CHAPTER 18

Diagnostic

18.1 Overview

The route between a CO VDSL switch and one of its CPE may go through switches owned by
independent organizations. A connectivity fault point generally takes time to discover and
impacts subscriber’s network access. In order to eliminate the management and maintenance
efforts, IEEE 802.1ag is a Connectivity Fault Management (CFM) specification which allows
network administrators to identify and manage connection faults. Through discovery and
verification of the path, CFM can detect, analyze and isolate connectivity faults in bridged
LANs.

18.1.1 What You Can Do in this Chapter

The 802.1ag screen lets perform CFM actions (Section 18.3 on page 156).

18.2 What You Need to Know

The following terms and concepts may help as you read through this chapter.

How CFM Works

A Maintenance Association (MA) defines a VLAN and associated Maintenance End Point
(MEP) ports on the device under a Maintenance Domain (MD) level. An MEP port has the
ability to send Connectivity Check Messages (CCMs) and get other MEP ports information
from neighbor devices’ CCMs within an MA.

CFM provides two tests to discover connectivity faults.

• Loopback test - checks if the MEP port receives its Loop Back Response (LBR) from its
target after it sends the Loop Back Message (LBM). If no response is received, there might
be a connectivity fault between them.

• Link trace test - provides additional connectivity fault analysis to get more information on
where the fault is. If an MEP port does not respond to the source MEP, this may indicate a
fault. Administrators can take further action to check and resume services from the fault
according to the line connectivity status report.

Troubleshooting

This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories.

• Power, Hardware Connections, and LEDs

• ZyXEL Device Access and Login

• Internet Access

19.1 Power, Hardware Connections, and LEDs

V The ZyXEL Device does not turn on. None of the LEDs turn on.

1 Make sure the ZyXEL Device is turned on.
2 Make sure you are using the power adaptor or cord included with the ZyXEL Device.
3 Make sure the power adaptor or cord is connected to the ZyXEL Device and plugged in

to an appropriate power source. Make sure the power source is turned on.

4 Turn the ZyXEL Device off and on.
5 If the problem continues, contact the vendor.

V One of the LEDs does not behave as expected.

1 Make sure you understand the normal behavior of the LED. See Section 1.5 on page 26.
2 Check the hardware connections. See the Quick Start Guide.
3 Inspect your cables for damage. Contact the vendor to replace any damaged cables.
4 Turn the ZyXEL Device off and on.
5 If the problem continues, contact the vendor.

19.2 ZyXEL Device Access and Login

V I forgot the IP address for the ZyXEL Device.

1 The default IP address is 192.168.1.1.
2 If you changed the IP address and have forgotten it, you might get the IP address of the

ZyXEL Device by looking up the IP address of the default gateway for your computer.
To do this in most Windows computers, click Star t > Run, enter cmd, and then enter
ipconfig. The IP address of the Default Gateway might be the IP address of the ZyXEL
Device (it depends on the network), so enter this IP address in your Internet browser.

3 If this does not work, you have to reset the device to its factory defaults. See Section 1.6

on page 28.

V I forgot the password.

1 The default password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See Section 1.6

on page 28.

V I cannot see or access the Login screen in the web configurator.

1 Make sure you are using the correct IP address.

• The default IP address is 192.168.1.1.

• If you changed the IP address (Section on page 72), use the new IP address.

• If you changed the IP address and have forgotten it, see the troubleshooting
suggestions for I forgot the IP address for the ZyXEL Device.

2 Check the hardware connections, and make sure the LEDs are behaving as expected. See

the Quick Start Guide.

3 Make sure your Internet browser does not block pop-up windows and has JavaScripts

and Java enabled. See Appendix B on page 197.

4 Reset the device to its factory defaults, and try to access the ZyXEL Device with the

default IP address. See Section 1.6 on page 28.

5 If the problem continues, contact the network administrator or vendor, or try one of the

advanced suggestions.

V I can see the Login screen, but I cannot log in to the ZyXEL Device.

1 Make sure you have entered the user name and password correctly . The default password

is 1234. These fields are case-sensitive, so make sure [Caps Lock] is not on.

2 Turn the ZyXEL Device off and on.
3 If this does not work, you have to reset the device to its factory defaults. See Section

19.1 on page 159.

19.3 Internet Access

V I cannot access the Internet.

1 Check the hardware connections, and make sure the LEDs are behaving as expected. See

the Quick Start Guide and Section 1.5 on page 26.

2 Make sure you entered your ISP account information correctly in the WAN screens.

These fields are case-sensitive, so make sure [Caps Lock] is not on.

3 If you are trying to access the Internet wirelessly, make sure the wireless settings in the

wireless client are the same as the settings in the AP.

4 Disconnect all the cables from your device, and follow the directions in the Quick Start

Guide again.

5 If the problem continues, contact your ISP.

V I cannot access the Internet anymore. I had access to the Internet (with the

ZyXEL Device), but my Internet connection is not available anymore.

1 Check the hardware connections, and make sure the LEDs are behaving as expected. See

the Quick Start Guide and Section 1.5 on page 26.

2 Turn the ZyXEL Device off and on.
3 If the problem continues, contact your ISP.

V The Internet connection is slow or intermittent.

1 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.5

on page 26. If the ZyXEL Device is sending or receiving a lot of information, try closing

some programs that use the Internet, especially peer-to-peer applications.

2 Check the signal strength. If the signal strength is low, try moving your computer closer

to the ZyXEL Device if possible, and look around to see if there are any devices that
might be interfering with the wireless network (for example, microwaves, other wireless
networks, and so on).

3 Turn the ZyXEL Device off and on.
4 If the problem continues, contact the network administrator or vendor, or try one of the
