CAUTION:
•
If an IP phone sends tagged voice traffic and its accessing port is configured with 802.1X authentication
and guest VLAN, assign different VLAN IDs for the voice VLAN, the PVID of the connecting port, and
the 802.1X guest VLAN.
• If an IP phone sends untagged voice traffic, to implement the voice VLAN feature, you must configure the
PVID of the IP phone’s accessing port as the voice VLAN. As a result, you cannot implement 802.1X
authentication.
