System Tools; Back Up And Restore Configuration; Figure 11-8. Trace Display For A Failed Tcp/Ip Protocol Connection - NETGEAR RT338 Reference Manual

Figure 11-8 shows an example of a trace display for a failed call when using a TCP/IP Protocol
connection. In this case, the login name or password may be incorrect, because the first sign of a
problem is the LCP down message immediately following the PAP login step.

Another useful diagnostic tool for TCP/IP testing is Ping Host, which causes a packet to be sent to
a specified host requesting an echo packet. Enter 12 to select Ping Host. This diagnostic test pings
a local or remote host. You are prompted for the IP address of the host.

System Tools

Enter 21 to select Reboot System. The system is reboots, implementing any changes that may have
been recently added to your system.
Enter 22 to select Command Interpreter Mode. This option changes the Manager interface on your
router from the screen-based mode to a command line mode. The command line mode lets you
configure, diagnose, and test your router using a specified set of commands. For more information,
refer to "Using Command Interpreter Mode" on page

Back Up and Restore Configuration

The router configuration settings can be saved to a disk as a binary file. You can also restore the
settings from the file at a later time. Saving and restoring the router configuration lets you restore
the router to working order if the configuration information in the router is lost or damaged. You
can also use the configuration file to configure a new router of the same type if it becomes
necessary to replace the router.
