Can you try to explain it a bit more?
You created 4 classes, (200, 201, 210, 211) so I suppose you want :
200 : http traffic, 4Mbps
201 : ftp traffic, 2Mbps
210 : smtp traffic, 2Mbps
211 : other trafic, 2Mbps
Each class is isolated so it never lends it unused bandwidth to other classes.
And each class is never using unused bandwidth from other classes. So as
example, http has 4Mbps and it never can use the bandwidth of ftp (2Mbps) if
there is no ftp traffic. So the 4Mbps is a maximum bandwidth.
What's the total bandiwidth available? You have 4Mbps for http and 3x2Mbps
for ftp,smtp,other. So the total bandwidth available on the link is 10Mbps?
