Can you have 2 voice Vlans?

Can you have 2 voice Vlans?

Re: 2 voice vlans just use the voice command under the 2 vlans. For this, the switch simply checks the tagged vlan membership of the port, so if you only allow the vlan you want on these ports it should work. Sample config, assumes 1 switch with 48 ports, assume 1 user data vlan (untagged) and 2 voice vlans.

What are the 3 types of Vlans?

Types of VLAN

• Management VLAN.
• Data VLAN.
• Voice VLAN.
• Default VLAN.
• Native VLAN.

What is Auto Voice VLAN?

Auto Voice VLAN is responsible to maintain the voice VLAN, but depends on Auto Smartport to maintain the voice VLAN port memberships. Auto Voice VLAN performs the following functions when it is in operation: • It discovers voice VLAN information in CDP advertisements from directly connected neighbor devices.

What is the difference between voice VLAN and data VLAN?

The LAN used for voice traffic from the IP phone is called the voice VLAN and the VLAN used for data is called the data or access VLAN.

How is the native VLAN used in voice over IP?

The voice VLAN feature enables access ports to carry IP voice traffic from an IP phone. When the switch is connected to a Cisco 7960 IP Phone, the phone sends voice traffic with Layer 3 IP precedence and Layer 2 class of service (CoS) values, which are both set to 5 by default.

What is l2 and L3 VLAN?

I answered them, Layer 2 VLAN is a single broadcast domain. It works on layer 2 (Datalink Layer). They can communicate only within it. And L3 VLAN is an Interface, that works on Network Layer. In order to do inter VLAN routing/ communication we need L3 interface (SVI).

Why is VLAN 1 the default VLAN?

Having all the switch ports participate in the default VLAN makes them all part of the same broadcast domain. This allows any device connected to any switch port to communicate with other devices on other switch ports. The default VLAN for Cisco switches is VLAN 1.

How do I add a voice VLAN?

1. How to Configure Voice VLAN?

1. Create a VLAN on the switch and add interfaces to the VLAN to implement Layer 2 interworking.
2. Configure the OUI to match the source MAC address of the received packet.
3. Configure the voice VLAN function on the interface.

What is the purpose of Lldp?

LLDP is a neighbor discovery protocol that is used for network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other.

Is voice VLAN tagged or untagged?

The voice traffic is an 802.1q-tagged packet with a VLAN ID (that might or might not be 0) and an 802.1p (3-bit layer 2 COS) with a specific value (typically 5 is assigned for voice traffic). Data traffic is always untagged.

What is the voice VLAN used for?

What is native VLAN?

Native VLAN: The native VLAN is the one into which untagged traffic will be put when it’s received on a trunk port. This makes it possible for your VLAN to support legacy devices or devices that don’t tag their traffic like some wireless access points and simply network attached devices.
