Figure 5: Teaming Across Switches Without an Interswitch Link
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.
