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 (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 Power through MDI
