Step 2 Set the mode of clock source selection on Switch B.
# On Switch B, set the priority of the clock signal that GigabitEthernet 5/0/7 sends from the right
side of the frame to 10, and set priority of the clock signal that GigabitEthernet 5/0/3 sends from
the right side of the frame to 20. Retain the default WTR time. Set the priority of the clock signal
sent from the right side of the frame to 6.
