Giuliano,

So how does the arp test work please?
Is it trying to ping your Juniper box (AEx ip) but using different source MAC 
address for every ping please? (doing 1200 ping => 1200 source macs)
Or more likely
Is it trying to ping your Juniper box (AEx ip) but using same source MAC 
address for every ping where each ping has a unique source IP please?

So the connection is operational as 80 pings came across just fine right?

Adam,
Sorry about delay to answer this post.
We are trying to connect our JUNIPER MX960 router to a IX (Internet Exchange 
Point).
Once you are connected for the first time, the guys from the IX did a simple 
test (linux script) .. similar to an limited ARP Spoofing on every single 
physical port to evaluate the number of MAC answers supported for the router 
(minimum accepted is 1200). They will connect you to L2 main matrix.
We have another board on this router ... same MPC4E with 32 x 10G SFPP 
interfaces.  When we did the same ARP Spoofing test using a LAG with 8 x 10G 
interfaces ... it works fine.
With the new MPC4E board (2 x 100G + 8 x 10G SFPP) the test is not working. The 
100G (et-x/x/x) interface configured inside an AEx logical interface does not 
answer more than 80 MACs ...

We did every single configuration possible on this board ... but nothing is 
working.
The router learns the 1200 MACs ... but the answer does not return to the pc 
machine tester.

I was thinking about some special configuration for this board to do it to 
work. JUNIPER said that there is not any special configuration needed.
Today we will do a simple test using ettercap and a switch with 10G connections 
directly to the new board to see if we got something different.

Thanks a lot,

Giuliano

Hello Giuliano,

I somehow did not get what is not working exactly?
Are the ports not coming up? Is the LACP not coming up? Or you can't pass 
frames between the VLANs?
