VLAN config

Hi,
I’m looking for assistance in setting up a vlan network between a mikrotik CCr and a Mikrotik CCS.

I have a cloud core router installed at site A with a licensed link to site B where I have a cloud core switch installed.
I have traffic flowing through ethernet port 2 of the CCR to port 2 on the CCS with devices connected to ports 3,4 and 5.
I want to send separate internal traffic through port 5 on the CCR to port 8 on the CCS via a vlan.
I would appreciate any assistance in creating the above.

Regards

Adam

please explain the ports and respective vlans and if are tagged or untagged
