The problem beeing that GRED doesn't use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! Have you seen this http://www.opalsoft.net/qos/DS-27.htm Though if it works you don't need it :-) But when i try to add an HTB before the GRED, everything goes to hell. You may need to repeat filters to get HTB to go from root to GRED (well you do with PRIO) eg. from a usenet post. > Hi Everyone > > I'm running Fedora Core 2 as a router and am having problems getting the > PRIO qdisc to work. > > I'm using the Iperf utility to generate traffic flows between computers on > either side of the Fedora box.

Seems HTB doesn't forward direct to prio bands from root so you have to repeat the filters. Below is what just seemed to work for me - It works without the bfifos aswell but you don't get per band stats with tc -s qdisc ls dev eth0 if you don't have them. Andy.

Those are qdisc specific statistics. borrowed may even have a different unit depending on your compile time options.

You may specify whatever time interval you prefer. Note: the rate estimator uses sent statistics which are counted in enqueue, therefore no borrowing taken into account. > the lended and borrowed stats refer.

In HTB yes, CBQ can also count in bytes. ___ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

[LARTC] qdisc statistics
Hi, I am trying to relate the lended and borrowed statistics to the others and, in particular, compare them with the assigned rates for each class. My understanding is that the lended and borrowed stats are expressed as a number of packets but over what time period do the numbers refer? In addition, for a particular class why do the lended and borrowed figures add up to the sent value? That is, if a class 'lends' bandwidth, why do the packets still appear in its 'sent' stat alongside those it borrowed? How do I obtain the actual rate used for a class - as opposed to the assigned rate? This is what I really want and I was hoping there would be some relationship such as: actual rate = assigned rate + borrowing rate - lending rate except, as mentioned above, I need to know the time period over which the lended and borrowed stats refer. Also, lended and borrowed are given in packets, the rates are expressed in bytes or bits per second, so presumably, I will need to calculate an average packet size.

[LARTC] Giving high proprity to SIP packets
Hi I want to give high priority to SIP packets that are flowing out of my system. I want to use RED or TBF for it. I dont know where to start from. Since my system is not supporting HTB..i am not able to get hold of some guidelines to implement the same. Looking forward to some help. regards Sriram ___ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
