Configuring Bulk Services > Creating PPP/ATM Service Type

Creating PPP/ATM Service Type

The PPP/ATM service builds on the ATM protocol stack.

To create the PPP/ATM service type:

1. When the Service Type dialog box appears, select PPP/ATM Service.
2. Click Next.

The PPP Interface dialog box appears.

3. Set the PPP interface parameters (Table 58).

 Table 58:  PPP Interface Parameters 

 Parameter
 Description

 Name

 Identifies the interface; generated automatically


 Alias

 Description of the interface; 0-15 characters; default: blank


 IfIndex

 Identifies the interface on the particular line interface; generated automatically


 Operational

 Current operational status of the interface


 Administrative

 Desired status of the interface: Up/Down; default: Up


 Profile

 Profile that you want to associate with this interface. Click 
to open the Associate Profile dialog box. 


 DNS Address Peer Precedence

 Indicates which value takes precedence when the E-series router and the PPP peer system have the primary and secondary Domain Name System (DNS) name server addresses configured with different values.


 WINS Address Peer Precedence

 Indicates which value takes precedence when the E-series router and the PPP peer system have the primary and secondary Windows Internet Name System (WINS) name server addresses configured with different values.


 LCP Config

 Magic Number Enabled

 Randomly generated number used to identify one end of a point-to-point connection. LCP (Link Control Protocol) magic number support is available on all serial interfaces. PPP always attempts to negotiate for magic numbers, which are used to detect looped-back lines. The router might shut down a link if it detects a loop.


  Initial MRU

 LCP on maximum receive unit must be within the following ranges:

  
 POS interface—64-4466
  
 DS0 bundle—64-1596
  
 ATM subinterface—64-9178
  
 PPPoE subinterface—64-1492



 Keepalive Timeout (sec)

 Keepalive tracks the status of the connection. The timeout period is set in the range 30-300 seconds for high-density mode (for example, when PPP is layered over PPPoE or ATM subinterfaces) and 10-300 seconds for low-density mode (when PPP is layered over POS or a DS0 bundle). The default is 30 seconds.


 Authentication

 Type

 Authentication method chosen to verify access to the interface. Choose from the drop-down list.

  
 None—No authentication method specified
  
 pap—Specifies PAP (Password Authentication Protocol) as primary authentication protocol
  
 chap—Specifies CHAP (Challenge Handshake Authentication Protocol) as primary authentication protocol
  
 papChap—Specifies PAP as primary authentication protocol and CHAP as the alternate
  
 chapPap—Specifies CHAP as primary authentication protocol and PAP as the alternate



 Max Authen Retries

 Number of times a user can fail to enter the correct login information (username and password) to gain access

7. Set the IP address parameters. (See Table 54 on 175.)

Several of the parameters are supported by related dialog boxes that you access by clicking either or .

NOTE: The IP address that you created is the IP address of the ATM subinterface.

8. Click Next.

A summary of the PPP service configuration appears.
