Hi all, I''ve tried to look for this info in previous messages but had no luck. I''ve a 2.4.20 kernel on an Intel arch., all TC is configured and it seems to work. Anyway, I''ve had some troubles in configuring TBF via tc: 1. when I configure burst or minburst to be, say, 1500b, when I peek the configuration with "tc -s qdisc" the answer is that burst/minburst is equal to 1499. Moreover, any other value I try to configure in "b" unit is always decremented by 1 (3000->2999, and so on). Any clue about that? 2. I also have some stran...

...Setting a very low bandwidth tbf - if the rate is less than my ethernet MTU size then packets appear to just get thrown away Problem 2: Preventing packets being sent instantaneously then arrive at the tbf (because sufficient tokens are available in the bucket?) I have tried to set the burst and minburst parameters but packets still appear to be transmitted too soon (e.g. a 5000bit packet should be delayed for 1 second on a 5000bit link) Problem 3: Is it possible to stop the flow of data when the simulated link is unavailable - whilst still keeping a queue of packets The tc command line I am u...

Hi have set the following tbf tc qdisc add dev eth0 root tbf rate 0.5mbit \ burst 5kb latency 70ms peakrate 1mbit \ minburst 1540 I want to add a filter so the ip traffic pass from it.. plz help me __________________________________ Yahoo!

...s are used for one packet (1500)? 3) And token unrelated question. Does packet droping alway ocurrs or it happens because of bad settings? I have applied this settings on 10mbit ethernet card: tc qdisc add dev eth1 root tbf rate 0.5mbit burst 5kb latency 70ms / peakrate 1mbit minburst 1540 Result: qdisc tbf 8007: dev eth1 rate 512Kbit burst 5Kb/8 mpu 0b peakrate 1Mbit mtu 1539b/8 mpu 0b lat 68.4ms Sent 1284481 bytes 852 pkts (dropped 48, overlimits 1743) Thanks! _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://...

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the
