LLDP-MED Commands
The following are the LLDP-MED (Media Endpoint Discovery) commands.
Dell Networking OS LLDP-MED commands are an extension of the set of LLDP TLV advertisement
commands. The C-Series and S-Series support all commands.
The E-Series generally supports the commands. 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
Networking system is an LLDP-MED network connectivity device.
Regarding 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
advertise med guest-voice
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, configure the system.
