• Power Sourcing Equipment (PSE) power pair - indicates which pair of wires is in use and whether
the pair selection can be controlled. The Brocade implementation always uses pair A, and cannot
be controlled.
• 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 207.
To advertise the power-via-MDI information, enter a command such as the following.
device(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 ).
+ 802.3 Power via MDI: PSE port, power enabled, class 0
Power Pair : A (not controllable)

LLDP-MED configuration
This section provides the details for configuring LLDP-MED.
The following table lists the global and interface-level tasks and the default behavior/value for each
task.

Changing the Fast Start Repeat Count The system automatically sets the fast start repeat count to 3 when a
Network Connectivity Device receives an LLDP packet from an
Endpoint that is newly connected to the network.
NOTE
The LLDP-MED fast start mechanism is only intended to run on links
between Network Connectivity devices and Endpoint devices. It does
not apply to links between LAN infrastructure elements, including
between Network Connectivity devices, or to other types of links.
