I guess I will just try some options and see what works. Here is one of the options (Basic):
set interfaces xe-1/0/0 unit 0 family ethernet-switching
set interfaces xe-1/1/0 unit 0 family ethernet-switching
set forwarding-options analyzer test-monitor input ingress interface xe-1/0/0
set forwarding-options analyzer test-monitor input egress interface xe-1/0/0
set forwarding-options analyzer test-monitor output interface xe-1/1/0
This will or should, give me the basics..... will let you know
