I have been using Net::Telnet::Cisco to get information out of cisco routers.(6000 Chasssis running Hybrid.) I use the information to populate a database and keep track of different things on the network. I would like to add information from the layer 3 switch also.(port information for the layer 3 vlans.) The problem is that I can't login to the switch. If I use the wrong password it tells me that the password is wrong, but when I use the correct password I get,
"Use of uninitialized value in pattern match (m//)at /usr/local/lib/perl5/site_perl/5.6.1/Net/Telnet/Cisco.pm line 410, <STDIN> line 2." Here is a sample of the code I am using to test getting into the switch.

#!/usr/local/bin/perl -w 

use Net::Telnet::Cisco;

use strict;

    my $debug = 1;

    my $IP_Addr = "";

    my $switchPassword = "";
    my $routerPassword = "";
    my $routerEnPassword = "";
    my $switchEnPassword = "";

        ## Get the IP Address
    if ($IP_Addr eq "") {
            print "Enter the IP Address: ";
            chop($IP_Addr = <STDIN>);
            system("stty echo");
            print "\n";
        }


        ## Get the switchPassword (make it invisible when entering)
        if ($switchPassword eq "") {
            print "Enter the switch password: ";
            system("stty -echo");
            chop($switchPassword = <STDIN>);
            system("stty echo");
            print "\n";
        }

        print "\tConnecting to $IP_Addr\n" if ($debug);
        my $cs = Net::Telnet::Cisco->new(Host => $IP_Addr);
        my $ok = $cs->login('login', $switchPassword) or die "Error lo
+gging in: @{[ $cs->errmsg() ]}\n";
    print "Logged into Switch\n" if ($debug);

        #Turn off paging
        my @cmd_output = $cs->cmd( 'terminal length 0' );

        #Enter enable mode
    if ($switchEnPassword eq "") {
        print "Enter the enable password for the switch: ";
            system("stty -echo");
            chop($switchEnPassword = <STDIN>);
            system("stty echo");
            print "\n";
    }
    $ok = $cs->cmd("enable\n$switchEnPassword");
    print "entered enable mode\n";    
        my @portInfo = $cs->cmd("sho port status ");
    print "Here";
    my $arrayElement;
    foreach $arrayElement (@portInfo) {
        print "$arrayElement\n";
    } ## end foreach()

    $ok = $cs->disable;
    $ok = $cs->cmd("session 15\n$routerPassword");
    $ok = $cs->cmd("enable\n$routerEnPassword");
    my @intStuff = $cs->cmd("dir");
    foreach $arrayElement (@portInfo) {
        print "$arrayElement\n";
    } ## end foreach()
        exit;

I believe the problem is with my prompt. The only difference I see between the prompts of the router, and the prompts of the switch is that with the router prompts "Password:" and the switch prompts "Enter password:". If anyone knows what I can do to fix this problem I would be very grateful.
