, not ROS upgrade), the total memory and free memory shows much less than before. Instead of ~256 MB now it is ~128 MB.

              
              free-memory: 79.1MiB
             total-memory: 106.3MiB

I reported earlier in another topic that interestingly my hAP ac^2 unit came with 256 MB unexpectedly, and a colleague from MikroTik support stated it that some unit came with more memory. Can you confirm that MikroTik now limit by intention the available memory in this new firmware just to meet the specs, even though the unit has more memory physically, or was it a software bug?
Thank you.

I am having trouble with setting up a CAP AC using the 'quick setup'. Everything was fine until I rolled the last couple of RC updates. I am trying to set up as 'Home AP dual', and configure as before. However it refuses to get an IP address and then I cant access the device thought winbox as it refuses the connection. This then requires a manual reset if the device, but nothing seems to work when setting up with the 'Home AP Dual' quick settings. I have internet back now by using the 'WISP' quick setting and configuring that....

I am a no expert, but it's strange I had no problems from a few RC versions ago.

Not what you ask for, but you can send you log to syslog.
Install Splunk and you get an amazing log tool for your Mikrotik.
See my post here:

tigro11 · Sat Mar 24, 2018 7:35 pm

I saw the Splunk installation, but I tried not to commit a machine to mount the Splunk server. On PFsense I use NTOPNG, unfortunate that on mikrotik you can not install as memory could be used or USB sticks or better still the Micro SD. I need it because I have to keep track of the surfing of my hotspot. If you have a solution to track without engaging a computer as a log server it would be a great thing
now i use this solution.

When you have special requirements that require a special program which isn't available on MikroTik, and you
do not want to spend a lot of money on a dedicated computer, consider using a Raspberry Pi or similar SBC.

Synology NAS can do it if you install the Log Center package and configure it as the syslog destination for your Mikrotik. QNAP probably does something similar.

How do I tell RouterOS how many queues I have allocated on the hypervisor or does RouterOS set them equal to the number of CPU cores?

Per CPU, I think. Check with

Can anyone tell how comes the differences of them are so big?

mkx · Thu Mar 29, 2018 2:22 pm

When you compare tests made with different tools (e.g. iperf VS. CIFS) you have to be aware of behaviour of test "tools". Tests done using iperf are not affected by latency much (apart from usual TCP slow-start) while some more "chatty" protocol (such as CIFS file transfer) can be affected by larger latency quite much.

In your particular case one needs to know what was latency during CIFS test (and latency with idle connection) and it might become quite obvious why CIFS shows so much worse results than iperf. Or it might not.

I work for mobile network operator and when we are measuring pure radio performance, we allways use iperf (and UDP). If such "raw" test shows good performance, then the rest is lost elsewhere, either other parts of network or is artefact of application. One example of application affecting tests was when using Ookla Speedtest on Android: we were consistently getting much worse results when running Speedtest directly on smart phone than when running Speedtest on laptop with USB tethering between the very same smart phone and laptop. We attributed the difference to the fact that phone's CPU was unable to process all data in due time. We also observed negative impact of app when testing latency. Speedtest, run on laptop, was giving us say 30ms RTT but we were able to show that reply from server arrived into the laptop after say 22ms ... but app took another few ms to process data. We couldn't say when additional delay occurred (at TX or at RX or both), but that's about how correct tests can be.

With the Unknown Unicast/Multicast Flood disable button being added in to the bridgeports, is there a way we can get that added to PPP profiles similar to bridge/bridge priority/cost/horizon? OR have a bridge-wide default option for it to be either on or off? I'd rather it DIDN'T default to "on"

Thanks

Thank you very much for responding my post. Based on your information, I have already learned more about network bandwidth, throughput, and latency.

Based on the results of MikroTik Bandwidth test on hAP ac^2 5G ac and hAP ac lite 5G ac, they show that the firmware V6.42RC52 on hAP ac^2 has to be finely tuned to achieve a stable and nearly flat performance otherwise the sales order for this product will drop tremendously due to poor and unstable performance.

In summary,

1. Bandwidth - can be determined by iperf3, MikroTik bandwidth test

2. Throughput - can be determined by actual file transfer or the equivalent area in MikroTik bandwidth Test

3. Latency - can be determined by ping command.

I also have Mimosa and there the DFS even takes the network down longer. Up to some 15-20 minutes. Partially also because when the AP if 'free'd' from the DFS it takes a long time before clients are associated back and in full running mode again. Actually, if your Mimosa P2MP network is hammered by DFS you might as well not use is it at all....... completely unusable. You have to find a band/channel that has no radar or no DFS restrictions. Only then it works. (there is no way of avoiding DFS in Mimosa product line, as we can with MT.

I understood it.
I'm playing with capsman ant 5 access points, At first time I did not understand why there is no wireless connection...

But I think it will be better if in satus window will show not only detecting radar but countdown timer, so you will known exactly when detecting will end.

I have already created another thread concentrating on the status of the WiFi problems found in hAP ac^2 in the following thread.

viewtopic.php?f=7&t=132648&p=651986#p651751

Even applied the most recent RC (V6.42RC52), although the speed for 5G WiFi has already been increased from 20Mbps to 90Mbps, which is much below our expectations. We want the device to be capable to download file at a steady and stable rate of 500Mbps over at least an hour and not just few mini-seconds..

PPPoE Server not work into VLAN Interfaces
reverting back to 6.39.1 that works perfectly
tested with RB3011 and CCR1009

I use a vlan to deliver to each neighborhood or sector,

/interface bridge add name=LAN
/interface bridge port add bridge=LAN interface=ether5
/interface bridge port add bridge=LAN interface=ether6
/interface bridge port add bridge=LAN interface=ether7
/interface bridge port add bridge=LAN interface=ether8

/interface vlan add name=POP-CENTRO-SECTOR-LESTE interface=LAN use-service-tag=yes vlan-id=100

/ip pool add name=PPPoE-RES-1M ranges=172.16.11.1-172.16.11.126

/ppp profile add dns-server=172.31.255.2,1.1.1.2 local-address=1.1.1.2 name="1 MEGA" rate-limit="1M/1M" remote-address=PPPoE-RES-1M
/interface pppoe-server server add disabled=no interface=POP-CENTRO-SECTOR-LESTE default-profile="1 MEGA" service-name=BRAS1

Arriving in the neighborhood, i untag the vlan in the sectorial wlan like this (into my sectors SXT SA5).

/interface bridge add name=bridge1
/interface bridge port add bridge=bridge1 interface=wlan1
/interface bridge port add bridge=bridge1 interface=ether1
/interface wireless set [ find default-name=wlan1 ] vlan-id=100 vlan-mode=use-service-tag

the PPPoE server shows this looping log:

jan/01 21:04:16 pppoe,info PPPoE connection established from D4:6E:0E:BC:E2:FB
jan/01 21:04:16 pppoe,info PPPoE connection from D4:6E:0E:BC:E2:FB was already active - closing previous one

it is not a problem of the sector nor the wireless configuration this also happens by cable or fiber, untagging and dialing with any other brand that is not RouterOS not only works RouterOS dial PPPoE, can test, it is not a configuration problem, because everything worked perfectly in earlier versions,

I apologize for the long thread in the forum, but I've been posting a lot of time on the forums on Release Candidate until now, never solved.
reverting back to 6.39.1 that works perfectly

I should have been more specific. Does it affect 6.41.3, or was introduced on this RC? Is it a problem with the wildcard no matching at all? Or matching too much? Or just matching incorrectly?

TIA

pe1chl · Thu Apr 05, 2018 5:11 pm

L2TP/IPsec works OK on 6.41.3 so it must have been introduced in the RC (or it is a problem I don't notice...)

Yep, it was introduced in RC, just a few versions earlier. I noticed it on default configuration.

Hi strods,

We set queues equal to the assigned CPU cores and upgraded the router. After booting RouterOS there are no entries in '/int ethernet'...

jfmt · Wed Apr 11, 2018 7:04 pm

Hello.

Maybe this bug or feature.

I use 6.42rc56 CRS317-1G-16S+ for build bonding (LAG+LACP+HW Offload) with HP G8 server with Ubuntu 16.04.3 LTS

I use Mikrotik as DHCP Server, Linux work as client. DHCP, ICMP work good. But from Linux over bonding interface in schem one i can't connect to Mikrotik SSH. Firewall empty. I use Mikrotik as DNS server, but from Linux name not resolve. In tcpdumps all look good, but not work.

Network card type same at all servers.

09:00.0 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01)
09:00.1 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01)

Linux servers bonding configurations.

# Bond

Mikrotik configuration.

/interface bridge

/interface bonding
add lacp-rate=1sec min-links=1 mode=802.3ad name=bond_S1 slaves=sfp-sfpplus1,sfp-sfpplus2

/interface bridge port
add bridge=bridge_servers interface=bond_S1
add bridge=bridge_servers interface=bond_H1

When i change configuration to active-backup mode at one server. I can ssh/resolve to Mikrotik from any servers.

# Bond

add bridge=bridge_servers interface=bond_H2
add bridge=bridge_servers interface=sfp-sfpplus1
add bridge=bridge_servers interface=sfp-sfpplus2

All other configuration at Mikrotik same. I attache support.rif in Ticket#2018041122005401

Can you help resolve this problem?

12.04.2018

When i disable hw-offload on 802.3ad bond interface all start work. When hw-offload enabled i can't connect to servers from Mikrotik.
I found workaround. Add empty EoIP interface to servers bridge and now all look working. Later i understand that this not solve problem.

14.04.2018

After some tests i found that communication randomly stop from H1 to S1, for example after one hour more or less. Up/Down bridge interface fix problem but only for some time. I check fault tolerance by logicaly shut one interface of bond, all traffic go one interface. After unshut interface traffic no comeback. This results not for production use. I move to active-backup with ARP monitoring. This without load balance but work. I not try downgrade software. If somebody have information about problem like this write it here.

19.04.2018

Mikrotik confirm this problem in ticket #018041122005401. I change schem and add VLAN because need seporate INET from MGMT. Still want use hw-offload for VLAN. But now i have another problem. I can't ping CSS326-24G-2S+ from CRS317-1G-16S+. If i disable hw-offload on port SFP16 all start work. If i shut/unshut bridge all start work.

Maybe this other problem.

Sorry English no my native language.

Thank you.

so there is two tests, one test and after few seconds - second test.

no changes, no move just chrome open new tab and repteat test
DL 2.75Mbps / UL 102.40Mbps

Upgrading RouterOS x86 to 6.42rc56 on a reset configuration results in multi-queue VirtIO appearing to initialise.

Some questions:

I assume we should disable RPS?
Shouldn't the IRQ counters be incrementing on other queues? Perhaps someone running multi-queue vmxnet3 could compare?

Herewith a screenshot of multi-queue VirtIO. IRQ appear to exclusively increment on the first queue:

Herewith our settings:

/queue type
add kind=mq-pfifo mq-pfifo-limit=10000 name=mq-pfifo-10k
