Source note · Voice VLAN and LLDP-MED and CDP and PoE for IP phones
On Juniper EX Series switches, a voice VLAN lets an access port accept untagged data and tagged voice traffic in separate VLANs, and the switch uses LLDP-MED to send VoIP parameters to the phone so voice is tagged and prioritised at the source.
