720CHAPTER 51: CONFIGURING DCC

Table 753 Create a Dialer Bundle and Assigning the Physical Interfaces to it

Operation	Command
Add a physical interface to the specified	dialer bundle-member number [
dialer bundle	priority priority ]
Delete the physical interface from the	undo dialer bundle-member number
dialer bundle

By default, no dialer bundle is created, and the physical interfaces do not belong to any dialer bundle. If a physical interface is assigned to a dialer bundle, a default priority of 1 is assigned.

Configuring dialing authentication for resource-shared DCC

To implement the resource-shared DCC, the called party must identify the calling parties through authentication through the communications between the physical interfaces and the dialer interfaces. Therefore, PAP or CHAP authentication must be configured.

Use the dialer user command in dialer interface view then use the local-user password command in the system view to perform other configuration steps in dial interface (physical or dialer interface) view.

Table 754 Configure Multiple Interfaces to Receive Calls From Multiple Remote Ends

Operation	Command
Configure the remote user name	dialer user username
Delete the remote user name	undo dialer user
Configure the link layer protocol to PPP	link-protocol ppp
Configure an authentication mode	ppp authentication-mode { pap chap
	}
Configure the interface to send the local	ppp pap local-user username password
user name and password for PAP	{ cipher simple } password
authentication
Configure the user name that the local	ppp chap user username
end will send to the remote end for CHAP
authentication
Configure the password that the local end	ppp chap password { cipher simple }
will send to the remote end for CHAP	password
authentication
Configure the user name and password	local-user username password { cipher
that the remote end is allowed to dial in	simple } password

The users are recommended to configure either PAP or CHAP authentication on both the physical and dialer interfaces of both sender and receiver.

When PPP is encapsulated on a Dialer interface, the remote user name gained through PPP authentication procedure will determine the Dialer interface for receiving calls, then the command dialer user is a must and the command dialer number is optional. While Frame Relay is encapsulated on a Dialer interface, because of no username negotiation procedure, the called end will distinguish Dialer interfaces according to the received number dialed by calling end, hence the command dialer user is optional and the command dialer number is a must.
