VLAN CONFIGURATION
Hi Experts!
I am setting a new VoIP infrastructure and in the process deploying new firewalls and switches. I would like to utilize vlans to logically separate the voice and data but most of our ports are piggybacked (phone and computer are connected to the same jack and switch-port). I plan on using LLDP for the voice so no issue there, but my question is - how does the switch-port distinguish the data? Is it simply process of elimination (given the voice is using LLDP)? I'm guessing not, but was hoping someone could explain it in a little more depth. I'm trying to keep it as simple as possible, so the vlan config will be layer 2, as will the QoS (or I guess more appropriately CoS given layer 2 right?). So basically I'm going to use a layer 2 switch behind the firewall and create vlan 10 & vlan 20 (voice & data respectively) on the firewall, and trunk the switch.
I hope this is enough information to answer my question, but if not let me know and I will provide whatever details necessary.
Thanks.

I understand what you are saying about the switchport being a member of both VLANs (much like trunk mode). The thing I'm not understanding is how I would define additional VLANs (for example a printer VLAN), if we're simply saying that untagged packets represent data and tagged packets represent voice. This would also mean that a soft-phone running on a computer (or basically anything that isn't voice) would also be treated as data correct?
