I am testing to ensure line rate traffic run for N days between Juniper and the System Under Test is stable/error free and I want to not introduce a dedicated traffic generator (Ixia/Spirent/Etc...). The idea is to generate a handful of frames from the System Under Test using the broadcom tool and the storm those same frames between all interfaces under test for N days.
Scenario:
SUT Port A ----> Port A MX480 Port B MX480 ----> Port B SUT
Note SUT is the same system in the same forwarding domain (vlan 1600)
Question: is there a way to enable Juniper Mx480 ports to be a 'dumb pass through' for a storm? I have my config below which uses bridge domains for vlan switching.
The problem I am having is that the Juniper interface seems to be dropping duplicate SA's and detecting the storm before it starts (theory at this point)
So far what I’m seeing is that one of the two interfaces is dropping the traffic at the interface level;

I’m curious why the input packet rejects doesn’t indicate SA or DA rejects?
Configuration
# add interfaces to the bridge domain
set interfaces et-5/0/2 vlan-tagging
set interfaces et-5/0/2 encapsulation extended-vlan-bridge
set interfaces et-5/0/2 unit 100 vlan-id 100
set interfaces et-5/0/5 vlan-tagging

Any ideas, possible solutions, or even suggestions would be appreciated. Thank you in advance
