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 dened by ANSI/TIA-1057, LLDP-MED provides organizationally specic TLVs (Type Length Value), so that endpoint devices and
network connectivity devices can advertise their characteristics and conguration information. The Organizational Unique Identier
(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, congure 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.
DSCP_value Enter the DSCP value. The range is from 0 to 63.
