| 
 | |
| =head1 SYNOPSIS
 | |
| 
 | |
|  # Let SNMP::Info determine the correct subclass for you.
 | |
|  my $ubnt = new SNMP::Info(
 | |
|                           AutoSpecify => 1,
 | |
|                           Debug       => 1,
 | |
|                           DestHost    => 'myswitch',
 | |
|                           Community   => 'public',
 | |
|                           Version     => 2

 | |
| 
 | |
| =head1 DESCRIPTION
 | |
| 
 | |
| Provides abstraction to the configuration information obtainable from
 | |
| Ubiquiti Access Point through SNMP.
 | |
| 
 | |
| For speed or debugging purposes you can call the subclass directly, but not
 | |
| after determining a more specific class using the method above.
