Configuring the Switch
• TLV Type – Configures the information included in the TLV field of advertised
messages.
- 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 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 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.
- 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 3-12.
- 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.
• MED TLV Type – Configures the information included in the MED TLV field of
advertised messages.
- Port Capabilities – This option advertises LLDP-MED TLV capabilities, allowing
Media Endpoint and Connectivity Devices to efficiently discover which
LLDP-MED related TLVs are supported on the switch.
- Network Policy – This option advertises network policy configuration
information, aiding in the discovery and diagnosis of VLAN configuration
mismatches on a port. Improper network policy configurations frequently result
in voice quality degradation or complete service disruption.
- Location – This option advertises location identification details.
- Extended Power – This option advertises extended Power-over-Ethernet
capability details, such as power availability from the switch, and power state of
the switch, including whether the switch is operating from primary or backup
