Inventory TLV The majority of IP Phones lack support of management protocols such as SNMP, so 
LLDP-MED inventory TLVs are used to provide their inventory information to the Network 
Connectivity Devices such as the Switch. The Inventory TLV may contain the following 
information.
• Hardware Revision 
•Software Revision 
•Firmware Revision 
•Model Name 
• Manufacturer 
• Serial Number 
•Asset ID 
Extended 
Power via MDI 
TLV
Extended Power Via MDI Discovery enables detailed power information to be advertised 
by Media Endpoints, such as IP phones and Network Connectivity Devices such as the 
Switch.
• Power Type - whether it is currently operating from primary power or is on backup 
power (backup power may indicate to the Endpoint Device that it should move to a 
power conservation mode).
• Power Source - whether or not the Endpoint is currently operating from an external 
power source.
• Power Priority - the Endpoint Device’s power priority (which the Network Connectivity 
Device may use to prioritize which devices will remain in service during power 
shortages)
• Power Value -  power requirement, in fractions of Watts, in current configuration
