Restore Configuration
Restore Configuration allows you to upload a new or previously saved configuration file from your
computer to your Device.
Do not turn off the Device while configuration file upload is in progress.
After the Device configuration has been restored successfully, the login screen appears. Login again
to restart the Device.
The Device automatically restarts in this time causing a temporary network disconnect. In some
operating systems, you may see the following icon on your desktop.
Figure 143
Network Temporarily Disconnected
If you uploaded the default configuration file you may need to change the IP address of your
computer to be in the same subnet as that of the default device IP address (192.168.1.1). See
Appendix A on page 291
for details on how to set up your computer’s IP address.
If the upload was not successful, the following screen will appear. Click
OK
to go back to the
Configuration
screen.

The Reboot Screen
System restart allows you to reboot the Device remotely without turning the power off. You may
need to do this if the Device hangs, for example.
Click
Maintenance > Reboot
. Click
Reboot
to have the Device reboot. This does not affect the
Device's configuration.

Overview
The
Diagnostic
screens display information to help you identify problems with the Device.
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.

What You Can Do in this Chapter
The
Ping & TraceRoute & NsLookup
screen lets you ping an IP address or trace the route
packets take to a host (
Section 35.3 on page 279
).
The
802.1ag
screen lets you perform CFM actions (
Section 35.5 on page 281
).
The
OAM Ping Test
screen lets you send an ATM OAM (Operation, Administration and
Maintenance) packet to verify the connectivity of a specific PVC. (
Section 35.5 on page 281
).
35.2
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.
