TLV support
This section lists the LLDP and LLDP-MED TLV support.

LLDP TLVs

There are two types of LLDP TLVs, as specified in the IEEE 802.3AB standard:
•Basic management TLVs consist of both optional general system information TLVs as well as
mandatory TLVs.
Mandatory TLVs cannot be manually configured. They are always the first three TLVs in the
LLDPDU, and are part of the packet header.
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 (mandator y)
•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
Power through MDI
