[LARTC] Ultimate Traffic Conditioner

[Jan Coppens]

Hi all,   When I try to run the ultimate traffic conditioner (cbq implementation), I get this strange output:     /tc# ./ultimate /tc# tc filter show dev eth1 filter parent 1: protocol ip pref 10 u32 filter parent 1: protocol ip pref 10 u32 fh 803: ht divisor 1 filter parent 1: protocol ip pref 10 u32 fh 803::800 order 2048 key ht 803 bkt 0 flowid 1:20   match 00000000/00000000 at 16 filter parent 1: protocol ip pref 10 u32 fh 802: ht divisor 1 filter parent 1: protocol ip pref 10 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 1:10   match 00060000/00ff0000 at 8   match 05000000/0f00ffc0 at 0   match 00100000/00ff0000 at 32 filter parent 1: protocol ip pref 10 u32 fh 801: ht divisor 1 filter parent 1: protocol ip pref 10 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:10   match 00010000/00ff0000 at 8 filter parent 1: protocol ip pref 10 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10   match 00100000/00ff0000 at 0 filter parent 1: protocol ip pref 11 u32 filter parent 1: protocol ip pref 11 u32 fh 803: ht divisor 1 filter parent 1: protocol ip pref 11 u32 fh 803::800 order 2048 key ht 803 bkt 0 flowid 1:20   match 00000000/00000000 at 16 filter parent 1: protocol ip pref 11 u32 fh 802: ht divisor 1 filter parent 1: protocol ip pref 11 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 1:10   match 00060000/00ff0000 at 8   match 05000000/0f00ffc0 at 0   match 00100000/00ff0000 at 32 filter parent 1: protocol ip pref 11 u32 fh 801: ht divisor 1 filter parent 1: protocol ip pref 11 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:10   match 00010000/00ff0000 at 8 filter parent 1: protocol ip pref 11 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 11 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10   match 00100000/00ff0000 at 0 filter parent 1: protocol ip pref 12 u32 filter parent 1: protocol ip pref 12 u32 fh 803: ht divisor 1 filter parent 1: protocol ip pref 12 u32 fh 803::800 order 2048 key ht 803 bkt 0 flowid 1:20   match 00000000/00000000 at 16 filter parent 1: protocol ip pref 12 u32 fh 802: ht divisor 1 filter parent 1: protocol ip pref 12 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 1:10   match 00060000/00ff0000 at 8   match 05000000/0f00ffc0 at 0   match 00100000/00ff0000 at 32 filter parent 1: protocol ip pref 12 u32 fh 801: ht divisor 1 filter parent 1: protocol ip pref 12 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:10   match 00010000/00ff0000 at 8 filter parent 1: protocol ip pref 12 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 12 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10   match 00100000/00ff0000 at 0 filter parent 1: protocol ip pref 13 u32 filter parent 1: protocol ip pref 13 u32 fh 803: ht divisor 1 filter parent 1: protocol ip pref 13 u32 fh 803::800 order 2048 key ht 803 bkt 0 flowid 1:20   match 00000000/00000000 at 16 filter parent 1: protocol ip pref 13 u32 fh 802: ht divisor 1 filter parent 1: protocol ip pref 13 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 1:10   match 00060000/00ff0000 at 8   match 05000000/0f00ffc0 at 0   match 00100000/00ff0000 at 32 filter parent 1: protocol ip pref 13 u32 fh 801: ht divisor 1 filter parent 1: protocol ip pref 13 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:10   match 00010000/00ff0000 at 8 filter parent 1: protocol ip pref 13 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 13 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10   match 00100000/00ff0000 at 0 /tc#   As you can see, the script adds way to many u32 filters. I did some testing, and figured out the problem has something to do with the different priorities. when I give each u32 filter the same priority, I get the right number of filters.   Is this output correct? If not, what can be the problem?   thanks, Jan   --- Jan Coppens Ghent University - IMEC   Department of Information Technology (INTEC) Broadband Communication Networks (IBCN)   Sint-Pietersnieuwstraat, 41 B-9000, Gent Belgium   E-mail: [EMAIL PROTECTED] Phone: +32 (0)9 267 35 90 Fax: +32 (0)9 267 35 99
