Switch based LLDP-MED or MAC OUI to know is the preferred method to set a phone into a specific VLAN.

You are watching: What vendor neutral protocol implements support for vlan tagging

On bootup, the switch have the right to identify the an equipment is a phone making use of LLDP-MED and also can location the device into the exactly VLAN automatically. This is periodically referred to together a Voice VLAN in move configurations. Every switch merchant implements this differently, but nearly all managed switches have this feature in one type or another.

Some switches will use actual LLDP-MED to recognize a connected maker as a phone, if some frequently times lower expense switches will just use the MAC deal with OUI.

General an approach For Configuration

Create a brand-new VLAN committed for voice trafficTag brand-new voice website traffic VLAN to ports phones will connect toIdentify the new VLAN as a "voice" or "phone" type VLANSetup classification an approach for devices that room to be considered a phoneVerify phone call receives DHCP ~ above voice VLAN from voice scope, and also calls space able come complete.

In either case, the basic setup is a default/native/untagged vlan ~ above an interface for the data traffic, and also a 2nd tagged VLAN determined as the voice VLAN on the exact same interface. When the call boots up, the switch identifies the device as a phone, and also associates the phones traffic v the tagged voice VLAN.

There room other methods that require complicated DHCP setups, or statically assigning the VLAN identifier right into each phone individually. Neither room supported by stayinfiji.com.



While complicated double-fetch DHCP approaches are not required when the network switches renders the determination as to which VLAN a an equipment belongs, a DHCP server or Relay is still forced on the voice VLAN so that phones are able to receive an IP address.

MAC resolve OUI

Short for Organizational Unique Identifier, the first 24 bits that a MAC attend to for a network-connected device, which show the specific seller for the device. The IEEE assigns OUIs to vendors. (The critical 24 bits that the MAC attend to are the device"s distinct serial number, assigned come the device by the manufacturer.)

The OUI sometimes is referred to as the Vendor ID.

TheLink Layer discovery Protocol(LLDP) is a vendor-neutrallink layerprotocol offered by network devices for heralding their identity, capabilities, and neighbors top top anIEEE 802local area network, principallywired Ethernet.The protocol is formally described by the IEEE asStation and Media access Control Connectivity Discoveryspecified inIEEE 802.1ABandIEEE 802.3 ar 6 clause 79.

LLDP performs functions similar to severalproprietary protocols, together asCisco discovery Protocol (CDP),Foundry exploration Protocol,Nortel exploration ProtocolandLink great Topology Discovery.

Media endpoint discovery extension

Media Endpoint Discoveryis an enhancement of LLDP, well-known asLLDP-MED, that provides the following facilities:

Auto-discovery the LAN policies (such together VLAN,Layer 2 PriorityandDifferentiated services(Diffserv) settings) enablingplug and also playnetworking.Extended and automated power administration ofPower end Ethernet(PoE) end points.Inventory management, enabling network administrators come track their network devices, and determine their characteristics (manufacturer, software and hardware versions, serial or asset number).

The LLDP-MED protocol extension was officially approved and published as the standard ANSI/TIA-1057 through theTelecommunications industry Association(TIA) in April 2006.
