Port Description TLV
For the outgoing LLDPDU, in the Port Description TLV, the value for the port
description is the same as "Port ID TLV" for CDP. The incoming LLDPDU, the Port
Description TLV, is ignored and not validated. Only one Port Description TLV is
allowed for outgoing and incoming LLDPDUs.
System Name TLV
For the outgoing LLDPDU, in the System Name TLV, the value is the same as
'Platform TLV" for CDP. For the Cisco SPA525G2, the name is "SPA525G2." 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.
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
• Bit 10—100BASE-TX full duplex mode
• Bit 15—Unknown
