Up until this point we have created traffic mirror target - mirrored traffic is send to target, traffic mirror filter - we created a filter with inbound rule to mirror port 80 traffic. Now we will create traffic mirror session. Traffic mirror session sends mirrored packets from the source to a target so that you can monitor and analyze traffic.


1. Launch Amazon VPC console in the region where you have created your [target](/030_module1/createtarget/) and [filter](/030_module1/createfilter/):
