Configuring HDLC encapsulation |
The default encapsulation method used by
Cisco devices on synchronous serial lines is Cisco HDLC. If the serial interface is
configured with another encapsulation protocol, and the encapsulation
must be changed back to HDLC, enter the interface configuration mode
of the serial interface. Then enter the
encapsulation hdlc
command to specify the encapsulation protocol on the interface.
 Cisco HDLC is a point-to-point protocol that can be used on leased lines between two Cisco devices. When communicating with a non-Cisco device, synchronous PPP is a more viable option.
