System Name TLV
For the Cisco Unified IP Conference Phone 8831 for Third-Party Call Control, the value is SEP+MAC
address.
Example: SEPAC44F211B1D0
The incoming LLDPDU, the System Name TLV, is ignored and not validated. Only one System Name
TLV is allowed for the outgoing and incoming LLDPDUs.
System Capabilities TLV
For the outgoing LLDPDU, in the System Capabilities TLV, the bit values for the 2 octet system
capabilities field should be set for Bit 2 (Bridge) and Bit 5 (Phone) for a phone with a PC port. If the
phone does not have a PC port, only Bit 5 should be set. The same system capability value should be set
for the enabled capability field. For the incoming LLDPDU, the System Capabilities TLV is ignored.
The TLV is not validated semantically against the MED device type. The System Capabilities TLV is
mandatory for outgoing LLDPDUs. Only one System Capabilities TLV is allowed.
Management Address TLV
The TLV identifies an address associated with the local LLDP agent (that may be used to reach higher
layer entities) to assist discovery by network management. The TLV allows the inclusion of both the
system interface number and an object identifier (OID) that are associated with this management
address, if either or both are known.
TLV information string length—This field contains the length (in octets) of all the fields in the TLV
information string.
Management address string length—This field contains the length (in octets) of the management address
subtype + management address fields.
System Description TLV
The TLV allows the network management to advertise the system's description.
TLV information string length—This field indicates the exact length (in octets) of the system
description.
System description—This field contains an alpha-numeric string that is the textual description of the
network entity. The system description includes the full name and version identification of the system's
hardware type, software operating system, and networking software. If implementations support IETF
RFC 3418, the sysDescr object should be used for this field.
IEEE 802.3 MAC/PHY Configuration/Status TLV
The TLV is not for auto-negotiation, but for troubleshooting purposes. For the incoming LLDPDU, the
TLV is ignored and not validated. For the outgoing LLDPDU, for the TLV, the octet value
auto-negotiation support/status should be:
Bit 0—Set to 1 to indicate the auto-negotiation support feature is supported.
•
Bit 1—Set to 1 to indicate auto-negotiation status is enabled.
•
Bit 2-7—Set to 0.
•
The bit values for the 2 octets PMD auto-negotiation advertised capability field should be set to:
Bit 13—10BASE-T half duplex mode
•
Bit 14—10BASE-T full duplex mode
•
Bit 11—100BASE-TX half duplex mode
•
