How do I set up voice and data VLANs?

How do I set up voice and data VLANs?

Create VLANs- Once trunk is configured we can create VLANs, as VTP is configured, so when VLANs are created on switch A they will automatically replicated to switch B. Assign ports to VLANs – Now we can assign ports to each VLAN. The ports are configured to support a voice VLAN of 10 and a data VLAN of 50.

What is the voice VLAN?

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.

How do I enable voice VLAN on a Cisco switch?

1. Switch# configure terminal.
2. Switch(config)# interface.
3. Switch(config-if)# trust-device.
4. • vlan-id—Configures the phone to forward. all voice traffic through the specified.
5. Switch(config-if)# end.
6. • show interfaces interface-id switchport.
7. Switch# copy running-config.
8. Switch> enable.

Is VTP on the new CCNA?

This topic is not included in the latest version of the CCNA exam (200-301). If you are studying for the exam feel free to skip this article. VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used by Cisco switches to exchange VLAN information.

What is Cisco Voice VLAN?

The voice VLAN feature enables access ports to carry IP voice traffic from an IP phone. The Cisco 7960 IP Phone is a configurable device, and you can configure it to forward traffic with an IEEE 802.1p priority. You can configure the switch to trust or override the traffic priority assigned by a Cisco IP Phone.

What is Cisco VTP?

VTP is CISCO proprietary protocol used to maintain consistency throughout the network or user can say that synchronizing the VLAN information in same VTP domain. VTP allows you to add, delete and rename VLANs which is then propagated to other switches in the VTP domain.

What is trunking in networking?

Networking. Trunking, a term frequently used in IT and telecommunications, refers to a network configuration that efficiently conveys data between multiple entities without using one-to-one links.

How does a Cisco IP Phone discover which VLAN to use for voice traffic?

We configured the switch but how does the IP phone know which VLANs to use? Cisco IP phones use CDP (Cisco Discovery Protocol) for this. The IP Phone will learn through CDP which VLANs it should use. Other IP phones sometimes use LLDP (Link Laye Discovery Protocol) for this.

Is VTP required?

There are some requirements for VTP to communicate VLAN information between switches. These are: The VTP version must be same on the switches user wants to configure. VTP domain name must be same on the switches.

What is VLAN in CCNA?

VLANs (Virtual LANs) are logical grouping of devices in the same broadcast domain. VLANs are usually configured on switches by placing some interfaces into one broadcast domain and some interfaces into another. Each VLAN acts as a subgroup of the switch ports in an Ethernet LAN.
