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:
•
•
•
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

Brocade devices use chassis ID subtype 4, the base MAC address of the device. Other third party
devices may use a chassis ID subtype other than 4. The chassis ID will appear similar to the
following on the remote device, and in the CLI display output on the Brocade device (show lldp
local-info).
The chassis ID TLV is always the first TLV in the LLDPDU.
Port ID
The Port ID identifies the port from which LLDP packets were sent.
