SYNOPSIS

13        # Let SNMP::Info determine the correct subclass for you.
14        my $poe = new SNMP::Info(
15                                 AutoSpecify => 1,
16                                 Debug       => 1,
17                                 DestHost    => 'myswitch',
18                                 Community   => 'public',
19                                 Version     => 2
20                               )
21           or die "Can't connect to DestHost.\n";
22
23        my $class      = $poe->class();
24        print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

27       POWER-ETHERNET-MIB is used to describe PoE (IEEE 802.3af)
28
29       Create or use a device subclass that inherit this class.  Do not use
30       directly.
31
32       For debugging purposes you can call this class directly as you would
33       SNMP::Info
34
35        my $poe = new SNMP::Info::PowerEthernet (...);
36
37   Inherited Classes
38       none.
39
40   Required MIBs
41       POWER-ETHERNET-MIB
42

GLOBALS

44       none.

TABLE METHODS

47       These are methods that return tables of information in the form of a
48       reference to a hash.
49
50   Power Port Table
51       Selected values from the "pethPsePortTable"
52
53       $poe->peth_port_admin()
54           Administrative status: is this port permitted to deliver power?
55
56           "pethPsePortAdminEnable"
57
58       $poe->peth_port_status()
59           Current status: is this port delivering power, searching, disabled,
60           etc?
61
62           "pethPsePortDetectionStatus"
63
64       $poe->peth_port_class()
65           Device class: if status is delivering power, this represents the
66           802.3af class of the device being powered.
67
68           "pethPsePortPowerClassifications"
69
70       $poe->peth_port_ifindex()
71           A mapping function from the "pethPsePortTable" INDEX of module.port
72           to an "ifIndex".  The default mapping ignores the module (returning
73           undef if there are any module values greater than 1) and returns
74           the port number, assuming that there is a 1:1 mapping.
75
76           This mapping is more or less left up to the device vendor to
77           implement; the MIB gives only very weak guidance.  A given device
78           class may implement its own version of this function (e.g., see
79           Info::CiscoPower).
80
81       $poe->peth_port_neg_power()
82           The power, in milliwatts, that has been committed to this port.
83           This value is derived from the 802.3af class of the device being
84           powered, but may be overridden by a subclass that has information
85           from another source (e.g., if a different protocol, such as CDP,
86           was used to negotiate the power level.)
87
88   Power Supply Table
89       $poe->peth_power_watts()
90           The power supply's capacity, in watts.
91
92           "pethMainPsePower"
93
94       $poe->peth_power_status()
95           The power supply's operational status.
96
97           "pethMainPseOperStatus"
98
99       $poe->peth_power_consumption()
100           How much power, in watts, this power supply has been committed to
101           deliver.  (Note: certain devices seem to supply this value in
102           milliwatts, so be cautious interpreting it.)
103
104           "pethMainPseConsumptionPower"
105
106       $poe->peth_power_threshold()
107           The threshold (in percent) of consumption required to raise an
108           alarm.
109
110           "pethMainPseUsageThreshold"
