Hi
trying to do test case:
defaulthost ~ # tc qdisc del dev eth0 root handle 1: htb
defaulthost ~ # tc qdisc add dev eth0 root handle 1: htb
defaulthost ~ # tc class add dev eth0 parent 1:0 classid 1:1 htb rate 100Mbit
ceil 100Mbit
defaulthost ~ #
defaulthost ~ # tc class add dev eth0 parent 1:1 classid 1:2 htb rate 100Mbit
ceil 100Mbit
defaulthost ~ # tc qdisc add dev eth0 parent 1:2 handle 2: pfifo limit 1000
defaulthost ~ #
defaulthost ~ #
defaulthost ~ # tc filter add dev eth0 pref 200 parent 1: protocol ip u32
match ip src 1.1.1.1/32 flowid 1:1 action skbedit priority 10
defaulthost ~ # tc filter add dev eth0 pref 201 parent 1: protocol ip u32
match ip src 1.1.1.2/32 flowid 1:2 action skbedit priority 11
RTNETLINK answers: File exists
We have an error talking to the kernel
As soon as skbedit involved, i am getting this strange result "File exists".
If i change(remove) flowid, classes - seems doesn't matter
Result looks like this:
defaulthost ~ # tc -s filter show dev eth0
filter parent 1: protocol ip pref 200 u32
filter parent 1: protocol ip pref 200 u32 fh 800: ht divisor 1
filter parent 1: protocol ip pref 200 u32 fh 800::800 order 2048 key ht 800
bkt 0 flowid 1:1 (rule hit 460 success 0)
match 01010101/ffffffff at 12 (success 0 )
action order 1: skbedit priority :10 installed 82 sec used 82 sec
Action statistics:
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
filter parent 1: protocol ip pref 201 u32
filter parent 1: protocol ip pref 201 u32 fh 801: ht divisor 1
If i remove skbedit:
defaulthost ~ # tc filter add dev eth0 pref 200 parent 1: protocol ip u32
match ip src 1.1.1.1/32 flowid 1:1
defaulthost ~ #
