The corner case for QFX3500 is that it is still the only Juniper switch
with native FC support, though most others have good FCoE transport support.

Hi,
So I’m still a bit confused on what can or can’t be used in the flow
monitoring processes. In this case I have an SRX 3600 with a routing instance.
I found a config example that illustrates how to enable flow sampling in this
type of environment. It specifically mentions that you
This is platform-dependent. Some platforms (definitely EX, probably SRX)
use the RE for processing flow data--so you can use fxp0. Other platforms
(MX) use the PFE, which is why fxp0 is not a valid interface.
I did some testing on this a few months ago to confirm that EX switches (at
least
This makes sense to me. Thanks for such a good response I really feel like I
have a better bead on this now.
Thanks

No problem.
Just keep in mind that with the RE processing flow data, you can quickly
kill your RE if your sampling rate is too low. 1:1 sampling with the MX
isn't as problematic since it's processed by the PFE.

So the interesting thing is I had opened a ticket to ask this same question and
I got a totally opposite answer.:)
I guess the best thing to do here is after hours today test out the config and
see how it goes. Else spin up another 3600 in the lab and give it a run
through. Your answer makes
Yeah. Maybe the SRX3600 (and all high-end SRX) is a bit different, but I'm
pretty sure when we tested the SRX550 (branch) it was handled by the RE.
I just checked an SRX1400 (high end/data center), and the RE is
definitely handling the flow traffic. This may be due to the way I have it
I wanted to follow-up on the list with a report of what I did to try to
resolve this issue.
I have not had the opportunity to try to play tricks with routing policy
to only populate the forwarding table with a default router while still
receiving a full Internet router table via BGP. It is a
+1 regarding input on VCF
Does anyone have any practical experience with a VCF either mixed-mode or
not? We're evaluating it as a replacement for legacy 6509s. Cisco is
pitching a Nexus 6004 + FEX solution.
