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.
