Voice over IP with Private VLANs

[Gunter Vlemmix]

I have today private vlans implemented in my network, but I want to use Voip in the near future.

Can I still use the private vlans when my PC is connected behind the IP phone?

What is the best implementation if you have today Private Vlans and want to use tomorrow VoIP?

Here's how I'm doing it. On an interface where the private VLAN (i.e., the PC) is on VLAN3 and the VoIP VLAN is VLAN2:

interface FastEthernet0/17

switchport trunk encapsulation dot1q

switchport mode trunk

switchport trunk native vlan 3

switchport voice vlan 2

switchport priority extend cos 0

All untagged packets will be asigned to VLAN3, but the Cisco IP phone will have its packets tagged for VLAN2.
