[LARTC] restricting bandwidth using TC

[Mike Pearson]

Hello,

 I am trying to get the TC command to work on our debian box to limit
 traffic in and out to 12 Meg.  The command I am using is:
 
 tc qdisc add dev eth0 root tbf rate 12000kbit latency 25ms burst 1600
 tc qdisc add dev eth1 root tbf rate 12000kbit latency 25ms burst 1600
 
 The problem I am having is that the bandwidth exceeds the 12 Meg by
 almost 5 Meg.
 Any help is appreciated.
 
 Thanks
