• 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:
• ‐
Port VLAN ID
VLAN name TLV
• ‐
MAC/PHY configuration/status
Power through MDI
Link aggregation
Maximum frame size
LLDP-MED TLVs
Brocade devices honor and send the following LLDP-MED TLVs, as defined in the TIA-1057 standard:
• LLDP-MED capabilities
• Network policy
• Location identification
• Extended power-via-MDI
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 the following table, indicates how the device is being referenced in the Chassis ID field.
