Just curious, if I have my Polycom IP 550 phone VLAN tag 30, will the packets I send from my PC(on the PC port of the phone) have the same VLAN tag? THe PC is sending untagged packets.

The switch on the Polycom will pass the frames on unchanged, so if they
are untagged from the PC they will remain that way.

According to this --

http://www.polycom.com/common/documents/whitepapers/
vlans_and_polycom_soundpoint_ip_desktop_ip_telephones.pdf

"If a PC is connected to the phone, all packets generated by the PC will
be passed through unmodified, regardless of the presence of an 802.1q/p
tag or its contents. Since PCs do not typically tag frames, this means
they will be on the native VLAN. "

This is the whole point behind using VLAN on the phone. Tagged VLAN
for your phone with QoS configured accordingly on your switch and
untagged VLAN for your PC, both on the same wire. This way you can
always guarantee enough bandwidth for your VoIP packets.

Thanks,
Wojtek
