- 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 so ftware.
- Management Address – The managem ent addres s protocol packe t includes
the IPv4 address of the switch. If no m anageme nt addre ss is availabl e, 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 specifi c
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 as sociated 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 s hou ld be ac com pan ie d b y 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 obje ct 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 en abled. The
information advertised by this TLV is described in IEEE 802.1AB.
