how does the traffic appear in SmartView Tracker?

Consider the following scenario: A hub connects four hosts a VLAN-Tagged port on a switch. The hosts have IP addresses ranging from 10.0.0.1 to 10.0.0.4. The switch adds a VLAN Tag of 400 to all communication passing through it. Once communication from the second host on the hub passes through the switch port on the way to its destination on the external network, how does the traffic appear in SmartView Tracker? Assume that traffic enters the Gateway on interface eth3.
