Troubleshooting a Quick Configuration
If the router fails to operate in your network after you have used the
Quick Configuration utility, there are several areas to investigate for the
source of the problem:
Check the Quick Configuration display for errors or omissions in the
data that you provided.
Ensure that your network design allows for any Quick Configuration
default settings that may remain after you entered your parameter
values.
Ensure that you save the configuration and then reboot (page 3-9).
Ensure that all cable connections are firm and are routed properly.
Check the LEDs on all connected routers to ensure that all ports are
operating properly.
Use the NCL Ping command to send an ICMP echo request message
to each IP address connected to your router. (Refer to the ‘‘NCL
Command Summary’’ on page 7-7 or to the Operator’s Reference.)
Determine whether there is any need for additional configuring, as
indicated by unique or advanced configuration features used in the
network(s) to which your router is connected. (Refer to ‘‘When To
Use the Configuration Editor’’ on page 3-29.)
Check the event log to ensure that configured services (such as IP)
have started and are running properly. (Refer to the operator’s guide
for your router.)
Check the statistics screens you can access from the Main menu for
signs of impeded or failing operation.
Check your current configuration against the configurations of
adjacent routers to detect any settings that require reciprocal values
(such as DTE and DCE for WAN ports). Also check for any simple
configuration errors such as duplicate or incorrect IP addresses, or
incorrect subnet masks. (Create a list of interdependent values in the
other router(s) that dictate related or reciprocal settings in your
router.)
The installation and operator’s guides for your router provide additional
help for investigating and analyzing router operation and failures.
