General system information TLVs are optional in LLDP implementations and are defined by the
Network Administrator.
Brocade devices support the following Basic Management TLVs:
• Chassis ID (mandatory)
• Port ID (mandatory)
• Time to Live (mandatory)
• Port description
• System name
• System description
• System capabilities
• Management address
• End of LLDPDU
• 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.
Brocade devices support the following Organizationally-specific TLVs:
• 802.1 organizationally-specific TLVs
• Port VLAN ID
• VLAN name TLV
• 802.3 organizationally-specific TLVs
• MAC/PHY configuration/status
• Link aggregation
• 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)
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 20 , indicates how the device is being referenced in the Chassis ID field.
