After you have configured a NetWare Link/X.25 board, as described in Setting Up in the Boards documentation, you need to configure an X.25 network interface.
Before you begin, make sure you have planned your X.25 network. Refer to Planning for X.25 checkpoints and planning information.
To configure network interface parameters for NetWare Link/X.25, complete the following steps:
Load NIASCFG, then select the following parameter path:
Select Configure NIAS > Protocols and Routing > Network Interfaces
Select an unconfigured port on a WAN interface board, then press Enter.
The Select A Medium screen is displayed.
Select X.25-Host, then press Enter.
The X.25 Network Interface configuration menu is displayed. The cursor is positioned in the Profile field, but you should first consider the information in the two fields that precede it.
The Interface Name field is a read-only field. It displays an interface name that is a combination of the board name defined in the Board Configuration menu, underline characters used as separators, and a port number (typically 1 through 4).
The Interface Group field initially displays a value of None. You can use this field to assign this interface to a defined group of WAN interfaces. WAN call destinations can be configured to use interface groups, which allow protocols such as the IP or Internetwork Packet ExchangeTM (IPXTM) protocols to request that an on-demand X.25 virtual circuit be made through any available interface within the group. The interface actually used for the call is determined at the time the call is made.
If you decide to assign this interface to a group, select the Interface Group field, then press F3 or Enter to display a list of configured groups.
Select an interface group from the list, then press Enter, or press Ins to create a new interface group.
All network interfaces in a group must have the same configuration characteristics.
In the Interface Status field, accept Enabled by pressing the Down-arrow key to skip to the next field, or press Enter to select Disabled from a pop-up menu.
This field is most often used to test a particular board configuration by disabling other boards, which prevents them from loading.
In the Profile field, press Enter to display a list of standard profiles for X.25 service providers.
Select the standard profile for your X.25 service provider from the list, then press Enter to use the values in the standard profile, or press F2 to make a copy of the profile.
We recommend that you use the standard profiles whenever possible. Standard profiles are read-only; you cannot modify the values in them.
You can modify the values in a copy of a standard profile to match any custom requirements imposed by your local X.25 network service provider. If you make a copy of a standard profile, you must give the copy a unique (local) name.
If you make a copy of a standard profile and you need to modify the values assigned to one or more parameters, press Ins or F3 to display the X.25 Profile Configuration menu and access menus for the following:
The parameters found in these menus correspond to many of the fields found on the NetWare Link/X.25 Network Access Worksheet. Refer to Planning for detailed information about setting the values of these parameters.
In the Local DTE Address field, enter the address assigned by your local X.25 network service provider, then press Enter.
NOTE: You can exit the configuration at this point by accepting the default values for the remaining parameters. To save this configuration and return to the Internetworking Configuration menu, press Esc, select Yes when prompted, then press Enter. Otherwise, continue with Step 11.
In the Statistics Period field, accept the default value or enter a new value.
This value specifies the interval, in seconds, at which the interface board is polled by the driver to gather statistical data. The range of values is 1 to 1,024 seconds; the default value is 1 second.
In the User Data Size field, accept the default value or enter a new value.
This value specifies the maximum user data size, in bytes, that the interface supports. The range of values is 500 to 4,096 bytes; the default value is 1,500 bytes.
In the Interface Queue Limit field, accept the default value shown or enter a new value.
This value specifies the maximum number of data packets that can be queued to this port. The range of values is 0 (unlimited) through 1,024 packets. The default value is 100 packets.
The Interface Queue Limit value should be less than the configured Maximum Packet Receive Buffers value.
In the Physical Options field, press Enter to view or modify the following parameters:
Press Esc to return to the X.25 Network Interface menu.
In the Authentication Options field, press Enter to view or modify the X.25 authentication options.
The X.25 Authentication Options menu is displayed. The Interface Name field is a read-only field. It displays an interface name that is a combination of the board name defined in the Board Configuration menu, underline characters used as separators, and a port number (typically 1 through 4).
In the Inbound Authentication field, accept the default value, Disabled, by pressing the Down-arrow key to skip to the next field, or press Enter to select Enabled from a pop-up menu.
The setting of this parameter specifies whether incoming calls are subject to authentication. If you cannot control access to this X.25 interface, you should enable authentication.
If Inbound Authentication is set to Enabled, only incoming calls with a DTE address specified in the authentication database are accepted.
If Inbound Authentication is set to Disabled, the interface will accept all inbound calls.
NOTE: If Inbound Authentication is set to Disabled, the values of the other parameters in this menu are irrelevant. To return to the Internetworking Configuration menu, press Esc and skip to Step 22. Otherwise, continue with Step 18.
In the Authentication Database Name field, accept the name shown or enter a new name, then press Enter.
This field allows you to enter the name of an existing authentication database or supply the name for a new authentication database.
In the Authentication Database field, press Enter to view or modify the entries in the authentication database specified in the previous field.
The X.25 Inbound Authentication Database screen displays a list of currently defined valid partners and their DTE addresses. If this is a new database, the list will be empty.
You can add new entries, or you can edit or delete existing entries.
To add a new entry to an authentication database, press Ins. To edit an existing entry, select the entry and press Enter.
In either case, the X.25 Inbound Authentication Entry menu is displayed. The Interface Name field is a read-only field. It displays an interface name that is a combination of the board name defined in the Board Configuration screen, underline characters used as separators, and a port number (typically 1 through 4).
The Database Name field is also a read-only field. It displays the database name that you specified in Step 18.
In the Remote System ID field, press Enter to display a list of existing remote system IDs. With the list displayed, press Ins to enter a new ID or Del. to delete an existing ID.
The Remote System ID parameter specifies the local handle for a partner system (such as another Novell router). It is not verified or exchanged with the remote system. The remote system ID is used by protocols such as IP and IPX to identify a connection to a partner system.
Press Enter to select a remote system ID, then enter a valid DTE address for the system in the Remote DTE Address field.
The Remote DTE Address parameter specifies the 15-digit X.121 DTE address assigned to the remote system. This address must correspond exactly to the calling DTE address, included in the Incoming Call packet received from the remote system. Otherwise, authentication fails and the incoming call is rejected.
In the X.25 Enterprise Specific Traps field, press Enter to view or modify the SNMP traps.
The X.25 Enterprise Traps Configuration menu is displayed.
In the Physical Bandwidth Threshold Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps while the Physical layer's send or receive utilization exceeds the Bandwidth Upper Threshold value. SNMP traps continue being generated until the Physical layer's send or receive utilization falls below the Bandwidth Lower Threshold value.
In the Bandwidth Lower Threshold field, set the value to any number greater than or equal to zero, but less than the Bandwidth Upper Threshold value.
Once the Physical layer's send or receive utilization exceeds the Bandwidth Upper Threshold value, the WAN driver continues to generate SNMP traps until the utilization falls below this value.
In the Bandwidth Upper Threshold field, set the value to any number greater than the Bandwidth Lower Threshold value.
Once the Physical layer's send or receive utilization exceeds this value, the WAN driver generates SNMP traps until the utilization falls below the Bandwidth Lower Threshold value.
In the Link State Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps when the Data-Link layer initialization is completed or a link failure is detected.
In the Packet Layer Restart Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps when the Packet layer receives or transmits a Restart Indication or Restart Request packet.
In the Packet Layer Reset Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps when the Packet layer receives or transmits a Reset Indication or Reset Request packet.
In the Call Setup Failure Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps when an X.25 call setup fails.
In the Virtual Circuit Cleared Trap field, accept the default value, Disabled, or press Enter to select Enabled from the pop-up list.
Enabling this parameter causes the WAN driver to generate SNMP traps when an X.25 call is terminated.
Press Esc and save your changes.
