Information). However, unless you are using ARCnet* or some other media
that does not have IEEE addresses, only one system has the highest priority on
the LAN (the MAC address is used as a tie breaker and IEEE addresses are
unique). If necessary, change the priority on one of the contending routers.
Connectivity Across a Point-to-Point Link Has Been Lost
You cannot bring up an IPX point-to-point link, but IP is working.
Cause 1
—System on the other end of the link does not support IPXWAN, or
IPXWAN is not supported over the media that you use.
Contact the router manufacturer to verify that its product supports IPXWAN.
Cause 2
—Link has excessive errors.
Cause 3
—One of the IPXWAN implementations has an error.
Load MONITOR and view LAN/WAN Information under a specific NIC or
LAN adapter. Determine whether the link has excessive errors by viewing
discrepancies in packet error counts.
Issue the SET ISLL DEBUG=ON command and capture the IPXWAN
exchanges. Contact the manufacturer of the router that appears to be in
violation of the IPXWAN specification.
Cause 4
—Link has excessive errors.
Load MONITOR and view LAN/WAN Information under a specific NIC or
LAN adapter. Determine whether the link has excessive errors by viewing
discrepancies in packet error counts.
Cause 5
—Timers are misconfigured, causing the link to drop packets.
(Typically, the defaults are used for PPP.)
Check in MONITOR under Driver Statistics to determine whether this is the
cause. Set the timers so that the values match those set on the remote node.
Cause 6
—System is limited by the amount of memory or by the capacity of
the CPU or bus.
Load MONITOR and view memory utilization to determine if the capacity of
the CPU or memory is limiting the function.
Cause 7
—Link itself is corrupting data.
