Maintenance and Troubleshooting

This Chapter

If you are familiar with networking and router operations, you may be able to
diagnose and solve some problems yourself.
This chapter gives tips on how to:
■
start your router (see "How the Router Starts Up" on page 124).
■
avoid problems (see "How to Avoid Problems" on page 125).
■
reconfigure your router if you accidentally clear the FLASH memory (see
"What to Do if You Clear FLASH Memory Completely" on page 127).
■
troubleshoot a PPP link that disconnects (see "What to Do if the PPP Link
Disconnects Regularly" on page 128).
■
reset passwords if they are lost (see "What to Do if Passwords are Lost" on
page 128).
■
gather information from your router that support personnel need to
provide accurate support tailored to your situation (see "Getting the Most
Out of Technical Support" on page 128).
■
restart the router at any time with no configuration (see "Resetting Router
Defaults" on page 129).
■
check whether there is a connection between the router and another
routing interface in the network (see "Checking Connections Using PING" on
page 129).
■
troubleshoot if no routes exists to the remote router (see "Troubleshooting IP
Configurations" on page 130 and "Troubleshooting IPX Configurations" on
page 132).
■
troubleshoot problems with DHCP IP addresses if the router is acting as a
client or as a server (see "Troubleshooting DHCP IP Addresses" on page 132)
■
examine the route that packets pass between two systems running the IP
protocol (see "Using Trace Route for IP Traffic" on page 134).
Information gained from the LEDs on the front panel of the router is described
in the Hardware Reference.
