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

       Bill Fenner

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 (...);

        # 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";

       These are methods that return tables of information in the form of a reference to a hash.

   PowerPortTable
       Selected values from the "pethPsePortTable"

       $poe->peth_port_admin()
           Administrative status: is this port permitted to deliver power?

           "pethPsePortAdminEnable"

       $poe->peth_port_status()
           Current status: is this port delivering power, searching, disabled, etc?

           "pethPsePortDetectionStatus"

       $poe->peth_port_class()
           Device  class:  if  status is delivering power, this represents the 802.3af class of the device being
           powered.

           "pethPsePortPowerClassifications"

       $poe->peth_port_ifindex()
           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.

           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).

       $poe->peth_port_neg_power()
           The power, in milliwatts, that has been committed to this port.   This  value  is  derived  from  the
           802.3af  class  of the device being powered, but may be overridden by a subclass that has information
           from another source (e.g., if a different protocol, such as CDP, was  used  to  negotiate  the  power
           level.)

   PowerSupplyTable
       $poe->peth_power_watts()
           The power supply's capacity, in watts.

           "pethMainPsePower"

       $poe->peth_power_status()
           The power supply's operational status.

           "pethMainPseOperStatus"

       $poe->peth_power_consumption()
           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"

       $poe->peth_power_threshold()
           The threshold (in percent) of consumption required to raise an alarm.

           "pethMainPseUsageThreshold"
