334CHAPTER 20: DCC CONFIGURATION COMMANDS

The physical interfaces in C-DCC and Resource-Shared DCC do not use individual network addresses. Instead, they use the addresses of the corresponding dialer interfaces.

In both C-DCC and RS-DCC, physical interfaces use the network addresses of their associated dialer interface rather than being assigned separate addresses.

Example # Create dialer interface Dialer1.

<Sysname> system-view [Sysname] interface dialer 1

ppp callback

Syntax	ppp callback { client server }
	undo ppp callback { client server }
View	Dial interface (physical or dialer) view
Parameter	client: Sends callback requests as the PPP callback client.
	server: Accepts callback requests as the PPP callback server.
Description	Use the ppp callback command to specify the interface as the server or client to
	send or accept PPP callback requests.
	Use the undo ppp callback command to disable the interface as the PPP
	callback server or client.
	By default, callback is disabled.
	PPP callback adopts the client/server model where the calling party is the callback
	client and the called party is the callback server. The client first originates a call,
	and the server decides whether to originate a return call. If a return call is needed,
	the callback server disconnects and then originates a return call according to the
	information such as username or callback number.
	This is useful for saving cost in the case that the call rates in two directions are
	different.
Example	# Configure interface Serial 2/0 as the PPP callback server to accept callback
	requests.
	<Sysname> system-view
	[Sysname] interface serial 2/0
	[Sysname-Serial2/0] ppp callback server
