722 CHAPTER 51: CONFIGURING DCC
Configuring MP binding in resource-shared DCC
If an interface is a serial, asynchronous interface or an AUX interface, then the
resource-shared DCC will enable another physical interface in the dialer bundle of
the dialer interface whenever the percentage of traffic on the physical interface to
the bandwidth exceeds the traffic threshold. At the same time, it implements MP
binding on these links. If the physical interface is an ISDN BRI or PRI interface, the
resource-shared DCC will first select the available B channels on the interface, and
then the B channels on other ISDN interfaces to implement MP binding.
Use the link-protocol ppp or ppp mp command to configure PPP encapsulation
and MP binding in dial interface (physical or dialer interface) view, and use the
dialer threshold command to configure a traffic-percentage threshold for MP
binding in dialer interface view.
Table 756 Configure MP Binding in Resource-Shared DCC
By default, neither MP binding, nor traffic-percentage threshold is configured.
That is, MP binding is not supported.
Configuring PPP
Callback
When configuring PPP callback, one endpoint of a connection should be
configured as client, and the other endpoint as server. The calling party is the
callback client and the called party is the callback server. The client first originates
a call, and the server determines whether to originate a return call. If it determines
to do that, the callback server disconnects and then originates a return call
according to the information such as user name or callback number.
Configure PPP callback after completing the basic configuration of Circular DCC or
Resource-Shared DCC.
PPP callback implementation requires authentication. The users are recommended
to configure PAP or CHAP authentication on both the physical and dialer interfaces
on both the callback client and server.
Configuring PPP callback in the circular DCC implementation
1 Configure PPP callback client in the circular DCC implementation
As a callback client, a router can originate calls to the remote end (which can be a
router or Windows NT server having the PPP callback server function), and receive
the return calls from the remote end.
Use the local-user password command to configure the user name in system
view, and perform the other configurations in dial interface (physical or dialer
interface) view.
