The Voice VLAN Port Setup Page contains the following fields:
■ Voice VLAN Port Mode — Specifies the Voice VLAN mode. The
possible field values are:
■
No Changes — Maintains the current Voice VLAN port/LAG
settings. This is the default value.
■
None — Indicates that the selected port/LAG will not be added to a
Voice VLAN.
■
Manual — Adding a selected port/LAG to a Voice VLAN.
■
Auto — Indicates that if traffic with an IP Phone MAC Address is
transmitted on the port/LAG, the port/LAG joins the Voice VLAN.
The port/LAG is aged out of the voice VLAN if the IP phone’s MAC
address (with an OUI prefix) is aged out and exceeds the defined
voice VLAN aging time. If the MAC Address of the IP phones OUI
was added manually to a port/LAG in the Voice VLAN, the user
cannot add it to the Voice VLAN in Auto mode, only in Manual
mode.

the Voice VLAN. Port security ensures that packets arriving with an
unrecognized MAC address are dropped. Port Security is only
applicable when Voice VLAN Port Mode is set to Auto.

settings.
■
Enable — Enables port security on the Voice VLAN.
■
