Furthermore, a failover event would cause additional loss of connectivity. Consider a cable
disconnect on the Top Switch port 4. In this case, Gray would send the ICMP Request to Red 49:C9,
but because the Bottom switch has no entry for 49:C9 in its CAM Table, the frame is flooded to all its
ports but cannot find a way to get to 49:C9.

The addition of a link between the switches allows traffic from/to Blue and Gray to reach each other
without any problems. Note the additional entries in the CAM table for both switches. The link
interconnect is critical for the proper operation of the team. As a result, it is highly advisable to have
a link aggregation trunk to interconnect the two switches to ensure high availability for the
connection.
