Configuration Tasks

Configuring Encapsulation

When traffic crosses a WAN link, the connection needs a Layer 2 protocol to encapsulate traffic. To set the encapsulation method, use the following commands:

Command	Purpose
Router# configure terminal	Enters global configuration mode.
Router(config)# interface serial slot/subslot/port	Selects the interface to configure.
	• slot/subslot/port— Specifies the location of the
	interface. See the: “Specifying the Interface
	Address on a SPA” section on page 13-5
Router(config-if)#encapsulation {hdlc ppp	Sets the encapsulation method on the interface.
frame-relay}	• hdlc—High-Level Data Link Control (HDLC)
	protocol for serial interface. This is the
	default.
	• ppp—PPP (for serial interface).
	• frame-relay—Frame Relay (for serial
	interface).

Verifying Encapsulation

Use the show interfaces command to display the encapsulation method:

router# show interfaces serial 6/0/1 Serial6/0/1 is up, line protocol is up
