Ppp Callback - HP MSR series Command Reference Manual

Therefore, authentication must be configured on these physical interfaces, so as to use the username of
a dial-in party to locate the corresponding dialer interface for the call. In this mode, physical interfaces
and dialer interfaces are dynamically bound. Furthermore, a dialer interface can only call a destination
address as specified in the dialer number command.
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.
Examples
# Create dialer interface Dialer 1.
<Sysname> system-view
[Sysname] interface dialer 1

ppp callback

Use ppp callback to specify the interface as the server or client to send or accept PPP callback requests.
Use undo ppp callback to disable the interface as the PPP callback server or client.
Syntax
ppp callback { client | server }
undo ppp callback { client | server }
Default
Callback is disabled.
Views
Dialup interface (physical or dialer interface) view
Default command level
2: System level
Parameters
client: Sends callback requests as the PPP callback client.
server: Accepts callback requests as the PPP callback server.
Usage guidelines
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.
Examples
# 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
