After you have configured the desired PPP interfaces for WAN boards, you should configure one or more WAN call destinations as described in How to Configure a WAN Call Destination for a Permanent PPP Connection.
Before you begin, you must complete the following tasks:
To configure a WAN call destination for a permanent PPP connection, complete the following steps:
Load NIASCFG, then select the following parameter path:
Select Configure NIAS > Protocols and Routing > WAN Call Directory
Press Ins to configure a new WAN call destination.
The prompt New Call Destination Name , allows you to enter a name of up to 47 alphanumeric characters for the new WAN call destination.
The WAN call destination name entered here is used in several other menu options when a WAN call destination name needs to be identified. You should use a descriptive name, such as the name of the remote destination or a branch or store number.
Enter a name for the new WAN call destination.
A list of supported wide area media is displayed. These are media available on previously configured interfaces.
Select PPP as the wide area medium.
The PPP Call Destination Configuration menu is displayed. The Call Type selection is highlighted. This selection specifies the type of connection to be made: permanent (continuously active) or on-demand (when activated by the presence of data traffic to the remote peer).
Ensure the call type is set to Permanent (the default).
This sets a WAN call destination for permanent calling through the specified interface.
Select Interface Name , then select an interface name from the pop-up menu.
This field allows you to select the name of the configured WAN interface through which this WAN call destination can be accessed.
For the Telephone Number field, do one of the following:
If you are using a dial-up line or V.25bis (but not DTR-controlled dialing), specify a telephone number.
The ASCII string you enter in the Telephone Number field can be up to 32 alphanumeric characters. This string is used by device (modem) management when initiating the outbound call to this destination.
If you are using a dial-up line with DTR-controlled dialing, leave this parameter blank.
The DTR-controlled device should have been configured with the telephone number offline, as specified by the modem manufacturer.
If you are using a leased line, leave this parameter blank.
Select Outbound Authentication , then select the appropriate authentication option from the pop-up menu.
This lets you specify the authentication protocol to use for an outbound connection. You can disable authentication for a permanent call if the remote system does not require either authentication type.
You can choose from the following options:
NOTE: If you choose Either PAP or CHAP , PPP will provide CHAP authentication if CHAP is requested or will provide PAP authentication if PAP is requested.
Select Password , then enter a password of up to 47 alphanumeric characters.
NOTE: This field is case-sensitive.
The value specified in this field must be the PAP password (or the CHAP secret value) expected by the remote peer during the PPP authentication. If Outbound Authentication is set to anything other than None , then a password must be specified; this field cannot be left blank.
For the WAN call destination to succeed, this password and the local system ID must also be configured in the inbound authentication database of the called router.
Select Local System ID , then enter a local system ID of up to 47 alphanumeric characters.
NOTE: This field is case-sensitive.
During outbound authentication, this name is sent to the remote system to identify the local system for authentication and connection purposes. The default value is the local system server name.
Select Remote System ID , then enter a remote system ID of up to 47 alphanumeric characters.
NOTE: NetWare server names should be all uppercase. TCP/IP hostnames are usually lowercase.
This field allows you to specify the name of the remote peer associated with this WAN call destination. Typically, this name is the remote system server name. By default, the Remote System ID is blank.
Leave all other parameters in the PPP Call Destination Configuration menu at their default values. For a complete discussion of the other parameters in this menu, refer to the appropriate topics in this section for detailed information.
If the media type is ISDN, select ISDN Parameters and configure the following parameters as needed.
Select Remote Address and enter the telephone number of the destination of the call.
This field must be configured if you are using ISDN.
If your service provider requires a destination subaddress (usually a telephone extension number), select Remote Sub-Address and enter the desired number.
Your service provider might not require a subaddress to be configured. Contact your service provider for more information.
If your service provider requires a local subaddress (usually a telephone extension number), select Local Sub-Address and enter the desired number.
The local subaddress is assigned by your ISDN service provider and might not be required. Contact your service provider for details. The default is the value you configured under Network Interfaces .
Select ISDN Call Rate and select a rate of 56 Kbps, 56 Kbps over voice, or 64 Kbps.
Contact your service provider for this information.
Press Esc .
Select Special Options and configure the following parameters as needed.
If the remote system requires a login script and the medium is not ISDN, select Login Script Name and select the desired login script from the list of supported scripts or enter the values for the parameters required by the login script, such as the username, password, and so on. Login scripts are not supported for ISDN.
To update the inbound authentication database so that the interface associated with this WAN call destination reflects the connection information entered here, select Inbound Authentication Update and select Enabled .
Press Esc until you return to the Internetworking Configuration menu; save your changes when prompted.
If prompted, select Yes to synchronize the inbound authentication database.
The inbound authentication database is made to agree with the outbound call authentication parameters in this WAN call destination configuration. This is useful if you expect to receive calls from systems you make calls to.
The WAN call destination you configured is listed in the Configured WAN Call Destinations screen.
To configure another WAN call destination, repeat Step 2 through Step 16 .
If you want these changes to take effect immediately, select Reinitialize System .
If you want to configure other parameters, do so now, then reinitialize the system when you are finished.
If you want to further customize and optimize your connection, refer to the appropriate topics in this section for detailed information about the following parameters:
Before your WAN connection works, you must also complete the following tasks:
For information about these two tasks, refer to "Setting Up" in the appropriate protocol documentation.
