well, so what seems to be the problem?

#!/usr/bin/env perl
#

use strict;
use warnings;

open F, "<fff" or die "Aaaahg...";

# current system
my $system;

# our params here
my %box;
my %bin;
my %bout;
my %desc;

while (<F>) {
    /^system\d+-server$/ and do {$system= $_; next};
    /^HW a2b.*\(.*\)$/ and $box{$system}= $_;
    s/^\s*(\d+) packets input.*$/$1/ and $bin{$system}= $_;
    s/^\s*(\d+) packets output.*$/$1/ and $bout{$system}= $_;
    s/^Description: (.*)$/$1/ and $desc{$system}= $_;
}

foreach (keys %desc) {
    print "System: ". $_;
    print "Box: ". $box{$_};
    print "ByteIn: ". $bin{$_};
    print "Byteout: ". $bout{$_};
    print "Description: ". $desc{$_};
}
