The output shows that the upper traffic threshold has not been exceeded. All traffic is transmitted through
the primary interface GigabitEthernet 2/0/1.
# Verify that both backup interfaces are in STANDBY state because the upper threshold has not been
exceeded.

# Increase the incoming or outgoing traffic rate to be higher than 8000 kbps (80% of the specified
bandwidth) on the primary interface. (Details not shown.)
# Verify that the backup interface GigabitEthernet 2/0/2 comes up to participate in traffic forwarding,
because it has higher priority than GigabitEthernet 2/0/3.
