your device, may not have a queue length,
try
ip link set $DEV txqueuelen 1000
and see whether it limits correctly.

I added the call to ip link set and I am still seeing huge bandwidth
consumption. Any other ideas?

You're setting a rate value but not a ceil value. Rate values can be
exceeded, ceil values cannot.
You may also need an extra class with an overall rate limit, and then
your leaf classes attached to that (I don't know if that's required, but
the examples I have seen have used that). I can provide examples if
needed.

An example would be nice.
I also tried using the token bucket filter:
/sbin/tc qdisc add dev $DEV root tbf rate 1mbit latency 5ms burst 2048
Which also does not seem to be limiting the bandwidth.
I appreciate any help you can offer.
Thank you,
Neil

Hello all:
It looks like tc thinks I set a token bucket filter on my interface:
# tc -s qdisc ls dev v1252
qdisc tbf 8006: root refcnt 2 rate 1000Kbit burst 2Kb lat 5.0ms
Sent 6788208 bytes 51190 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
But I am still seeing bandwidth consumption hitting 80mbit/sec.
Any ideas why it would not be working?
This is a CentOS server with all the latest updates installed.
V1252 is a KVM guest running on the machine.
Thank you,
Neil

But, I am still seeing huge consumption of bandwidth from that server.
Take a look at the attached graph.

To set a ceil value, just add ceil 10Mbit after your rate 10Mbit in
your HTB script.
BTW, please fix your spam detector, i call it racism
to think all email contains Chinese character as spam.

A VPS server shouldn't be any different to a normal server (although I
have never tried). Are you sure you are attaching to the correct
interface and doing the correct egress/ingress shaping? It won't limit
both ways by default.
Can you post your rules that are/aren't working please?

Here are the rules I am using. They throttle the bandwidth into
the VPS just fine, but they are not working to throttle the bandwidth
out of the VPS:
IP=a.b.c.d
DEV=v1208
/sbin/tc qdisc del dev $DEV root
/sbin/tc qdisc add dev $DEV root handle 1: htb default 30
/sbin/tc class add dev $DEV parent 1: classid 1:1 htb rate 500kbit
/sbin/tc class add dev $DEV parent 1: classid 1:2 htb rate 500kbit
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip dst $IP flowid 1:1
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip src $IP flowid 1:2
Thank you,

Assuming that these are your only rules, these will be doing the egress
from device v1208, which I am assuming is the upload for the VPS.
If that is the case, you'll need an ingress for the download. The
following page has an example:

Of course, I can try to remember to do so for your particular posts to
that particular mailing list, although I'd have to rearrange the email
addresses as neither a reply-to or reply-all would work.
But it's better netiquette for you not to reject people's emails.

You were right, I needed to add an ingress filter to limit the upload
speed of the VPS. So, now here are my rules:
IP=a.b.c.d
DEV=v1208
/sbin/tc qdisc del dev $DEV root
/sbin/tc qdisc add dev $DEV root handle 1: htb default 30
/sbin/tc class add dev $DEV parent 1: classid 1:1 htb rate 5mbit
/sbin/tc class add dev $DEV parent 1: classid 1:2 htb rate 5mbit
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip dst $IP flowid 1:1
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip src $IP flowid 1:2
/sbin/tc qdisc del dev $DEV ingress
/sbin/tc qdisc add dev $DEV ingress handle ffff:
/sbin/tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate 5mbit burst 500k drop flowid :1
I am attaching a graph that shows the bandwidth during two large file transfers.
The first part of the graph is when I was doing a large download.
It sits exactly at 5mbit/sec which is what I want it to do.
Next, I stopped the download and started an upload. That is sitting at
about 60kbit/sec and not going any higher.
Any ideas why the ingress rules are limiting the bandwidth so much?
Thank you,
Neil

I should correct this statement that I made. If not specified, a ceil
value defaults to the rate value.
> Rate values can be exceeded, ceil values cannot.
This, of course, is still true.
