SNMP::Info::Layer3::Steelhead - SNMP Interface to Riverbed Steelhead WAN
optimization appliances.

=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $riverbed = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

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

=head1 DESCRIPTION

Abstraction subclass for Riverbed Steelhead WAN optimization appliances.

For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above. 

 my $riverbed = new SNMP::Info::Layer3::Steelhead(...);
