Power Over Ethernet
unconfig inline-power disconnect-precedence [lowest-priority |
deny-port] Returns the
disconnect-precedence
to
the default state of
deny-port
. When the
power drain exceeds the available power
budget, due to a rise in power
consumption after power is allocated to the
ports, the PoE controller disconnects one
of the ports to prevent overload on the
power supply. There are two controls:
•
lowest-priority
—next port
connected causes a shutdown of the
lowest priority port.
•
deny-port
—next port is denied
power, regardless of priority.
• The default is
deny-port.
config inline-power violation-precedence [advertised-class |
operator-limit | max-class-operator | none] ports <portlist> Sets the violation precedence for the
specified ports. A value of advertised-class
will remove/deny power in the case an
802.3af compliant PD consumes power
beyond its advertised class limit. There are
three controls:
•
operator-limit—r
emoves/denies
power if the PD consumes power
beyond the configured
operator-limit
.
•
max-class-operator—r
emoves/denies
power if the PD consumes power
beyond the maximum of the detected
class limit and the
operator-limit
.
• none
—r
emoves/denies power in case
the PD device exceeds the maximum
allowable wattage according to
regulatory maximum of 20,000 mW.
The default is
max-class-operator,
which allows operation of 802.3af
compliant PDs.
config inline-power reserved-budget <milliwatts> ports <portlist> Sets the reserved power on the specified
port(s) to either the default value or the
specified watts. Range is 0 or 3000-20000
mW. The default value is 0 mW. Total
power reserved may be up to but not
greater than the total power for the card. If
all of the power available to the card is
reserved, then the common power pool is
empty.
clear inline-power fault ports <portlist> Clears the fault condition on the specified
ports.
reset inline-power ports <portlist> Power cycles the specified ports. Ports are
immediately de-powered and re-powered,
maintaining current power allocations.
config inline-power detection [auto | discovery-test-only] ports
<portlist> Controls the power detection mechanism
on the port. Test mode forces power
discovery operations, however power is
not supplied to detected PDs.
unconfig inline-power detection ports <portlist> Resets the power detection scheme to the
default.
