Link Layer Discovery Protocol
– 342 –
◆ 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. (Default: Enabled)
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.
(Default: Enabled)
■
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. (Default: Enabled)
■
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. (Default: Enabled)
■
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 64 . (Default: Enabled)
◆
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 164 ). (Default: Enabled)
