POWER-ETHERNET-MIB.

SYNOPSIS
# 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";
DESCRIPTION
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 (...);
Inherited Classes
none.
Required MIBs
POWER-ETHERNET-MIB
GLOBALS
none.
TABLE METHODS
These are methods that return tables of information in the form of a
reference to a hash.
Power Port Table
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.)
Power Supply Table
$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"
