Configuring LLDP and LLDP-MED
Table 120 lists the individual Dell PowerConnect switches and the Link Layer Discovery Protocol
(LLDP) features they support.
This chapter describes how to configure the following protocols:
Link layer discovery protocol (LLDP) – The Layer 2 network discovery protocol described in the IEEE
802.1AB standard, Station and Media Access Control Connectivity Discovery. This protocol
enables a station to advertise its capabilities to, and to discover, other LLDP-enabled stations in the
same 802 LAN segments.
LLDP media endpoint devices (LLDP-MED) – The Layer 2 network discovery protocol extension
described in the ANSI/TIA-1057 standard, LLDP for Media Endpoint Devices. This protocol enables
a switch to configure and manage connected Media Endpoint devices that need to send media
streams across the network (e.g., IP telephones and security cameras).
LLDP enables network discovery between Network Connectivity devices (such as switches),
whereas LLDP-MED enables network discovery at the edge of the network, between Network
Connectivity devices and media Endpoint devices (such as IP phones).
