Why do we need voice VLAN?
A voice VLAN is a VLAN ( virtual local area network) that is specifically allocated for user’s voice data streams. It ensures the quality of voice traffic by improving the transmission priority of it when transmitted with other traffic.
What is the purpose of configuring VLANs?
VLANs allow network administrators to automatically limit access to a specified group of users by dividing workstations into different isolated LAN segments. When users move their workstations, administrators don’t need to reconfigure the network or change VLAN groups.
What is auxiliary VLAN?
The terms Voice VLAN or Auxiliary VLAN typically mean the same thing: They are a feature which allows an access port — which normally only accepts untagged traffic for a single VLAN — to also accept tagged traffic for a second VLAN.
What’s the difference between auxiliary VLAN and voice vlan?
The terms Voice VLAN or Auxiliary VLAN typically mean the same thing: They are a feature which allows an access port — which normally only accepts untagged traffic for a single VLAN — to also accept tagged traffic for a second VLAN.
Which is the voice vlan on the Switch port?
To enable this, we need to define two VLANs on the switch port – data VLAN and voice VLAN. Here is how we can do that: We’ve created two VLANs – VLAN 5 that will be used for data sent by the PC and VLAN 20 for IP phone’s voice traffic. We’ve then placed the port into both VLANs. The keyword voice indicates that the VLAN 20 will be a voice VLAN.
Can a VLAN carry traffic for multiple VLANs?
The other is to make use of the Auxiliary VLAN (or Voice VLAN) feature. Both solutions are discussed and compared below. Traditionally, if you want to carry traffic for multiple VLANs on a single port, you would configure a Trunk port. This would allow traffic for multiple VLANs to traverse the single link.
What are the VLANs on my IP phone?
The lines Access Mode VLAN: 5 (VLAN0005) and Voice VLAN: 20 indicate that the interface is indeed carrying traffic from both VLANs. Some IP phones can be automatically configured with appropriate VLANs using protocols such as LLDP or CDP.
