The /interface bridge vlan section, plus the pvid and vlan filtering settings under /interface bridge port, have no effect unless the bridge has vlan-filtering=yes.
You have incorrectly specified a bridge port, in this case sfp1, under /interface vlan - you should use the parent bridge, not a member.
Also ether10 is in the tagged list for vlan-ids=100 under /interface bridge vlan - it should either be absent, in which case untagged membership is dynamically added based on the port PVID, or explicitly added with untagged=ether10.
According to the wiki, the Mikrotik 3011 has no VLAN filtering. Or am I wrong?
Where do I have to configure the 3011 untagged?
/interface bridge port ?
or here
/interface ethernet switch vlan?
It has no hardware-offloaded VLAN-aware bridge support. This is only an issue if you have significant traffic between ports in the same VLAN, all the traffic from VLANs to internet and between VLANs has to be handled by the CPU in any case.
By far the simplest setup is to use a single VLAN-aware bridge per the referneces from @anav. On non-CRS Mikrotiks with a single switch chip it is possible to configure the chip to handle the VLAN tagging/untagging/filtering per the example in the Mikrotik help / wiki pages, but on devices with multiple switch chips there are issues as described in the link of my previous post.
