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.

S6000

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-taggednumber} command.

Parameters
