Step 3 Use the NCP to enable event logging:
$ MCR NCP
NCP> SET logging MONITOR KNOWN Events
NCP> DEFINE logging MONITOR KNOWN Events
NCP> SET logging MONITOR STATE ON
NCP> DEFINE logging MONITOR STATE ON
Step 4 Exit NCP:
NCP> Exit
Step 5 To monitor network events from a console terminal, enter the following command at the
VMS system prompt:
$ REPLY/ENABLE = NETWORK
(This command is equivalent to the terminal monitor privileged exec command.)
DECnet: Connections to DEC Hosts Fail over Router (Router Problem)
Symptom: DECnet nodes cannot communicate when attempting to make connections over routers.
Note This section focuses on problems in the router. For end node–related problems and solutions,
see the section “DECnet: Connections to DEC Hosts Fail over Router (End Node Problem)” earlier
in this chapter.
Table 11-2 outlines the problems that might cause this symptom and describes solutions to those
problems.
Table 11-2 DECnet: Connections to DEC Hosts Fail over Router (Router Problem)
Possible Problem Solution
DECnet is not enabled
on
router
Step 1 Use the show decnet interface privileged exec command to see on which
interfaces, if any, DECnet is enabled.
Step 2 If the output shows that DECnet is not enabled, use the show running-config
privileged exec command to view the router configuration. Determine whether
DECnet global and interface command specifications are configured on the
router.
Step 3 Enable DECnet routing on the appropriate routers and interfaces. For detailed
information on configuring DECnet, refer to the Cisco IOS Network Protocols
Configuration Guide, Part 2.
Missing decnet cost
command
Step 1 Make sure that there is a cost configured on DECnet interfaces. Check the
configuration for a decnet cost cost-value interface configuration command
entry.
Step 2 If the command is not present, add the decnet cost command for each interface
on which DECnet is enabled.
End nodes and router
area number mismatch
Step 1 Check the configuration of end nodes and routers on the network segment. Check
the area address specified on end nodes and routers.
Step 2 If an end node is not in the same area as a router on the segment, you must either
change the address of the end node to be the same as a router on the segment, or
you must reconfigure a router on the segment with the same area number as the
end node.
