Voice VLAN Configuration
The
Voice VLAN Configuration
page contains the following fields:
•
Voice VLAN Admin Mode
— Click Enable or Disable to administratively turn the Voice
VLAN feature on or off for all ports.
•
Unit/Slot/Port
— Specifies
Select the stack unit, slot, and port to configure this service on.
•
Voice VLAN Interface Mode
— Select one of the following interface modes:
-
Disable
: The voice VLAN service is disabled on this interface. Note that the Admin
mode field takes precedence; i.e., if a particular interface is enabled, but the Admin
Mode field is set to Disabled, then the service will not be operational.
-
None
: The voice VLAN service is disabled on this interface; however, unlike Disable
mode, the CoS override feature is still operational on the port.
-
VLAN ID
: The voice VLAN packets are uniquely identified by a number you assign.
All voice traffic carries this VLAN ID to distinguish it from other data traffic which is
assigned the port’s default VLAN ID. However, voice traffic is not prioritized differ-
ently than other traffic.
-
dot1p
: This parameter is set by the VoIP device for all voice traffic to distinguish
voice data from other traffic. All other traffic is assigned the port’s default VLAN ID.
This feature may not be supported by all hardware configurations.
-
Untagged
: Configures the phone to send untagged voice traffic.
•
CoS Override Mode
— Overrides the 802.1p class-of-service (CoS) value for all data
(non-voice) packets arriving at the port. Thus any rogue client that is also connected to the
voice VLAN port cannot deteriorate the voice traffic.
•
Operational State
— Indicates whether the voice VLAN is operational.
If you make any changes, click
