Thanks for the suggestions. I have tried 2 ways and I still can't get some of the info. Lets assume the lines that I store at my @array are the following:

I can extract the switch name but I cannot sxtract the IP address for the switch for some reason

    foreach $Line ( @RouterOutput ) {
        if ( $Line =~ m/^Device / ) {
            @Data = split( ' ', $Line );
            $SwitchName = $Data[ 2 ] ;
            last ;
        }
        if ( $Line =~ m/^IP / ) {
            @Data = split( ' ', $Line );
            $SwitchIP = $Data[ 2 ] ;
            last ;
        }
    }
