| Basic Administration Protocols

Link Layer Discovery Protocol

– 359 –

lldpStatsRemTableLastChangeTime to detect any lldpRemTablesChange

notification-events missed due to throttling or transmission loss.

Basic Optional TLVs – Configures basic information included in the

TLV field of advertised messages.

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 in the performance of

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.

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

"Displaying

System Information" on page 89

.

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 174

).
