• If no slot/port numbers are entered, collision information for all slots/ports on the switch is displayed.

• You can display a specific interface by entering the slot and port number (e.g., 3/1).

• You can display a range of port numbers (e.g., 3/1-4).

• You can display all interfaces in a slot by entering the slot number (e.g., 3).
