In the given scenario, to send user traffic to a packet capture tool for troubleshooting, Remote SPAN (RSPAN) should be utilized. RSPAN allows traffic monitoring on one switch to be monitored by a RSPAN VLAN that is available on another switch. In this case, defining the remote span VLAN on both switches SW1 and SW2 allows the 172.16.2.0 /24 user traffic to be captured and analyzed remotely.
