SYNOPSIS

        # Let SNMP::Info determine the correct subclass for you.
        my $c3550 = new SNMP::Info(
                               AutoSpecify => 1,
                               Debug       => 1,
                               # These arguments are passed directly 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";

DESCRIPTION

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

       These devices run IOS but have some of the same characteristics as the Catalyst WS-C
       family (5xxx,6xxx).  For example, forwarding tables are held in VLANs, and extended
       interface information is gleaned 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(...);

GLOBALS

       These are methods that return scalar value from SNMP

       $c3550->vendor()
           Returns 'cisco'

       $c3550->model()
           Will take the translated model number and try to format it better.

            355048 -> 3550-48
            355012G -> 3550-12G

       $c3550->ports()
           Tries to cull the number of ports from the model number.

TABLE METHODS

       These are methods that return tables of information in the form of a reference to a hash.

   Overrides
       $c3550->i_duplex()
           Returns reference to hash of iid to current link duplex setting.

           Software version 12.1(22)EA1a or greater returns duplex based upon the result of
           $c3550->el_duplex().  Otherwise it uses the result of the call to
           CiscoStack::i_duplex().

           See SNMP::Info::Etherlike for el_duplex() method and SNMP::Info::CiscoStack for its
           i_duplex() method.

       $c3550->i_duplex_admin()
           Returns reference to hash of iid to administrative duplex setting.

           Software version 12.1(22)EA1a or greater returns duplex based upon the result of
           $c3550->p_duplex().  Otherwise it uses the result of the call to
           CiscoStack::i_duplex().

           See SNMP::Info::CiscoStack for its i_duplex() and p_duplex() methods.

       $c3550->set_i_duplex_admin(duplex, ifIndex)
           Sets port duplex, must be supplied with duplex and port "ifIndex".

           Speed choices are 'auto', 'half', 'full'.

           Crosses $c3550->p_port() with $c3550->p_duplex() to utilize port "ifIndex".

               Example:
               my %if_map = reverse %{$c3550->interfaces()};
               $c3550->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
                   or die "Couldn't change port duplex. ",$c3550->error(1);
