Tagged and untagged traffic in same VLAN on same port

[jeronimo]

Hey,

Is it possible to have tagged and untagged egress on a single port and in the same VLAN?
Apparently not. (The switch sets either tagged or untagged egress.)
Is there a workaround? (like assigning the VLAN once untagged and once tagged to a fixed MAC address or so maybe)

The use case is this:
Usually we have VoIP-phones with PCs behind them connected. Phones and PCs are in different VLANs. Standard stuff.
Now there is an exception where there is a PC running some VoIP-admin thingy which (theoretically at least) belongs nicely into the same VLAN than the phones. But in this scenario it seems we will not be able to cascade phone and PC.....

Any thoughts?

Thanks,

So you want the PC to be in both VLANs at the same time? This is not possible as long as the PC does not support VLAN tagging. You should consider using a dedicated management PC or upgrading it to a model which supports VLAN tagging.

that will not either allow to get connectivity to both vlans from a single pc at the same time

What about dynamic VLAN assignment?

[Nick_Yakimenko]

switch side:
vlan10 voip
vlan20 ethernet
one port on a switch
different subnets on each vlan

how should he get connectivity on both networks/vlans at the same time?

But then you can assign that VLAN untagged to that port. Am I missing something here?
