Possible Problem Solution
Misconfigured end node
Step 1 Check the end node configuration using the show executor
characteristics NCP
1
command.
Step 2 Make sure that the end node type (nonrouting Phase IV, routing Phase IV,
area), node address, node name, and routing and link parameters are
correctly specified.
Step 3 Check the circuit characteristics using the show known circuit
characteristics NCP command.
Step 4 Make sure that the designated router, hello timer, router priority (if the
node is a routing node), and other circuit characteristics are properly
configured.
The following decnet commands are used to set the designated router,
hello timers, and router priority on a Cisco router:
decnet hello-timer seconds
• seconds—Interval at which the Cisco IOS software sends hello
messages. It can be a decimal number in the range 1 to 8191 seconds.
The default is 15 seconds.
decnet router-priority value
To elect a designated router to which packets will be sent when no
destination is specified, use the decnet router-priority interface
configuration command.
• value—Priority of the router. This can be a number in the range 0
through 127. The larger the number, the higher the priority. The
default priority is 64.
Step 5 Reconfigure the end node if any of the end node or circuit characteristics
are misconfigured. For information on configuring end nodes, refer to the
vendor documentation.
Host access control rejects
connection
With this problem, users see the message “connect failed, access control rejected.”
This is typically a session-layer problem.
Step 1 Make sure that the following requirements are satisfied:
• User-supplied access control information is correct
• Proxy access is set up correctly
• Proxy database and proxy account are correct
Step 2 Make sure that the user’s security access matches the access
specifications for the user on the remote systems.
Step 3 If there are problems in any of these areas, make changes as necessary.
