How to create a hybrid vlan port on the CRS-125

RouterOS Beginner Basics

Hi, I’m new to Mikrotik and I didn’t find any clear information on how to configure an hybrid port (Data vlan untagged, Voice VLAN tagged) on the Cloud router switch. If i’m looking at the example http://wiki.mikrotik.com/wiki/Manual:CRS_examples I would like to mix Example 2 with the InterVLAN routing, is it possible? Thank you.

Here an example of what I want to do.

To run both tagged and “untagged” on the same port, you need to set up ingress vlan translation to tag the untagged traffic from the node (i.e. translate vlan 0 to any arbitrary VLAN id). You can then also set up egress vlan translation to untag that same VLAN. Finally, configure the tagged VLANs to be valid on that port.

Remember, from the switch’s perspective, ALL traffic should be tagged. You just need to create the rules so that the right traffic is either tagged or untagged as it leaves the switch.

This what I did, untagged packet are working fine but not the tagged ones. I tagged my vlan 80 on the switch1-cpu like in the example for the intervlan routing so cannot for example add ether5 t egress-vlan-tag cause switch1-cpu is already tag. My phone packet are coming tagged vlan 80 on port ether5 so I don’t need to translate them on ingress neither on egress?

No one have ever programmed vlan(tagged / untagged) on these switches ?

Using WebFig…

Under “Switch > VLAN” on the VLAN tab, add the VLAN ID’s to the desired ports (e.g. add VLAN 80 to port 15 or whichever port you want, and also add VLAN 100 to port 15…I would avoid using VLAN 1 for untagged traffic).

Now go to the VLAN Tagging tab. This is where you set up egress VLAN tagging. Set port 15 to tag VLAN 80.

Now go to the In. VLAN Tran. tab. Configure port 15 to do ingress translation from VLAN 1 to VLAN 100 (this is why you don’t use VLAN 1 for normal traffic). You’ll use the “Customer VID” field and the “New Customer VID” field.

In my experience, you don’t even need to bother with setting up the Egress VLAN translation to reverse the VLAN 100 back to VLAN 1 on the port.

Default untagged VLAN on Mikrotik it’s not the VID 0?
