Novell IPX: Client Cannot Connect to Server on Remote LAN (continued)
Possible Problem
Solution
Ring speed
specification
mismatch has
occurred.
In a Token Ring environment, all devices must agree on the
configured ring speed (4 or 16 Mbps), or connectivity will fail.
Use the
show interfaces token
exec command on the router.
Look for the ring speed value in the output. Compare this
value with the ring speed specification on Novell servers.
1.
If the ring speeds do not match, change the server or router
configuration, as appropriate, so that all stations agree on the
ring speed. On routers, use the
ring-speed
interface
configuration command to change the
ring speed
. For
information about configuring the ring speed on Novell
servers, consult the vendor documentation.
2.
Duplicate node
numbers on
routers are
present.
1.
Use the
show running-config
privileged exec command to
examine the current configuration of each router in the path.
2.
Check the node number specified in the
ipx routing
node
global configuration command. The node number is either a
user-specified node number or the MAC address of the first
Ethernet, Token Ring, or FDDI
2
interface card in the router.
3.
The node number configured on each router must be unique.
If the number is the same on multiple routers, enter the
no
ipx routing
global configuration command to disable IPX
routing on the router.
4.
Reinitialize
IPX routing
by entering the
ipx routing
command (do not specify a node number). Use the
show
running-config
command to verify that the rest of the IPX
configuration is still correct.
Duplicate network
numbers are
present.
Every network number must be unique throughout the entire
Novell IPX internetwork. A duplicate network number will
prevent packets from being forwarded properly.
1.
Use the
show ipx servers
and the
show ipx route
privileged
exec commands. Check the output of these commands for
server addresses that have been learned from the wrong
interface.
For example, if you know that you have a server on the local
network with network number 3c.0000.0c01.2345, and the
show
command output shows that this server is located on a remote
network, there is probably a server on the remote network that's
using the same network number.
If you suspect a duplicate network number, use a process of
elimination to identify the misconfigured server. This can be
difficult, particularly if you do not have access to every
network device in the Novell IPX internetwork. When you
have identified the misconfigured server, modify the server
configuration to eliminate the duplicate network number.
