I am using the script below to simulate a very high bandwidth connection.I find that I could not turn the bandwidth knob up to 100Mbit.I have had a look at this generally,but could not find an answer.any help would much appreciated as i have spent a lot of time on this and have not found any answers anywhere.
In my test,I have four network cards and their rate are all 1000Mbps.

(using "tc -s class show dev eth1" to list result,if the rate of class 1:21 is 100Mbit,the result is between 99M and 100M;
if the rate of class 1:21 is 150Mbit ,the result is between 45M and 50M;)
if the rate of class 1:21 is 150Mbit ,the result is between 45M and 50M;)
Thank you and regards.
