Hi,
I need to set filter-hash and use source-port as hashkey. It seems that
I can't use "hashkey" without using "match".
I am using following commands:
tc qdisc add ... root handle 1:0 htb
# Loop to add 1000 classes (i = 1 to 1000)
tc class add ... parent 1:0 classid 1:$i
#set filters
tc filter add ... protocol ip parent 1:0 u32
tc filter add ... protocol ip parent 1:0 handle 2: u32 divisor 256
# Loop to add 1000 filter: one for each class
# $p is for port; $b is the bucket id (0 to 256); $f is for classid (1
to 1000)
tc filter add ... parent 1:0 u32 match ip sport $p 0x ht 2:$b:
flowid 1:$f
#hashkey
tc filter add ... protocol ip parent 1:0 u32 hashkey mask 0x at 20
link 2:
Problem is the last command. I want to match all the traffic coming to
the interface and use lower-order of the source-port to decide the
filter-bucket.
When I run the last command, it throws an error:
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
Do we need to necessarily use "match ip .." before using "hashkey"? If
so, how do I match all the traffic?
Thanks for the help,
deepak
