The LLDP-MED (Link Layer Discovery Protocol for Media Endpoint Devices) method differs from the Voice VLAN method in that it allows the switch to configure specific parameters of directly connected LLDP-MED supported IP phones, such as their VLAN and priority. Some IP phones only allow certain parameters to be configured using LLDP-MED. This method is accomplished by configuring the LLDP-MED Network Policy of the switch. On the other hand, the Voice VLAN method categorizes packets based on source MAC addresses using a configured OUI.
