is displayed in the traffic diagram below the traffic-flow display controls.

Ethernet 0 and exiting on the router interface Serial 0, fol low these steps:
Step1 Choose Ethernet 0 in the From drop-down list.
Step2 Choose Serial 0 in the To drop-down list.
Step3 Click Go.
Step4 To switch the interfaces in the From and To drop-down lists, choose Swap From
and To interface from the View Option drop-down list.

the traffic diagram, see Examine the Traffic Diagram and Choose a Traffic
Direction.
