=head1 NAME
SNMP::Info::Layer3::Netscreen - SNMP Interface to Juniper Netscreen Devices
=head1 AUTHOR
Kent Hamilton
=head1 SYNOPSIS
#Let SNMP::Info determine the correct subclass for you.
my $netscreen = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $netscreen->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
Netscreen device through SNMP. See inherited classes' documentation for
inherited methods.
