[j-nsp] Arbor Peakflow with MX960

[Matt Hite]

Hello --

I've recently deployed some MX960 (Treo) and now need to get their
flow data in Arbor Peakflow SP. Unfortunately the instructions in the
Arbor manual appear to be very long in the tooth and a bit confusing.
Specifically, the integration directions are for a "JunOS version
5.5B1.3 on a Juniper M5 Router." Now I'm sure there is carry over that
is relevant still, I just want to make sure I'm going down the right
path. Apologies for the rudimentary questions here. My previous
experience was sflow only...

They mention using "set forwarding- options family inet filter input
filter <name>" as "the easiest way to apply a filter to all packets
received by the system."

They then suggest a filter like this:

admin at m5# set firewall filter cflowd term sampled_packets from
source-address 0.0.0.0/0
admin at m5# set firewall filter cflowd term sampled_packets then accept
admin at m5# set firewall filter cflowd term other then accept

To make things a bit confusing, they also say to enable it on an interface:

set interfaces e3/4/1 unit 0 family inet filter input cflowd

I'm guessing you would do it on the interface or do it globally with
the "set forwarding- options family inet filter input filter <name>"
command? Confused a bit by this...

Also, since I have other filters on the input side of my interfaces, I
presume I'd remove that last term "other" from their example. Although
I'm a bit concerned that dropping that on the input filter for the
interface will act as a terminating action in the evaluation of
packets flowing through the interface, and it won't continue on with
my other terms.

I also see some mention in the Juniper CLI manual about how to do it
if you have a Monitoring Services PIC:

Also, Arbor provides some instructions on configuring version 9 cflow,
too, although I don't think that's actually what I need to do.

Does anyone have a similar setup who might be willing to help me out
with an annotated example? It would be very much appreciated.

Thanks,
