LLDP-MED attributes advertised by the Brocade device
The LLDP-MED capabilities advertisement includes the following information:
• The supported LLDP-MED TLVs
• The device type (Network Connectivity device or Endpoint (Class 1, 2, or 3))
By default, LLDP-MED information is automatically advertised when LLDP-MED is enabled. To
disable this advertisement, enter a command such as the following.
Brocade(config)#no lldp advertise med-capabilities ports e 2/4 to 2/12
NOTE
Disabling the LLDP-MED capabilities TLV disables LLDP-MED.
To re-enable the LLDP-MED Capabilities TLV (and LLDP-MED) after it has been disabled, enter a
command such as the following.
Brocade(config)#lldp advertise med-capabilities ports e 2/4 to 2/12
The LLDP-MED capabilities advertisement will appear similar to the following on the remote device,
and in the CLI display output on the Brocade device (show lldp local-info).
Syntax: [no] lldp advertise med-capabilities ports ethernet <port-list> | all
For port-list , specify the ports in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• FESX compact switches – portnum
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually. Note that using the keyword all may cause undesirable
effects on some ports. For example, if you configure all ports to advertise their VLAN name, and the
configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
Extended power-via-MDI information
The extended Power-via-MDI TLV enables advanced power management between LLDP-MED
Endpoints and Network Connectivity Devices. This TLV provides significantly more information than
the 802.1AB Power-via-MDI TLV referenced in “Power-via-MDI” on page 473. For example, this TLV
enables an Endpoint to communicate a more precise required power level, thereby enabling the
device to allocate less power to the Endpoint, while making more power available to other ports.
The LLDP-MED Power-via-MDI TLV advertises an Endpoint IEEE 802.3af power-related information,
including the following:
• Power type – indicates whether the LLDP-MED device transmitting the LLPDU is a power
sourcing device or a powered device:
+ MED capabilities: capabilities, networkPolicy, location, extendedPSE
MED device type : Network Connectivity
