CRS326 with 6.41, best bridge or switch

RouterOS General
1

I am setting up a couple of CRS326 (routerOS) to connect via 10G connection two esx servers. On the esx systems the jumboframes are enabled, and we are having issues with large packets going through mikrotik, also I would lilke to get a good performance and I have a couple of questions.

  • With version 6.41 the penalty of using bridges is much less as before thanks the hardware offloading (link), is it recommended to use them so it’s easy to segmentate the ports?
  • Enabling mtu mtu=9000 on the bridge will be enough when using a bridge (i guess the it is)
  • If not using a bridge, do I have to enable the mtu per interface? Is there any global setting?

I searched a lot in the forums, but there’s not many information on 6.41 changes yet.

If you use switching performance should be much better.

You should still be able to create multiple switch groups to segment the ports.

To set mtu of all ports you could use

/interface ethernet set mtu=9000 [find]

Could you provide me a link for an example? I followed up to this link, but on that page there is only mention of creating bridges (no switches). My understanding after reading the documentation is that it depends on chipset features (that I though the CRS326 doesn’t have)
I take note of the other annotations, thanks
I just tested your command and I had to change also the l2mtu value to be able to change the mtu. So the final command is:

/interface ethernet set mtu=9000 l2mtu=9000 [find]
