Hello,
I'm facing out of sequence errors, when I transmit traffic
from source to destination through my netem configured box(router).
I want to emulate delay by filtering traffic based on SRCIP and DESTIP
Below is my setup
+-----+ +-----+ +-----+
| | iface1---------eth0 | | eth1------------iface2| |
+-----+ +-----+ +-----+
source netem configured box(router) destination
iface1 ip: 10.0.0.10 gw 10.0.0.1
iface2 ip: 20.0.0.10 gw 20.0.0.1
eth0 : 10.0.0.1
eth2 : 20.0.0.1
Below are the commands i used on eth0 and eth1 to emulate delay
tc qdisc add dev INFACE root handle 1: htb default 10
tc class add dev INFACE parent 1: classid 1:1 htb rate $RATE ceil
10000mbit
tc class add dev INFACE parent 1:1 classid 1:11 htb rate $RATE ceil
10000mbit
tc qdisc add dev INFACE parent 1:11 handle 11:0 netem delay 10ms
limit 100000
IFACE: eth0 and eth1
Below command is to filter the traffic
iptables -t mangle -A POSTROUTING -s 10.0.0.10 -d 20.0.0.10 -j
CLASSIFY --set-class 1:11
when i send traffic through iperf3 from source to destination it
applies the desired delay, but with OUT OF ORDER errors
iperf3 commands:
source
iperf3 -c 20.0.0.10 -i 1 -u -b 10g (sending traffic)
destination
iperf3 -s (reciving out of order errors)
Note: I'm using 10g NIC
Let me if im doing anything wrong.
