SNMP::Info::PowerEthernet - SNMP Interface to data stored in POWER-ETHERNET-MIB.

# Let SNMP::Info determine the correct subclass for you. my $poe = new SNMP::Info( AutoSpecify => 1, Debug => 1, DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost.\n"; my $class = $poe->class(); print "SNMP::Info determined this device to fall under subclass : $class\n";
POWER-ETHERNET-MIB is used to describe PoE (IEEE 802.3af)
Create or use a device subclass that inherit this class. Do not use directly.
For debugging purposes you can call this class directly as you would SNMP::Info
my $poe = new SNMP::Info::PowerEthernet (...);
none.
These are methods that return tables of information in the form of a reference to a hash.
Selected values from the pethPsePortTable
pethPsePortTable
Administrative status: is this port permitted to deliver power?
pethPsePortAdminEnable
Current status: is this port delivering power, searching, disabled, etc?
pethPsePortDetectionStatus
Device class: if status is delivering power, this represents the 802.3af class of the device being powered.
pethPsePortPowerClassifications
A mapping function from the pethPsePortTable INDEX of module.port to an ifIndex. The default mapping ignores the module (returning undef if there are any module values greater than 1) and returns the port number, assuming that there is a 1:1 mapping.
ifIndex
This mapping is more or less left up to the device vendor to implement; the MIB gives only very weak guidance. A given device class may implement its own version of this function (e.g., see Info::CiscoPower).
The power supply's capacity, in watts.
pethMainPsePower
The power supply's operational status.
pethMainPseOperStatus
How much power, in watts, this power supply has been committed to deliver. (Note: certain devices seem to supply this value in milliwatts, so be cautious interpreting it.)
pethMainPseConsumptionPower
The threshold (in percent) of consumption required to raise an alarm.
pethMainPseUsageThreshold
