Hi Guys,

I'm using Debian 8.8.0 and trying to simulate a bidirectional packet loss over bridge interface and while I was at it, I found packet loss didn't work on the latest bridge-utils-1.5.9. Is this some known limitation(work to be done later)?

[IP traffic tester]-->eth0[Debian]eth1<--[IP traffic tester]


Q1)

# tc qdisc add dev br0 root netem loss 1% # this command is accepted but no packet loss is observed.


Of-course, a physical interface one works just fine.

# tc qdisc add dev eth0 root netem loss 1%
# tc qdisc add dev eth1 root netem loss 1%

Q2)

Also, I'm trying to simulate a burst(consecutive) packet loss by:


# tc qdisc add dev eth0(or eth1) root netem loss 3% 100% # this command is accepted but no packet loss is observed, either.


Should I look for other document sources specific to Debian or post this in a different forum?

Thanks for any input.

If interface is in normal mode, such as routing mode, does tc qdisk loss work?
