=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you.
 my $allied = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myhub',
                          Community   => 'public',
                          Version     => 1
                        )
    or die "Can't connect to DestHost.\n";

 my $class = $allied->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

Provides abstraction to the configuration information obtainable from a
Allied device through SNMP. See inherited classes' documentation for
inherited methods.

These are methods that return scalar value from SNMP

=head2 Overrides

=item $allied->vendor()

Returns 'allied' :)

=item $allied->os()

Returns 'allied'

=item $allied->os_ver()

Culls Version from description()

=item $allied->root_ip()

Returns IP Address of Managed Hub.

(C<actualIpAddr>)

=item $allied->model()

Tries to cull out C<AT-nnnnX> out of the description field.

=head2 Overrides

=over

=item $allied->i_name()

Returns reference to map of IIDs to human-set port name.

=item $allied->i_up()

Returns reference to map of IIDs to link status.  Changes
the values of ati_up() to 'up' and 'down'.
