29.     =20 etc.

 

 

 

So = here in=20 lines 1, 2, till 14 I made a rood qdisc =93DSMARK=94 and put in it two = =93DSMARK=94=20 classes for marking 0xb8, and 0x28, etc

In = lines 15,=20 16, till 28 I added a =93CBQ=94

 

Now = I have no=20 problem in making filters to classify the incoming traffic according to = their IP=20 header (u32, etc) and to point them to the =93DSMARK=94 classes 1:1, and = 1:2.

 

But = I need to=20 reclassify the packets within the =93CBQ=94 again, according to the mark = they had=20 had.

The = problem=20 here that I tried to use a =93TCINDEX=94 filter

 

E.g. = tc filter=20 add dev eth0 parent 2:0 protocol ip prio 1 tcindex handle 1 tcindex = classid=20 2:1

 

This = filter is=20 supposed to point the traffic with the mark 0xb8 to classid=20 2:1

 

But = when I=20 added the rest of the filters to point to the classes 2:2, 2:3, 2:d .. = only some=20 of the filters worked well and the rest didn=92t

 

Also = in that=20 =93TCINDEX=94 filter, what value does that handle take? Is it in hex or = decimal or=20 is it just the marking classid or what?

 

 

BEST = REGARDS=20
