• Organizationally-specific TLVs are optional in LLDP implementations and are defined and
encoded by individual organizations or vendors. These TLVs include support for, but are not
limited to, the IEEE 802.1 and 802.3 standards and the TIA-1057 standard.
Devices support the following Organizationally-specific TLVs:
• 802.1 organizationally-specific TLVs
• Port VLAN ID
• VLAN name TLV
• 802.3 organizationally-specific TLVs

Maximum frame size
Mandatory TLVs
When an LLDP agent transmits LLDP packets to other agents in the same 802 LAN segments, the
following mandatory TLVs are always included:
• Chassis ID
• Port ID
• Time to Live (TTL)
This section describes the above TLVs in detail.
Chassis ID
The Chassis ID identifies the device that sent the LLDP packets.
There are several ways in which a device may be identified. A chassis ID subtype, included in the
TLV and shown in Table 93, indicates how the device is being referenced in the Chassis ID field.
