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 ).
Chassis ID (MAC address): 0000.0033.e2c0
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.
There are several ways in which a port may be identified, as shown in the following table. A port ID
subtype, included in the TLV, indicates how the port is being referenced in the Port ID field.
