FTOS LLDP-MED (Media Endpoint Discovery) commands are an extension of the
set of LLDP TLV advertisement commands. The C-Series and S-Series support all
commands, as indicated by these symbols underneath the command headings:
c
s
The E-Series generally supports the commands, too, as indicated by the e symbol
under command headings. However, LLDP-MED commands are more useful on the
C-Series and the S50V model of the S-Series, because they support Power over
Ethernet (PoE) devices.
As defined by ANSI/TIA-1057, LLDP-MED provides organizationally specific
TLVs (Type Length Value), so that endpoint devices and network connectivity
devices can advertise their characteristics and configuration information. The
Organizational Unique Identifier (OUI) for the Telecommunications Industry
Association (TIA) is 00-12-BB.
• LLDP-MED Endpoint Device — any device that is on an IEEE 802 LAN
network edge, can communicate using IP, and uses the LLDP-MED framework.
• LLDP-MED Network Connectivity Device — any device that provides access
to an IEEE 802 LAN to an LLDP-MED endpoint device, and supports IEEE
802.1AB (LLDP) and TIA-1057 (LLDP-MED). The Dell Force10 system is an
LLDP-MED network connectivity device.
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

c e s
Configure the system to advertise a separate limited voice service for a guest user
with their own IP telephony handset or other appliances that support interactive voice
services.
