Hello
Did you try only input direction? I guess yes and i guess it works but just to
be sure. I
Netflow v5 & 12.3 work fine for us on dpc but we use only input sampling.

Dear all,
I have a very curious problem with some box running
JunOS 12.3, DPC-based:
I have one interface towards some upstream provider and want to
generate cflow for in- and outbound direction and have the following
configuriation:
teichhorn@somerouter# show forwarding-options
sampling {
input {
rate 2048;
run-length 0;
max-packets-per-second 4096;
}
family inet {
output {
flow-active-timeout 60;
flow-server a.a.a.a {
port 9000;
autonomous-system-type origin;
source-address (ip lo0);
version 5;
}
}
}
}
teichhorn@somerouter# show interfaces xe-0/3/0
description "TRANSIT - XXX";
unit 0 {
family inet {
sampling {
input;
output;
}
address c.c.c.c;
}
family inet6 {
address a:b:c:d::1/128;
}
}
(It doesn't matter if I use family inet sampling or a firewall filter)
All the flows which are exported only contains the outbound packets,
but no inbound ones.
Has anyone seen that before or has a hint? I would like to open a case
the next days but like to hear your opinion before...
(And no, I can't simply put output sampling on the other interfaces,
since there is MPLS forwarding on them active...)
Thanks,
Tom
