Link Layer Discovery Protocol

- System Description – The system description is taken from the sysDescr

object in RFC 3418, which includes the full name and version identification of the
system's hardware type, software operating system, and networking software.

- Management Address – The management address protocol packet includes

the IPv4 address of the switch. If no management address is available, the
address should be the MAC address for the CPU or for the port sending this
advertisement.
The management address TLV may also include information about the specific
interface associated with this address, and an object identifier indicating the type
of hardware component or protocol entity associated with this address. The
interface number and OID are included to assist SNMP applications perform
network discovery by indicating enterprise specific or other starting points for the
search, such as the Interface or Entity MIB.
Since there are typically a number of different addresses associated with a
Layer 3 device, an individual LLDP PDU may contain more than one
management address TLV.
Every management address TLV that reports an address that is accessible on a
port and protocol VLAN through the particular port should be accompanied by a
port and protocol VLAN TLV that indicates the VLAN identifier (VID) associated
with the management address reported by this TLV.

- System Name – The system name is taken from the sysName object in

RFC 3418, which contains the system’s administratively assigned name. To
configure the system name, see “Displaying System Information” on page 4-1.

- System Capabilities – The system capabilities identifies the primary function(s)

of the system and whether or not these primary functions are enabled. The
information advertised by this TLV is described in IEEE 802.1AB.

Web – Click LLDP, Port/Trunk Configuration. Set the LLDP transmit/receive mode,
specify whether or not to send SNMP trap messages, and select the information to
advertise in LLDP messages. Then click Apply.
