=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $poe = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
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";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The Info::PowerEthernet class needs a per-device helper function to
|
|
properly map the pethPsePortTable to ifIndex values. This class
|
|
provides that helper, using CISCO-POWER-ETHERNET-EXT-MIB.
|
|
It does not define any helpers for the extra values that this MIB
|
|
contains.
|
|
|
|
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::CiscoPower (...);
|
|
|
|
=head2 Inherited Classes
|
|
|
|
none.
|
|
|
|
Note that it requires that the device inherits from Info::Entity.
