Hi, I'm trying to implement overriding methods. This is my code:

Base class: 

use Net::Telnet();
use strict;
use warnings;
package L_Switch;

sub new { 
    my $class = shift;
    my ($location, $ip, $time, $client) = @_;
    my $self = {};
        my $sucClass;
        if ((defined $client) and ($client eq "Veda")){
              $subClass = "L_Switch::L_Veda"; 
        }
    eval "use $subClass;";
    eval "\$self = $subClass -> new();";
}

sub login {
    my $self = shift;
    my $utility = L_Utility -> new();
    $self -> {'telnetConn'} -> open($self -> {ip});
    $self -> {'telnetConn'} -> login($self -> {'username'}, $self -> {
+'password'});
    if ($self -> {'time_out'} == 1)                        # checking 
+timed-out switches
    {
        $self -> {'full_info'} = $self -> {'full_info'} . "," . $self 
+-> {'location'};
        $self -> {'full_info'} = $self -> {'full_info'} . "," . $self 
+-> {'fault'} . "," . $self -> {'time'} . ",,,,,";
        return $self -> {'full_info'};
    }
    return "0";
}

Child class:

package L_Switch::L_Veda;
require L_Switch;
@ISA = qw(L_Switch);
use strict;
use warnings;
use NET::SSH2;

sub new { }    # something in here

sub login {
    my $self = shift;
    $self -> {'ssh'} -> connect($self -> {'ip'});
    $self -> {'ssh'} -> auth_password($self -> {'username'}, $self -> 
+{'password'});
    return 0;
}

Main script:

use L_Switch;
use strict;
use warnings;

my $utility = L_Utility -> new();

my $switch = L_Switch -> new("", '127.0.0.1', "", "Veda");
$switch -> login();
print $switch -> getFullInfo();

when I run the script, an error appeared: Can't locate object method "login" via package "L_Switch::L_Veda" at testSSH.pl line xx. Can anyone tell me what went wrong in my code. Thanks in advance
