With regard to connected endpoint devices, LLDP-MED provides network connectivity devices with the
ability to:
•
manage inventory
•
manage Power over Ethernet (PoE)
•
identify physical location
•
identify network policy
LLDP-MED is designed for, but not limited to, VoIP endpoints.
TIA Organizationally Specific TLVs
The Dell Force10 system is an LLDP-MED Network Connectivity Device (Device Type 4). Network
connectivity devices are responsible for:
•
transmitting an LLDP-MED capabilities TLV to endpoint devices
•
storing the information that endpoint devices advertise

Description
Indicates:
•
whether the transmitting device supports LLDP-MED
•
what LLDP-MED TLVs it supports
•
LLDP device class
Indicates the application type, VLAN ID, Layer 2 Priority, and
DSCP value
Indicates the physical location of the device expressed in one of
three possible formats:
•
Coordinate Based LCI
•
Civic Address LCI
•
Emergency Call Services ELIN
Indicates power requirements, priority, and power status
Implementation of this set of TLVs is optional in LLDP-MED
devices. None or all TLVs must be supported. FTOS does not
currently support these TLVs.
