LLDP-MED configuration
• Power class – Indicates the range of power that the connected powered device has negotiated
or requested.
NOTE
The power-via-MDI TLV described in this section applies to LLDP. There is also a power-via-MDI TLV
for LLDP-MED devices, which provides extensive POE information. Refer to “Extended power-via-MDI
information” on page 486.
To advertise the power-via-MDI information, enter a command such as the following.
Brocade(config)#lldp advertise power-via-mdi ports e 2/4 to 2/12
The power-via-MDI 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 power-via-mdi 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.
