SNMP::Info::Layer3::C3550 - Perl5 Interface to Cisco Catalyst 3550 Layer 2/3 Switches running IOS

=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $c3550 = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          # These arguments are passed directly on to SNMP::Session
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

 my $class      = $c3550->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

Abstraction subclass for Cisco Catalyst 3550 Layer 2/3 Switches.  

These devices run IOS but have some of the same charactersitics as the Catalyst WS-C family (5xxx,6xxx). 
For example, forwarding tables are held in VLANs, and extened interface information
is gleened from CISCO-SWITCH-MIB.

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

 my $c3550 = new SNMP::Info::Layer3::C3550(...);
