Link Layer Discovery Protocol
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.
Port Description – The port description is taken from the ifDescr
■
object in RFC 2863, which includes information about the
manufacturer, the product name, and the version of the interface
hardware/software.
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.
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.
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

802.1 Organizationally Specific TLVs – Configures IEEE 802.1
information included in the TLV field of advertised messages.
Protocol Identity – The protocols that are accessible through this
■
interface (see
"Protocol VLANs" on page
VLAN ID – The port's default VLAN identifier (PVID) indicates the
■
VLAN with which untagged or priority-tagged frames are associated
(see
"IEEE 802.1Q VLANs" on page
VLAN Name – The name of all VLANs to which this interface has
■
been assigned (see
Port and Protocol VLAN ID – The port-based protocol VLANs
■
configured on this interface (see
802.3 Organizationally Specific TLVs – Configures IEEE 802.3
◆
information included in the TLV field of advertised messages.
Link Aggregation – The link aggregation capabilities, aggregation
■
status of the link, and the IEEE 802.3 aggregated port identifier if
this interface is currently a link aggregation member.
