Media endpoint discovery LLDP-MED provides additional organizationally-specific TLVs to allow endpoint devices and network-connectivity devices to advertise their characteristics and configuration information. LLDP-MED devices are located at the IEEE 802 LAN network edge and participate in IP communication service using the LLDP-MED framework, such as IP phones and conference bridges. LLDP-MED network connectivity devices provide access to the IEEE 802-based LAN infrastructure for LLDP-MED endpoint devices, such as IP phones. An OS10 device acts as an LLDP-MED network connectivity device. LLDP-MED provides network connectivity devices to: • Manage inventory • Manage power over ethernet (PoE) • Identify physical location • Identify network policy NOTE: Only the Rx function is supported for managing PoE and identifying the physical location. LLDP-MED is designed for but not limited to VoIP endpoints. Network connectivity device OS10 acts as an LLDP-MED network-connectivity device (Type 4). Network connectivity devices transmit an LLDP-MED capability TLV to endpoint devices and stores information that endpoint devices advertise. 127/1 - LLDP-MED capabilities • • • If the transmitting device supports LLDP-MED What LLDP-MED TLVs are supported LLDP device class 127/2 - Network policy 127/3 - Local identification Application type, VLAN ID, L2 priority, and DSCP value.
