Hello Mikrotikers,
recently we aquired a CRS3xx-12-Port Switch (8 RJ45, 4 Combo SFP/RJ45) and the honour of dealing with it fell upon me. I put this in the Beginner Basics section because likely my problem is rooted in my ignorance of how the thing works exactly.
The following is my problem:
I initially set the Switch up to have both, trunk and access ports. Combo 1 is a trunk that connects to our other Switches (Cisco), there are 3 Trunks going into Servers with their own virtual Switches as well as 5 Access-Ports for different VLANs, all of this works fine. Now, wanted to add another server that’s supposed to be on an Access-Port for a certain VLAN and started reconfiguring one of the remaining Combo-Ports. Using WebFig and RouterOS, I couldn’t get it to work, though.
This is how I got the initial config working:
- Set up a Management-Bridge and gave it a IP-Address for Management and added ether9 (Management-Port) to it
- Removed the default bridge and set up a Bridge called vlan-bridge, enabled VLAN filtering
- Added all interfaces to the vlan-bridge
- Ran the command
/interface bridge vlan add vlan-ids=123 bridge=vlan-bridge tagged=combo1,ether1,ether2,ether3 untagged=ether6,ether7,ether8
repeatedly for each VLAN I wanted to add
This worked and I stopped there.
Now I want to add a VLAN as “untagged” to combo2. In WebFig, I go to bridge → VLAN → VLANID and add combo2 as untagged. This does nothing though.
After exporting the config, I found this:
/interface bridge port

add bridge=vlan-bridge tagged=combo1,ether1,ether2,ether3 untagged=combo2 \

The “/interface bridge vlan” part is what I’ve configured via console, except the vlan-bridge is always added as well. The “/interface bridge port” section must’ve been created through me adding the interfaces to the vlan-bridge in WebFig, although I don’t recall setting the pvid attribute (pvid stands for port vlan id?).
I wanted to try to add the pvid=212 to combo2, but with the “/interface bridge vlan add” command, it tells me that it already exists (obvious) and with “/interface bridge vlan set” it asks for a number and I do not know, what that means.
I’m also not even sure, this is the problem.
Can anyone help me out?
Thank you very much
