This Integer32 object (range -1 to 255) specifies the Type of Service value a packet's IP header must carry to match this General Access List entry, with -1 serving as a wildcard for any ToS value. It lets an administrator write rules that treat traffic differently based on its marked priority, such as isolating voice or video traffic tagged with a specific ToS byte. For example, setting this to 184 would match packets marked with that particular ToS/DSCP value while any other value would pass through unmatched by this entry.
