Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

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...

Re: v6.44.2 [stable] is released!

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?

Re: MikroTik News December 2018 (Issue #86)

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...

I already opened a ticket once and they first suspected a hardware issue, but as the fans start to bahave well ag...

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.

You don't have to buy a license unless you want to upgrade to a higher license.

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...

L2TP client change destination port away from UDP 1701

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.
