Overview

If an IP phone sends packets with VLAN 0 or untagged packets, the switch can identify the OUI of the untagged packet from the IP phone. Then the switch adds the voice VLAN ID to the packet and increases the priority of the packet based on the voice VLAN ID.

For applicable IP phones, see List of IP Phone Models That Can Be Connected to Switches.

Configuration Notes

This example applies to all models of V200R003C00 and later versions.
For the fixed device (S5720EI, S6720EI, S6720S-EI), and modular device (excluding X series cards), in V200R010 and later versions, run the voice-vlan vlan-id enable include-tag0 command to enable the switch to identify packets with tag 0 as voice packets and adds the voice VLAN ID to packets.
When IP phones are connected in Voice-VLAN include-untagged mode, disable LLDP on the interface or run the undo lldp tlv-enable med-tlv network-policy command to disable the switch and IP phones from advertising the VLAN configuration. Otherwise, the switch allocates the voice VLAN ID to IP phones through LLDP. Then IP phones send tagged packets to the switch, whereas the switch forwards untagged packets to IP phones. As a result, IP phones cannot go online.
If Mitel 5212 phones cannot go online, rectify the fault by referring to Cause 6: Customized Options Are Not Configured for a Switch Functioning as the DHCP Server. As a Result, Mitel 5212 Phones Fail to Go Online.

Networking Requirements

In Figure 1-6, to save investment costs, the customer requires that IP phones connect to the network through VoIP. IP phones cannot obtain voice VLAN IDs and can send only untagged voice packets. The network plan should meet the following requirements:

The priority of voice packets is increased to ensure communication quality of IP phones.
Voice packets are transmitted in VLAN 100.
IP addresses of IP phones are on a different network segment from that of the DHCP server, and DHCP snooping is configured to improve network security.
IP phones need to connect to switches through MAC address authentication.

Figure 1-6 Networking diagram of connecting switches to IP phones through the OUI-based voice VLAN

Configuration Roadmap

To implement interoperation between switches and IP phones through the OUI-based voice VLAN, you need to apply for IP addresses for IP phones, bring IP phones online after authentication, and conduct communication normally. Figure 1-7 shows the process for interoperation between switches and IP phones through the OUI-based voice VLAN.

The operations of applying for IP addresses and enabling IP phones to go online after authentication can be performed simultaneously.

Figure 1-7 Process for interoperation between switches and IP phones through the OUI-based voice VLAN

According to the preceding process, the configuration roadmap is as follows:

Configure OUI-based voice VLANs, assign VLANs to IP phones, and increase the priority.
Configure the DHCP relay function and DHCP server to allocate IP addresses to IP phones.
Configure the authentication server and enable IP phones to go online after authentication.
