Reviewing Bitloading
The Bitloading pane shows the bits loaded per tone for the upstream (tones 6 to 31) and downstream 
(tones 32 to 255) spectrum. A single hex-digit for each tone shows the numeric values (0 to F) in addition to 
the bar-graph depiction.Exit Code Indicates the reason for a lost connection or a terminated training attempt. 
Following are examples of the typical values that can be represented:
ERR_LOF_LIMIT - Retrained due to loss of framing.
ERR_LOS_LIMIT - Retrained due to loss of signal.
ERR_HI_BER_LIMIT - Retrained due to excessive CRCs.
RESTART - System deliberately restarted modem (line search, reprovisioning, or 30-
second timeout when waiting for DSL signal.
ERR_STATE_TIMEOUT - Modem timed out during training (for example, the modem 
failed to detect pilot signal at the appropriate time).
ERR_ALL_OPTIONS_FAIL - Failed to negotiate a final bitrate with DSLAM.
RETRAIN_HIGHER - Proactive retrain in order to obtain a significantly higher connect 
rate.
Echo A measure of the uncancelled echo relative to the background noise on the line. 
This is an indication of how much the uncancelled echo is affecting DSL 
performance, rather than an absolute measure of the uncancelled echo.
VXCO Indicates the difference between the gateway’s and the DSLAM por t’s cr ystal 
frequency in par ts per million (ppm).
Rx Gain Indicates the current receive gain settings, which will depend on the length of the 
DSL line.
INC Tones Indicates the number of compensation tones on which impulse noise is detected. Item Description

Troubleshooting - Event Log Page
The Troubleshooting – Event Log page displays all security related events for the broadband and local 
network. Log information is stored in an 8 KB buffer. When the buffer is full, the oldest items are purged 
from the log. You can also clear the log contents by clicking the 
Clear Log button. 
Figure 41. MDC Troubleshooting Event Log Page
You can view specific information by selecting which log to view from the pull-down menu and then clicking 
the 
Filter button (the screen capture depicted above has the system filter applied). Following are 
descriptions of the logs.
Access. Shows the current access log, which registers all significant Content Screening and Internet 
Access Control events.
All. Shows all logs that register a significant event (access, firewall, fw aler t, system, and wra).
Firewall. Shows all detailed firewall events, including Internet Access Control and Firewall Monitor.
FW Alert. Shows the current Firewall Monitor log, which registers all significant Firewall Monitor-related 
events. 
						

							Management and Diagnostic Console

HURL. Shows the Broadband Redirect messages that have been enabled by a ser vice provider.
Modem. Shows the current modem log, which registers all significant modem-related events.
System. Shows the current system log, which registers all significant events within the 2Wire gateway 
since it was last restarted.
WRA. Shows the current Web Remote Access log, which registers all significant Web Remote Access-
related events.
Each log entr y includes the severity level, a description of the event, and the actual time that it occurred. 
The most recent events display at the bottom of the list.
Events generate an Informational (INF) or Warning (WRN) severity level. Informational indicates events that 
are informational only; Warning indicates an unexpected condition that does not affect the 2Wire gateway’s 
ability to operate (for example, a network problem or the 2Wire gateway is not configured properly).
For events that involve the transfer of packets, the following additional information is displayed.
Item Description
src Source IP address
dst Destination IP address
ipprot Protocol number as indicated in the IP header field
spor t Source por t (TCP and UDP)
dport Destination port (TCP and UDP)
Disposition of the event The action taken when the event occurs (for example, 
“Unknown inbound session stopped”)

Troubleshooting - Network Tests Page
The Troubleshooting – Network Tests page provides the Ping, Traceroute, and DNS Query tools, which help 
diagnose problems with the 2Wire gateway or 2Wire gateway connections.
Figure 42. MDC Troubleshooting Network Tests Page
The Ping test allows you to ensure that the 2Wire gateway can send data packets to (ping) a remote host. 
The Traceroute test traces the number of times a data packet sent from the 2Wire gateway is routed before 
it reaches its destination. The DNS Query test finds the IP address of the domain name ser vice. 
						

							Management and Diagnostic Console
100
To perform a ping or traceroute test:
1.From the drop-down menu, select Ping or Traceroute.
2.In the Host field, enter the URL of the host location to which you wish the 2Wire gateway to send the 
ping or traceroute.
3.In the Test field, enter the number of times you want the ping to occur (the maximum is 25) or the 
number of hops you want traceroute to trace.
4.In the Packet Size field, enter the packet size you wish to send. The maximum packet size is 576.
5.Check the Enable network name resolution checkbox. This will ensure that the name of the host location 
is displayed along with the corresponding IP address.
6.Click the Star t button.
The results are displayed on the page as they occur, and include round trip latency; the aggregate number of 
packets sent, received, and lost; and the minimum, maximum, and average round-trip latency.
To discontinue Ping or Traceroute, click the 
Stop button.
To perform a DNS query:
1.From the drop-down menu, select DNS Query.
2.In the Host field, enter the domain name (URL) for which you wish to obtain the IP address.
3.Click the Star t button.

Troubleshooting - Upgrade History Page
The Troubleshooting - Upgrade Histor y page shows a log of all system software upgrades, and lists the 
upgrades in the order in which they occurred.
Figure 43. MDC Troubleshooting Upgrade History Page 
						

							Management and Diagnostic Console

The Upgrade History page shows the following information.
Item Description
Model number The 2Wire gateway model number.
Hardware version The current 2Wire gateway hardware version.
Software version The current 2Wire gateway software version.
Upgrade Log The initial software version, and a record of the last 10 
upgrades.

Troubleshooting - Resets Page
The Troubleshooting – Resets page allows you to reset various components associated with the 2Wire 
gateway network.
Figure 44. MDC Troubleshooting Resets Page
The Clear button in the Local Network field clears all devices from the Local Network list. Doing so will 
change the configuration settings, and may affect 2Wire gateway operation because it removes all devices 
(such as computers) from your network.
The 
Reset button in the DSL Connection field retrains the 2Wre gateway’s DSL connection.
The 
Reset button in the ISP Connection field resets the PPP connection and/or releases and renews the 
broadband IP address.
Note: To access this page, your network must have the Remote Management feature enabled. 
If the feature is not enabled, an error message will display when you click the link to access 
this page. 
						

							Management and Diagnostic Console
104
The Reset button in the Broadband Link field allows you to reset the 2Wire gateway broadband link. For 
2Wire gateway models with a DSL connection, this means the DSL connection is reset.
The 
Reset button in the Gateway field allows you to restart the 2Wire gateway. During 2Wire gateway restar t, 
the Troubleshooting page cannot be accessed until the 2Wire gateway completely restarts and the 
connection is reestablished.
The 
Reset button in the to Factory State field resets the 2Wire gateway to an unprovisioned default state. 
Doing so will remove all your configuration settings, and requires 2Wire gateway software reinstallation.
Wa r n in g :  Resetting the 2Wire gateway to an unprovisioned default state will clear all update 
records from the Upgrade History page, and delete all provisioning, firewall, and Enhanced 
Ser vices configuration settings.

Advanced - Syslog Settings Page
The Advanced - Syslog Settings page allows users to maintain a history of security events greater than the 
capacity of the 2Wire gateway by enabling a syslog ser ver.
Figure 45. MDC Advanced Syslog Settings Page
To enable syslog and specify the location of a syslog server:
1.Check the Enable Syslog checkbox.
2.In the Server Location field, enter the IP address of a UNIX or Linux computer running a syslog daemon.
3.Optional: In the Ser ver Por t field, enter the outbound port number upon which the syslog ser ver is 
located.
4.To limit the number of log packets, check the Enable Throttling checkbox.
5.In the Limit Logging to field, enter the number of logs per second that you wish to log.
6.Click the Submit button.
Note: Use of this feature requires a UNIX or Linux computer running a syslog daemon.
