VLAN Settings
VLAN settings define the Ethernet frame priority and VLAN identification in accordance with IEEE 802.1p/Q
standards. Separate VLAN tags are assigned for the IP phone PC port and the LAN (voice) port. With a VLAN
ID assigned, only frames with the assigned ID are accepted, and all SIP and voice frames sent by the
FortiFone-450i/FortiFone-550i include the VLAN ID assigned to the LAN port. FortiVoice phone systems do not
support VLAN tagging so this should not be used with FortiVoice phone system deployments.
For proper operation, other network elements (LAN switches and default gateway) must support and be configured
with proper VLAN parameters.
VLAN settings are overwritten if CDP is enabled.
Changing the VLAN parameters requires a reboot of the IP phone. When you exit the menu, you will receive a reboot
notice. The phone must be rebooted to use the new values.
VLAN Priority (LAN)
The VLAN Priority (LAN) establishes the priority for Ethernet frames from the LAN port including signaling
and voice packets. Setting the VLAN ID to zero (0) disables VLAN framing and the IP phone uses only
standard Ethernet frames.
To assign VLAN Priority for the LAN (voice) port:
