Table 108: Voice VLAN Configuration Fields

Description
Click Enable or Disable to administratively turn the Voice VLAN feature on or off for
all ports.
Select the slot and port to configure this service on.
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 differently
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 priority.
• Untagged: The VoIP device sends untagged voice traffic.
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.
Indicates whether the voice VLAN is operational.
