Troubleshooting IPX Configurations

No Routes are Visible to the Remote Router

1.Check the PPP link

To check that the PPP link is active, enter the command:

SHOW PPP

The display should look like that shown in Figure 28 on page 116. The state of the IPX control protocol (IPXCP) should be “OPENED”. If not, then the fault lies with the connection between the two switches, or the PPP configuration at either end of the link.

Figure 28: Example output from the SHOW PPP command for a basic Novell IPX network.

NameEnabled ifIndex OverCPState

-----------------------------------------------------------------------------

ppp0	YES	04	IPXCP	OPENED
		isdn-roho	LCP	OPENED

-----------------------------------------------------------------------------

To interpret output from the SHOW PPP command see the Point-to Point

(PPP) chapter in the AT-8800 Series Switch Software Reference.

2.Check IPX circuit configuration

To check that the IPX circuits are correctly configured on each switch repeat steps 1 through 3 above, or enter the command:

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.

3.Contact your authorised distributor or reseller for assistance

If you still have no visible routes to the remote switch, contact your authorised distributor or reseller for assistance.

Local Workstations Can Not Access Remote Servers

A number of different events can cause this problem. The following list of events gives the most common:

1.Move workstation to server LAN

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.Check NET.CFG file

Take care with the workstation NET.CFG file. Always specify the encapsulation (frame) as different LAN card drivers use different default encapsulations.
