Indicates the power profile which is currently associated
with this port. This object references the corresponding
h3cPseProfileIndex object in the power profiles table. A
value of zero is a special case and indicates that no
power profile is currently associated with this port. When
h3cPseProfileIndex is set to an index of existent profile,
pethPsePortPowerPairs, pethPsePortPowerPriority,
pethPsePortAdminEnable and h3cPsePortPowerLimit will be
set to the same as corresponding value. PethPsePortPowerPairs,
pethPsePortPowerPriority and pethPsePortAdminEnable are objects
of rfc3621-Power-Ethernet.mib.
