Configuring the SM-1T3/E3 Service Module
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:
the encapsulation method, use the following commands:
SUMMARY STEPS
1.
enable
2.
configure terminal
3.
interface serial slot/subslot/port
4.
encapsulation encapsulation-type {hdlc | ppp | frame-relay}

Example:
Router> enable
Enables privileged EXEC mode.
•
Enter the password if prompted.
Step 2

Router(config-if)# encapsulation ppp
Sets the encapsulation type on the interface:
•
hdlc—High-Level Data Link Control (HDLC)
protocol for serial interface. This
encapsulation method provides the
synchronous framing and error detection
functions of HDLC without windowing or
retransmission. This is the default for
synchronous serial interfaces.
