Troubleshooting DECnet 11-255
Using DECnet in a Multiprotocol Environment
Using DECnet in a Multiprotocol Environment
It is important to remember that DECnet changes the MAC addresses of router interfaces. This
behavior can cause problems for other protocols that are already enabled on the router.
If after enabling DECnet on a router interface other protocols (such as Novell IPX or XNS)
experience connectivity loss due to address resolution problems, the problem is probably a result of
DECnet changing the MAC address of the router interface.
As a rule, enable DECnet on router interfaces first, and then enable other protocols. Otherwise, use
the copy running-config startup-config command to save the router configuration and then reload
the router.
DECnet: Connections to DEC Hosts Fail over Router (End Node Problem)
Symptom: DECnet nodes cannot communicate when attempting to make connections over routers.
Note This section focuses on problems in end nodes. For router-related problems and solutions, see
the section “DECnet: Connections to DEC Hosts Fail over Router (Router Problem)” later in this
chapter.
Table 11-1 outlines the problems that might cause this symptom and describes solutions to those
problems.
