Mux is sending broadcast

Two days spent in troubleshooting a point to point link with lot of hops between them. I stumble to see one weird thing that whenever the mux sfp port is connected to the router, the router card starts rebooting. This is the case not with a single router but with the multiple ones. We changed everything but all in vein. At last we able to catch a little point about mux which is using layer 2 switching and forwarding vlans traffic to the router directly. The broadcast was so huge which forces routes card to halt.

How were you able to identify the traffic when the router started rebooting? Was there any thing changed before this symptom started?
