link-protocol x25
Syntax	link-protocol x25 [ dce dte ] [ ietf nonstandard ]
View	Interface view
Parameter	dce: Specifies the DCE mode.
	dte: Specifies the DTE mode.
	letf: Encapsulates IP or other network protocols on the X.25 network based on
	the standard stipulation of the IETF RFC 1356.
	nonstandard: Nonstandard encapsulates IP or other network protocols on the
	X.25 network.
Description	Use the link-protocol x25 command to encapsulate X.25 protocol on the
	specified interface.
	By default, the link-layer protocol for the interface is PPP. When the interface uses
	X.25 protocol, it works in DTE IETF mode by default.
	Note that:
	When two Routers are connected via the X.25 public packet network, they shall
	work as DTE and use IETF format.
	If two Routers are directly connected, one Router shall work as DTE, the other as
	DCE. Both parties should use the same data format.
	If the X.25 switching function is used, the device should work as DCE.
	In practice, select the IETF format if there is no special requirement.
Example	# Specify X.25 as the link layer protocol of the interface Serial2/0 that works in
	DTE IETF mode.
