similar to: ceil, cburst, prio not working?

Hi all :) If I set the burst/cburst parameter to, let''s say, 1500, the command "tc -s -d class show dev eth0" says that the value is 1499b/8 instead of the (correct?) 1500b/8. Is this right or am I doing anything wrong? Many thanks in advance :) Raúl Núñez de Arenas Coronado -- Linux Registered User 88736 | http://www.dervishd.net http://www.pleyades.net

Hello. I am wondering if the default (auto-computed) burst and cburst parameters are appropriate values for my application. I have a 100 mbit interface which is connected to a 16 mbit uplink. I am sharing this bandwidth into a set of partitions (tc classes) defined as follows: root class [1:1] |

All: Does anyone know what the burst and cburst parameter do? My understanding so far: * I see a lot of different definitions on the web. It seems like burst is the number of bytes sent before serving other queues/classes. So if burst was 1000 bytes and class rate was 100kibit per second. It would send 1000 bytes each time the scheduler service that queue to a rate of 100 kbit per

i am trying to do some traffic classification using the PRIO qdisc and i am having a few problems.

Hi, we have upgraded a gateway machine for our network and suddenly shaping doesn''t work as it used to. Before the upgrade the traffic was shaped correctly - both OUTPUT and FORWARD packets shared the same class and it just worked. But now only FORWARD packets are shaped, OUTPUT uses whole line bandwidth. This is a piece of output from tc -s class show dev eth1: class htb 1:894 parent

Hello I have a 64kbits link to location and I need to limit the traffic of a machine (10.200.0.86) to this location to ensure that this machine will no use all th bandwidth, and I did a rule to this situation where the machine has it bandwith limited to 10kbits if there is other traffic to this location, otherwise it can use up to 54 kbits. tc qdisc add dev eth0 root handle 1: htb ... tc

What''s going on here? I''m spewing UDP traffic at this thing, and it is exceeding the ceil, (i watched it for a few minutes, it didn''t slow down).

Hello! I am using shapping whith htb. My question is what are the propper values I can use in rate/ceil. I use htb.init for quick building of my classes/rules and have 2 groups of clients with 2 different bandwidth assignemet : A. 16--->48kbps B. 16---->128Kbps It seems to work everything OK, but can I use lower values for rate like 8Kbps ? What about using 32-->96Kbps? I let htb to

Hello all, when running tc -s -d class show dev eth, the parent class rate and ceil are different to the configuration? his is the first time I have used HTB so I may have made some basic mistakes.
