You are deploying IP phones in your enterprise networks.

To provide IP phones with geographic location details (such as civic addresses or coordinates) automatically, Juniper EX Series switches utilize theLLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery)protocol.

VoIP Specifics:While standard LLDP (C) is for general device discovery,LLDP-MEDis an enhancement specifically designed for network-to-endpoint communication for VoIP devices.

Location Identification:LLDP-MED supportsLocation Identification TLVs(Type-Length-Values). These allow a switch to push geographic or civic location data to an IP phone, which is critical for E911 services and asset tracking.

Junos Implementation:On EX Series switches, this is typically configured under protocols lldp-med to ensure the switch advertises the necessary location information to connected endpoints.
