Voice VLAN

You can enhance your Voice over IP (VoIP) service by configuring ports to carry IP voice traffic from IP phones on a specific VLAN. Voice VLAN provides QoS to VoIP, ensuring that the quality of the call does not deteriorate if the IP traffic is received erratically or unevenly.

To activate Voice VLAN

  1. Navigate to Policies > Policy Hierarchy > Switch Policy.
  2. Select the System tab and scroll down to the Voice VLAN section.
  3. Enable the toggle bar, Voice VLAN.
  4. Select the Mode. The options are Auto and OUI.
  5. Specify the Voice VLAN ID. The range is from 1 to 4094. Only one Voice VLAN is supported on the Switch.
  6. Select the QoS Priority. Options are from 1 to 7. Priority Tagging places a priority tag in a specified frame placing it in a priority queue once received and enabling it to be prioritized ahead of other frames.
  7. Specify the DSCP. Differentiated Services Code Point (DSCP) defines a value from 0 to 63 that maps to a certain traffic classification. The range is from 0-63.
  8. If you select OUI mode, you can select the Enable Remark Cos/802.1p option. This defines a service priority for traffic on the Voice VLAN. The priority of any received VoIP packet is overwritten with the new priority when the Voice VLAN feature is active on a port.
  9. Specify the Remark Cos/802.1p values. The range is from 0 to 7.
  10. Specify the Aging Time in minutes. The range is from 30 to 65535.
  11. Specify the OUI Address and Description.
