=head1 SYNOPSIS
|
|
|
|
#Let SNMP::Info determine the correct subclass for you.
|
|
|
|
my $airespace = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,

|
DestHost => 'myswitch',

|
Community => 'public',

=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from
|
|
Cisco (Airespace) Wireless Controllers 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.
