Resetting traffic history

[Michael Slinn <mslinn@xxxxxxxxxxx>]

I'm a tc newbie, and I think I am close to being able to use it to control one of the virtual web sites on our Gentoo Linux server.  The site has it's own IP address.  I have a bit of a problem in that the way I originally configured tc, the busy site grabbed all the bandwidth, leaving none for the other (and more important) sites.  Here is how I had configured it:

tc qdisc replace dev $NIC root tbf rate $RATE_TOTAL latency 50ms burst $BURST

The total data rate was pegged within acceptable limits, but the problem is that data stopped flowing after tc was active after a few hours.  The busy site had a few peak periods and presumably used up all the traffic allotment.  Perhaps tc remembers the traffic between invocations?

I then tried a slightly more sophisticated setup:

tc qdisc del dev $DEV root
tc qdisc  add dev $NIC root handle 1: cbq avpkt 1000 bandwidth 1000mbit
tc class  add dev $NIC parent 1: classid 1:1 cbq rate $RATE_PROBLEM allot 1500 prio 5 bounded # isolated
tc filter add dev $NIC parent 1: protocol ip prio 16 u32 match ip dst $IP flowid 1:1

Unfortunately, I still don't get any traffic flowing while tc is active now.  Seems that I need to reset something.  Any suggestions?  I've shut down the problem site and disabled tc while I try to figure out a solution.

Thanks for your help!
