Your switch has no clue what your incoming or outgoing bandwidth
capabilities are, unless it has some configuration you didn't mention.
The only way to effectively manage your ISP connection is to pretend
like you have less bandwidth than you really do. Thus, you are
pretending like you control both ends of the link. So, you figure out
your maximum download and upload speeds without QoS restrictions and
then reduce the figures by 10 - 30%. Thereby giving your QoS
implementation some overhead to work and keep your link unsaturated.
