3.1.4.3 Unauthorized MAC sharing connection with authorized MAC
Figure 5: Example 1; unauthorized MAC sharing connection with authorized MAC
The unauthorized device is not able to send any traffic into the network but station with IP 30.0.0.2 can
still talk to the network. However the unauthorized device is still able to see broadcast and unknown traffic
flowing in the VLAN and, if a shared hub was inserted on the network connection, it can also see all of
traffic sent and received by station with IP 30.0.0.2; if this is undesired the MAC Security should be
configured to partition the port upon an access violation.
