LARTC - Jul 2006 - I need help with tc filters!!!!!

Hi Everybody!

    I need help! I''m doing a tc script with tc filters that have match
the Type of Service field in the IP header. This is the script I am using to
setup the filters.

tc filter add dev $DEV parent 1: protocol ip prio $PRIO_CONTROL u32 match ip
protocol 6 0xff \

match u32 00190000 00ff0000 at 0 flowid 1:10



tc filter add dev $DEV protocol ip parent 1: prio $PRIO_VIDEO u32 match ip
protocol 17 0xff \

match u32 001b0000 00ff0000 at 0 \

police rate ${VIDEO_LEVEL_0_BW}kbit buffer ${VIDEO_BUFFER}k drop flowid 1:13



tc filter add dev $DEV protocol ip parent 1: prio $PRIO_VIDEO u32 match ip
protocol 17 0xff \

match u32 000b0000 00ff0000 at 0 \

police rate ${VIDEO_LEVEL_1_BW}kbit buffer ${VIDEO_BUFFER}k drop flowid 1:14




tc filter add dev $DEV protocol ip parent 1: prio $PRIO_VIDEO u32 match ip
protocol 17 0xff \

match u32 00130000 00ff0000 at 0 \

police rate ${VIDEO_LEVEL_2_BW}kbit buffer ${VIDEO_BUFFER}k drop flowid 1:15




tc filter add dev $DEV protocol ip parent 1: prio $PRIO_VIDEO u32 match ip
protocol 17 0xff \

match u32 00030000 00ff0000 at 0 \

police rate ${VIDEO_LEVEL_3_BW}kbit buffer ${VIDEO_BUFFER}k drop flowid 1:16



Please, if someone could help me, I will be so glad! The role script is the file
attached

Thanks a lot

Luciana

You don''t say what the problem is - If it''s that the tos
doesn''t match
it may be because the last bit is supposed to be cleared/unused and you 
are matching set?
