Hi!

I could do this setup on Cisco in seconds, but I fail on RouterOS.

I have a CRS328-24S+2Q+RM switch running RouterOS 6.45.9

I try to setup the following:

- Port sfp-sfpplus24 is my uplink port, tagged VLANs should include all in range 1000-1100
- Ports sfp-sfpplus1-2 are downlink trunk ports, tagged VLAN 1111 (just one for the beginning)
- Ports sfp-sfpplus3-4 are downlink trunk ports, tagged VLAN 1121 (just one for the beginning)
- Have one VLAN interface on VLAN 1111 with an IP address for SSH access to the switch
- Have no untagged VLANs at all (no default VLAN 1 on all ports)

This is my config so far: The IP address is not pingable and I don't know how to configure the VLAN range on sfp-sfpplus24...

Obviously CISCO is obsolete then! ;-)

Also, hot off the press.....

/interface vlan
add interface=bridge name=VLAN-1111 use-service-tag=yes vlan-id=1111

The setting I highlited is toggle between using 802.1q ("usual" VLAN) and 802.1ad ("QinQ" VLAN). Most users want to use 802.1q tags and corresponding setting is use-service-tag=no (which is default and thus not show in textual exports).

Another thing is (missing) bridge setting of vlan-filtering=yes under /interface bridge. Without it, bridge won't do anything about VLAN tags and will behave as dumb switch ... in your particular case (with all ports trunk) it wouldn't actually make any difference apart from the fact that VLANs would "bleed" all over the place. OTOH if you wanted to use access port or hybrid port (in Cisco world that's trunk with native VLAN), it wouldn't work as ports would not tag/untag frames when passing it.

Thank you!

Works fine!
