Hi there,
I'm completely new to Mikrotik switches and bought 2x CRS326-24S+2Q+RM switches. So 2x 40Gbps and the rest 10Gb SFP+. And somehow I can not even get a working VLAN configuration. I'm following the exact manual examples, but still it does not work.

I have 2 servers, an ESXi host and a Storage host and i connect them to the 40Gbps interface.

Switch 1:
Port qsfpplus1-1 (name=Uplink-sw2) = Uplink to switch 2
Port qsfpplus2-1 (name=qsfpplus2-ESXi) = ESXi Host

Switch 2:
Port qsfpplus1-1 (name=qsfpplus1-SAN) = Storage Host
Port qsfpplus2-1 (name=Uplink-sw1) = Uplink to switch 1


Leaving everything default, without any vlans configured and one bridge, i can make the connection from the ESXi host to the Storage. All traffic goes over vlan 1. But as soon as i configure vlan 6, set the uplink as a tagged port and enable vlan filtering, communication stops. In SWOS everything works perfectly, so no vlan issues here.

I keep the config between the switches the same and simple. I know i don't have to set the untagged interface in the bridge-vlan, because RouterOS sees this automatically in the pvid config of the interface. But still, it does not work.

Also tried ingress-filtering=no on the uplink interfaces and bridge interface, but that does not work either. So enabled it on all interfaces and the bridge.
Tried differtent RouterOS versions and i have this problem with all versions.
I'm lost....What am i missing???

Ps. VLAN's work perfectly in SWOS, but I have a link detect issue in SWOS. When a server reboots, the link does not come up. I have to manually set the interface on the switch to autodetect or fixed 40Gbps (whatever it previously was set at) and then the link comes up. This problem does not exist in RouterOS. In RouterOS the link comes up after a reboot of a server without any issue's. So I only want to use switching in RouterOS.

See my signature.

What manual example are you following?

I don't have any CRS3x switches, but it seems odd to me that you have added ether1 to the bridge, but then are adding an ip address to ether1.

What I would have expected was to add a vlan interface for a specific vlan, and then to associate ether1 with that vlan in the /interface bridge vlan section.

Have you done a search for CRS3xx vlans on youtube? There's a good video Mikrotik VLANs - CRS3XX Step by Step - Mikrotik Tutorial by the Network Trip.
