LLDP-MED attributes advertised by the Brocade device
LLDP-MED attributes are only advertised on a port if LLDP-MED is enabled (which is done by enabling
the LLDP-MED capabilities TLV), the port operating mode is receive and transmit (the default), and the
port has received an LLDP-MED advertisement from an Endpoint. By default, the Brocade device will
automatically advertise the following LLDP-MED attributes when the above criteria are met:
• LLDP-MED capabilities
• Location ID
• Network policy
• Power-via-MDI information
NOTE
Although the Location ID and Network policy attributes are automatically advertised, they will have no
effect until they are actually defined.
LLDP-MED capabilities
When enabled, LLDP-MED is enabled, and the LLDP-MED capabilities TLV is sent whenever any other
LLDP-MED TLV is sent. When disabled, LLDP-MED is disabled and no LLDP-MED TLVs are sent.
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.
device(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.
device(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 ).

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
on page 185. For example, this TLV
