LLDP-MED Commands
The following are the LLDP-MED (Media Endpoint Discovery) commands.
The LLDP-MED commands are an extension of the set of LLDP TLV advertisement commands.
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.
Syntax
advertise med guest-voice {vlan-id layer2_priority DSCP_value} | {priority-
tagged number}
To return to the default, use the no advertise med guest-voice {vlan-id
layer2_priority DSCP_value} | {priority-tagged number} command.
Parameters
vlan-id Enter the VLAN ID. The range is from 1 to 4094.
layer2_priority Enter the Layer 2 priority. The range is from 0 to 7.
