In-Depth Information
In some of the symptom discussions that follow, Operator Communication Manager
(OPCOM) messages are used to illustrate certain errors. These examples assume that
OPCOM is running and event logging is enabled. For more information about event
logging, see the section “Configuring a DECnet Node to Log DECnet Events” later in this
chapter.
Note
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.
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.
