Subject: [LARTC] Warnings with and without r2q
Date: Wed, 12 Mar 2003 18:31:44 +0000	[thread overview]
Message-ID: <marc-lartc-104749414411587@msgid-missing> (raw)

Hi everyone,

My HTB script is showing me those "r2q change" warnings. I read that I
should test with r2q values to gain accuracy and stop the warnings but I
made some tests with r2q and with burst and I still get the warnings. Any
ideas on this issue will be very helpful. The script seems to be working as
the bandwidth for the IPs is being shaped.
The NIC works at 100mbit and the Internet link that is shared is 128kbit.
iptable rules mark the packets on the PREROUTING and POSTROUTING chain

Here is what I tested and then the rules I´m using:

With this tests:
1. Script with no r2q and no burst
2. Script with "r2q 1" and no burst
3. Script with no r2q and "burst 2k"
4. Script with "r2q 1" and "burst 2k"

I get the same warnings:

htb*g j\x154890413
HTB: quantum of class 10001 is big. Consider r2q change
HTB: quantum of class 10010 is big. Consider r2q change
HTB: quantum of class 10021 is small. Consider r2q change
...
...
...
HTB: quantum of class 10028 is small. Consider r2q change
htb*g j\x154890421
HTB: quantum of class 10001 is big. Consider r2q change
HTB: quantum of class 10010 is big. Consider r2q change
HTB: quantum of class 10021 is small. Consider r2q change
...
...
...
HTB: quantum of class 10028 is small. Consider r2q change

With this tests:
5. With "r2q 2" and no burst
6. With "r2q 2" and "burst 2k"

I get only this:

htb*g j\x154890500
HTB: quantum of class 10001 is big. Consider r2q change
HTB: quantum of class 10010 is big. Consider r2q change
htb*g j\x154890508
HTB: quantum of class 10001 is big. Consider r2q change
HTB: quantum of class 10010 is big. Consider r2q change

Here's the script I´m using (with the burst parameter):
