TROUBLESHOOTING IPX CONFIGURATIONS

No Routes are Visible to the Remote Router

1

   Check the PPP link is active, using the command:

SHOW PPP

The display should look like that shown above. The state of the
IPX control protocol (IPXCP) should be “OPENED”. If not,
then the fault lies with the connection between the two
routers, or the PPP configuration at either end of the link.

2

   Check that the IPX circuits are correctly configured on each

router by repeating steps 1 through 3 above, or by typing:

SHOW IPX CIRCUIT

Check that there are two circuits, and for each circuit check
that the circuit is enabled, uses the correct interface and
encapsulation (for Ethernet interfaces), the network number is
correct and “On demand” is set to “no”. If not, then repeat
steps 1 through 3.

   Contact your distributor or reseller for assistance.

Local Workstations Can Not Access Remote Servers

This problem can be caused by a number of different events.

The following give some of the most common:

1

   Check that when the workstation is moved to the same

LAN as the file server, it is able to access the server. If not, the

fault lies with the configuration of the workstation or file

server. Check with your Novell network administrator.

2

   Care must be taken with the workstation NET.CFG file.

Always specify the encapsulation (frame) as different LAN card

drivers use different default encapsulations.

ROUTES command for a basic Novell

IPX network.

SERVICES command for a basic

Novell IPX network.
