Take a look at what the code in your while loop would do for each line of code:

• Checks: Running 'show port | match "Up    Yes" | count'
  OK, it matches /show port/, so it would skip rest of the body of the while loop.
• Count: 23 lines
  It doesn't match /show port/, so it goes to the next line in the loop.
  It matches /Count:\s+(\d+)/, so it would add the value to $checks{port}{$stage}
  It doesn't match /show router interface/, so it goes to the next line in the loop.
  It matches /Count:\s+(\d+)/, so it would add place the value to in $checks{l3}{$stage}
  There's nothing else in the loop to do...
• Checks: Running 'show router interface | match "Up " | count'
  It doesn't match /show port/, so it goes to the next line in the loop.
  It doesn't match /Count:\s+(\d+)/, so it ignores the body of the if statement.
  It matches /show router interface/, so it would skip the rest of the body of the while loop.
• Count: 4 lines
  It doesn't match /show port/, so it goes to the next line in the loop.
  It matches /Count:\s+(\d+)/, so it would add the value to $checks{port}{$stage}
  It doesn't match /show router interface/, so it goes to the next line in the loop.
  It matches /Count:\s+(\d+)/, so it would add place the value to in $checks{l3}{$stage}
  There's nothing else in the loop to do...

So it looks like you're expecting 'next' to mean "read the next line" instead of "ignore the rest of the loop".

I expect you probably want something like:

while (my $line = <INPUT>) {
   my item = "UNKNOWN";
   if ($line =~ /show port/)             { $item = "port"; }
   if ($line =~ /show router interface/) { $item = "l3"; }

   if ($line =~ /Count:\s+(\d+)/) { $checks{$item}{$stage} = $1; }
}

Update: Pressed "create" just a bit too soon!

Update: As AnomalousMonk mentions, it's not adding the count value.
