MikroTik

drbunsen

If you're using Mikrotik AC gear then you're out of luck, 20MHz is the smallest channel bandwidth possible.

Don't get stuck in the past

Yeah, lets talk about Mikrotik and IPv6 or wireless or... ;)

drbunsen

What you'll most likely get: no answer from Mikrotik, as they don't care

drbunsen

Could you be more precise? Is there a way to identify the cause and what would be done during repair? Think about the folks which are running these switches now without flapping ports, but might run into problems as soon as CRS3xx are installed. We would like to know about the issue before the insta...

Hi,
I've not done it, but looking at the inside I would assume it should be possible:

drbunsen

I'm not sure if it was there before, but after upgrading a WAP AC I see a "W60G Station" tab in the wireless menu in Webfig.
Makes no sense on this hardware and should maybe be hidden on non 60GHz hardware?

drbunsen

Seems to be company policy to not answer difficult topics and to play dead.
Potential customers are being replied to with product proposals, but whoever already bought is left behind.

drbunsen

The standard might not require to use gaps for specific bands, as the intention is to keep the HF on the line. However using a unmatched line (the power grid) to transfer HF is a guarantee to send out unwanted transmission. The question is just how far these go and if someone in this range feels aff...

drbunsen

Hi,
not a fan of PLC as it uses frequencies not intended for this application and assigned to other services.
I hope that PWR-LINE AP at least does not use ham radio bands for the PLC transmission, otherwise you might get complains...

Hi, my working setup for IPv4 and IPv6 looks like this: /ip address add address=x.x.x.x interface=ether1 network=172.31.1.1 /ip route add distance=1 gateway=172.31.1.1 /ipv6 address add address=2a01:4f8:xxxx:xxxx::1 interface=ether1 /ipv6 route add distance=1 dst-address=2000::/3 gateway=fe80::1%eth...

Update is as with any other Mikrotik device. Upload the image (x86 for CHR) and reboot.

drbunsen

Hi, yes, that's normal. Forget about the idea of this device being silent. Even with 20°C room temperature on idle with no SFP the fans kick in regularly. Once you start to populate some SFPs and put traffic on the box it even gets hotter of course. Edit: Oh just remembered, when I got the CRS317 la...

drbunsen

Hi,
all devices with 16MiB store the uploaded firmware file in RAM. It overwrites the current firmware when the update process starts initiated by a reload.

drbunsen

I've updated a CCR1036 from 6.42 to 6.42.1 and webfig now only works on one of two configured IP addresses on the same interface.
Edit: Solved and not related to the update.

drbunsen

What if the fans are stuck in low RPM state and the box heats up too much if it's not able to control the fans anymore? Maybe this bug can be triggered while the fans are off...

drbunsen

I've observed this also a couple of times after 2-3 weeks of uptime. Then the fans seem to keep their last state (RPM) and even when the temperature is below 40C they don't stop anymore. I already opened a ticket once and they first suspected a hardware issue, but as the fans start to bahave well ag...

drbunsen

Hi, with the current RouterOS version the threshold seems to be fixed at 40C. If the CPU or any SFP temperature reaches this mark the fan will kick in until the temperature is lower again. I would love to have an option to change this threshold, but it seems to be impossible right now. I have one of...

drbunsen

OK, same for me. They are in sync and flashing like every 2 seconds if there was traffic on this port during this time. Doesn't matter if this was a single ping or many megabits worth of traffic.

drbunsen

Hi, on a CRS317 the "ACT" led is on if the port has a link and it blinks on traffic. This was the default setting on mine. > system leds print Flags: X - disabled, * - default # TYPE INTERFACE LEDS 0 * interface-activity sfp-sfpplus1 sfp-sfpplus1-led1 1 * interface-speed sfp-sfpplus1 sfp-s...

CHR on rc28: - disabled package dude - disabled package wireless - disabled package hotspot - enabled package ipv6 After reload, packages show correctly to be disabled/enabled, but in WebFig CapsMan, Wireless and Dude menus are still there and IPv6 one is missing. On the terminal IPv6 is there and t...

drbunsen

Very nice. I can confirm, rc28 is able to boot in Hetzner cloud. Thank you!

drbunsen

Regarding Hetzner, CHR would need to be able to boot from Virtio SCSI. Not a good example normis.

drbunsen

I've updated a crs317 from rc6 to rc18 and now the fan is kicking in regularly. It seems it's trying to keep the cpu temperature below 40C as this is the point when it stops again. There's nothing in the changelog about it and before that I've even seen cpu temperatures of almost 50C without the fa...

drbunsen

Hi,
as you're running different port speeds it's probably the same issue as described here? viewtopic.php?f=3&t=128843

drbunsen

You don't have to buy a license unless you want to upgrade to a higher license.
The HEX comes with a license level 4 and all it allows is and will be available to you on this device.

drbunsen

No, there is no switch: https://i.mt.lv/routerboard/files/RBwAP ... 162504.png

drbunsen

Only if you have such a rule. It will do exactly what you tell it to do. With no rule it will do nothing. Common firewall rules will look like this: - allow something - allow something else - allow another thing... - deny anything else And keep in mind you have to do this twice for both chains, &quo...

drbunsen

Hi, the features in RouterOS are identical on all Mikrotik devices if they run the same version. The difference is in the hardware and how powerful the CPU is. The CRS3xx have some features in hardware, older devices have to do it via the CPU... Regarding the filesystem, all new devices with 16MB st...

drbunsen

Sorry for being so brief. Just did this recently and still had the tabs open in the browser. Indeed the new vlan config seems to be missing or hiding well ;) Maybe I found this by trial and error. However, the vlans need to be configured on the bridge since the rc version. I have this in my lab setu...

drbunsen

Hi,
check the rc-changelog: https://mikrotik.com/download/changelog ... lease-tree
Documentation and examples:

drbunsen

Hi, I believe it's due to your bridge1 not being an untagged member in any of the two vlans. You can see the switch put it as dynamic in the default vlan1, so from there it should work. Try it from sfp-sfpplus3 which should be on vlan 1 and I guess it will work. Put the bridge1 as untagged member of...

Please support virtio SCSI storage controllers, see viewtopic.php?f=15&t=120413

drbunsen

Some time ago I've tried to install CHR on a Hetzner VPS, unfortunately I ran into exactly the same issue.
It would be nice if Mikrotik could support virtio SCSI storage controllers as well.

drbunsen

Hi,
mine runs also quite warm with gigabit ethernet connected and an AP active on each band otherwise idle.
It uses around 6 watts in this mode and the temperature readout says 56C in 22C room.
I'm wondering if this is healthy with this closed case in the log term.

drbunsen

OK, so it's not possible with a device on the border of the network

Would you please consider to add a variable destination port for L2TP in a future routeros version?

drbunsen

- The NTP server on 6.35.2 still remains in INIT state

I can confirm the same on RB3011 for v6.35 and v6.35.2

drbunsen

Not sure if I'm doing it right, just tried with: /ip firewall nat add action=dst-nat chain=dstnat dst-address=1.1.1.1 dst-port=1701 \ protocol=udp to-addresses=1.1.1.1 to-ports=10000 However, I still see packets leaving with 1701 as destination and the counters for this rule are not increasing. To b...

drbunsen

Yes, I've tried :port, but it's not being accepted as entry.

@mrz: Does "not directly" mean not at all or maybe possible with some sort of trick?

drbunsen

Hi,
I'm trying to configure L2TP as a client, but it needs to connect to a server which runs its service on a different port than 1701.
Is there any way to change the destination UDP port away from the standard 1701?
Thanks in advance.
