Seperate VLAN PC port vs Phone

I have looked around the FAQ and searched and read several post that seemed similar to what i was looking for, but dont seem to address the question I have. My apologies up front if I have missed it. 


We have setup a new hybrid Skype for Business to test out the new PTSN calling. 


We ordered a Polycom device to test with 



Phone Model VVX 601
Part Number 3111-48600-001 Rev:A
UC Software Version
Updater Version



I have been trying to Get BToE working, and I get the device connected with my pc just fine. The only issue I have is that I dont really want to have my PC on the same VLAN as the voice traffic.


DHCP will issue the address in the same /24 scope to both devices and I do not see a way configure the phone to have both tagged to run them into a trunk port so DHCP would know issue an address on the appropriate vlan. The things that i have read address the PC port very little, so maybe i'm just not searching for the right term. 


Currently I use vlan5 for data and vlan10 for voice.


Could you comment if the above is possible or direct me to documentation that would explain how to do this. I am more than happy to do the leg work and read. I thank you for any assistance you could provide in advance.

Hello gstopjturner,

welcome to the Polycom Community.

I usually would expect a PC to use a different VLAN as long as you can route the connectivity between the two.


The BToE application on the phone itself will send a broadcast on the PC port

Re: Seperate VLAN PC port vs Phone

Not sure what type of switching environment you're connecting the phone to, but in a Cisco environment you would configure the switchport as follows to accomplish your goal:


switchport voice vlan 10

switchport access vlan 5


Configure the phone for VLAN ID 10


The PC behind the phone will be on VLAN 5.


Other vendors have different syntax, but the theory is the same:  The switchport needs to be a trunk, tagging VLAN 10, and passing VLAN 5 untagged.
