3. Check for file server on Remote Office switch
Does the file server appear in the IPX service table of the Remote Office
switch? If the server does not appear in the table, its presence is not
advertised to the local LAN. To check this, enter the command:
SHOW IPX SERVICE
This should produce a display like that shown in Figure 29 on page 117. The
important point is that the file server must appear in the service table on the
Remote Office switch and there must be a route to the file server's internal
network number. If there is, and it still does not work, contact your
authorised distributor or reseller for assistance.

To interpret output from the SHOW IPX SEVICES command see the Novell
IPX chapter in the AT-8800 Series Switch Software Reference.
4. Check route tables
To check the route tables on both switches, enter the command:
SHOW IPX ROUTE
Check for the presence of networks on the remote side of the wide area
network. If the remote network is missing from the route table on either
switch, enter the command:
RESET IPX
which resets the IPX routing software and forces the switches to broadcast
their routing and service tables.

Using Trace Route for IP Traffic

You can use trace route to discover the route that packets pass between two
systems running the IP protocol. Trace route sends an initial UDP packets with
the Time To Live (TTL) field in the IP header set starting at 1. The TTL field is
increased by one for every subsequent packet sent until the destination is
reached. Each hop along the path between two systems responds with a TTL
exceeded packet and from this the path is determined.
To initiate a trace route, enter the command:
TRACE [[IPADDRESS=]ipadd] [MAXTTL=number] [MINTTL=number]
[NUMBER=number] [PORT=port-number] [SCREENOUTPUT={YES|NO}]
[SOURCE=ipadd] [TIMEOUT=number] [TOS=number]
