I assume you're trying to match the tos field. u32 uses strtol to read numeric values. Values prefixed with a 0 are assumed to be octal you have to write 0x0011... and 0x00ff.... in order to have it interpreted in hex. Try this: tc filter add dev imq parent 10:0 protocol ip \ prio 1 u32 match ip tos 0x10 0xff flowid 1:10 Regards -- Thomas GRAF <tgraf@xxxxxxx> _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
