Hi anyone I try to use htb and got some strange situation My hbt config is root htb with default to 999 class Then I make 2 classes 999 and 998 And make many many (near 60) leafs attached to 998 root ! ! 999 998 ---...---> many leafs root attached to ethernet dotQ subinterface 999 make rate where high (50Mbit) but according to tc -s class show dev <intf> traffic at this class extremally small (near 9,6Kbit) so any other traffic going throw 998 class On 998 class I make rate X Mbit''s (without.same ceil) Than I make many many leafs with it''s own rate/ceil Summary of rate (and ceil) is biggest then X I think that I have 3 level of queue at my config High level - root htb (unused because speed too high) Second level - queue at classes 998 and 999 And next level - queue and any leaf But I can''t see queuning at class 998 even if traffic more then X Mbits I think I got priority queue (I set prio at nex level classes) but nothing I got and at interface I got high speed that X Mbits Why? Could I do something to get such config? M-m-m and some another information. To any leaf I connect sfq qdisc. To 998 I doesn''t connect anything. May be I need to connect prio queuening discipline? Also I want to ask another question If I make filter like 1:1 to parent 1: and than make two another filters 1:2 and 1:3 with parent 1:1 is I got logical and between 1:1 and 1:2/1:3? -- Best regard, Aleksander Trotsai aka MAGE-RIPE aka MAGE-UANIC My PGP key at ftp://blackhole.adamant.ua/pgp/trotsai.key[.asc] Big trouble - Someone else stole your IP address, call the Internet detectives! _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Hi All, I am runnnig a small network of Linux-routers.In this, I want to measurre some traffic performance. For this I have to make sure that clock of all the routers is synced upto millisecond or better. To achive this, I did "ntpdate <server >".(ntp syncing) After doing this I noticed that my nodes are no synced accurately. In my testing I found that receive time was less than transit time by some milli/micro seconds. Can any one plaese suggest me how can I achive micro(may be milli) second or better syncing. Thanks, Nitin __________________________________________________ Do you Yahoo!?
