Martin,
Thanks for the answer. I will study your topology and try to make this
happens.
Att,

Nataniel,
There are probably a handful of ways to solve this problem. Two pop
to mind right away.
: I am still reading about my QoS rules and I need that one of my
: servers (that is into my LAN but has an routing ip address) did
: not get into the qos rules I have. So I want that all traffic
: coming or going to that specifc host did not get shapped by any
: traffic control and do not get even into a QoS class. How can I
: do this?
Option A: specify "default 0" in your HTB qdisc declaration
============================================================
If you install the HTB qdisc with a "default 0" parameter, you are
telling HTB to dequeue unclassified packets as fast as the hardware
will accept the packets. Here's an example:
tc qdisc add dev eth0 root handle 1:0 htb default 0
Now, any unclassified packets will simply be dequeued as fast as
your hardware can do it. If you are trying to remain the bottleneck
between you and the Internet, it is quite likely that this
configuration will defeat your goal.
Option B: make a deeper HTB tree
============================================================
Build the following:
class 1:0, rate = ceil = hardware maximum bitrate
class 2:0, rate = low, ceil = hardware maximum bitrate
class 3:0, rate = low, ceil = maximum for everybody else
root +--- HTB 2:0 --- your "routing ip" (public
| / server?) goes here
+-- HTB 1:0 ---
\
+--- HTB 3:0
|
+--- HTB 3:1
+--- HTB 3:2
+--- HTB 3:3
| ...
+--- HTB 3:N
Now, you simply attach your filters to 1:0, like you did before, and
put all traffic for your "routing ip" into the 2:0 class. If the
rate on class 2:0 stays "low", but its ceiling is the same as the
rate/ceil on 1:0, then you'll effectively get borrowing up to
maximum available throughput for HTB 2:0.
Good luck,
-Martin
