Sorry for posting a question that has come up on a number of other threads, but looking for clarity on the latest status.
Elsewhere, I use HP Procurve 2600 series switches which can mix both untagged and tagged VLANs on the same port, no issue.
I bought one of the RouterBOARD SwOS products assuming it would be capable of the same, but it appears that you cannot tag VLANs on an access port and vice-versa.
What I'm looking for is, for example
Port 1 untagged vlan 10 (client PC)
Port 2 untagged vlan 10 (client PC)
Port 3 untagged vlan 10 tagged vlans 20 40 60 80 100 (cisco aironet 1231, native vlan 10)
Port 4 untagged vlan 10 tagged vlan 20 (mitel 5312 phone - voice tagged vlan 20, pc port using vlan 10)
Port 5 tagged vlans 10 20 40 60 80 100 (trunk to RB750)
Ports 1, 2, 5 I can configure no issue.
Unable to get ports 3 & 4 working as required.
