It is due to a bit ... weird system used in tc filters and u32. There is global table of all u32 hashed and it is looked up for each filter id - thus it will display them over and over .... You can mitigate it by using "show pref N" so see only part you are interested in. devik On Mon, 8 Apr 2002, Mihai RUSU wrote: > Hi > > I am playing with filters and cbq/htb and I have found this strange thing. > Add some filters using the prio/pref (they seem an alias to me) > parameter like: > tc filter add dev eth0 protocol ip parent 1: pref 5 u32 match ip dst 1.2.3.4 > tc filter add dev eth0 protocol ip parent 1: pref 10 u32 match ip dst 2.3.4.5 > > And try tc filter show dev eth0, you will see that every filter you have > is multiplied by the number of different prio/pref values you have used. > > Thus it looks like you would do this: > > tc filter add dev eth0 protocol ip parent 1: pref 5 u32 match ip dst 1.2.3.4 > tc filter add dev eth0 protocol ip parent 1: pref 5 u32 match ip dst 2.3.4.5 > > tc filter add dev eth0 protocol ip parent 1: pref 10 u32 match ip dst 1.2.3.4 > tc filter add dev eth0 protocol ip parent 1: pref 10 u32 match ip dst 2.3.4.5 > > Why is that?
