[LARTC] A question about tbf

I use the tbf to limit my bandwidth, and not error msg.
But I can't link to my server.

My config isjust one line (is that ok????) :

tc qdisc add dev eth0 root handle 10: tbf limit 10Mbit burst 20 rate 2000KBPS

Please give me some advice, thanks.

Increase your burst it value at list MTU i.e 1500 byte 

rate=ST*burst (ST system timer 100HZ for intel/amd 1024 for alpha)
       rate
burst=------- and burst>MTU
        ST
