Wouldn't this be a great use for a hash? Just search for any keyword on the line and if you find one, increment the appropriate hash entry. Then read from $output{VLAN}, etc to find these. You should only have 1 match string. Maybe you could do something like this: 
  my %flag = ();
  while (<IN>) {
      s/\.\d+\s*=\s*/_/; # Format the string to match nicer
      $flag{$1}++ if /(VLAN|if(?:Oper|Admin)Status_(?:up|down))/;
  }

  # Now access $flag{VLAN}, $flag{ifOperStatus_up}, etc.

I'm not sure if the substitute makes you take more time, but at least you won't parse through the entire file 4 times. Sometimes it really does make more sense to parse the file one line at a time, instead of in a huge block. This particularly makes sense because the lines have such regularity.
