Access the Management and Diagnostic Console 49 Firewall - Advanced Settings Page The Firewall - Advanced Settings page allows you to configure the gateway’s firewall. For details on configuring advanced firewall settings, refer to page 29.
Access the Management and Diagnostic Console 50 Troubleshooting - DSL Diagnostics Page The Troubleshooting - DSL Diagnostics page displays data associated with the 3700HGV-B gateway’s VDSL link. Note: Most of the values displayed on this pag e are calculated once at the star t of the connection. Values that are dynamically updated during the connection are marked with an asterisk (*). Analyzing General Information The General Information pane shows diagnostic informat ion for the current VDSL connection (or connection attempt). These values are also listed in the last row of the Training Histor y pane. Item Description Value Comment DSL Line During line search, the value will alternate between 1 and 2. The “Searching for DSL signal” comment appears until the VDSL protocol is con- firmed with the DSLAM on the current line. 1 or 2. None or Search- ing for DSL sig- nal . Downstream Atten. at 300kHz
Access the Management and Diagnostic Console 51 Reviewing Training Histor y This pane provides a record of the last 20 connection attempts. The current connection or connection attempt is displayed in the last row.Final Rx Gain Indicates the current receive gain setting (in dB). Dependent on DSL line length. Ok or Suspicious - possible satura- tion . Delay of latency path The delay, in millisec- onds, imposed by the modem on the interleaved frames. Item Description *Time Initially this field will display the time (since power on) in DAYS HH:MM:SS format, until the gateway can access the Internet and retrieve the current local time. Subsequently the time (since power on) is displayed in YY:MM:DD and HH:MM:SS format. Line The line (1 or 2) on which the gateway is searching for a DSL signal. Downstream Rate The net user data rate (in kbps) for the connection. Max1 Maximum rate achievable at the time of the initial connec- tion based on the line quality (specifically, the uncapped rate). *Max2 Latest estimate of maximum achievable rate adjusted for changing line conditions. Mgn1 Noise margin (in dB) at the start of the connection. *Mgn2 Latest noise margin adjusted for changing line conditions since the connection was first established. Attn Measured attenuation (dB) of the line. Pwr Transmit power (dB). *CRCs Total uncorrected errors for this connection. *FECs Total corrected errors for this connection. Upstream Rate The net user data rate (in kbps) for the connection. Item Description Value Comment
Access the Management and Diagnostic Console 52 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 value (0 to F) in addition to the bar-graph depiction.* Max Maximum rate achievable at the time of the initial connec- tion based on the quality of the line (specifically, the uncapped rate). Mgn Noise margin (in dB) at the start of the connection. Attn Measured attenuation (dB) of the line. Pwr Transmit power (dB). *CRCs Total uncorrected errors for this connection. *FECs Total corrected errors for this connection. Mode The DSL mode used. Vendor Vendor ID of the DSLAM (for example, ALCB indicates Alca- tel DSLAM in G.DMT mode). Rx Gain Indicates the current receive gain setting, which will depend on the length of the DSL line. Item Description
Access the Management and Diagnostic Console 53 Troubleshooting - Event Log Page The Troubleshooting – Event Log page displays events for the broadband and local network. Log information is stored in a fixed-size 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.
Access the Management and Diagnostic Console 54 Users can view specific information by selecting which log to view from the pull-down menu and then clicking the Filter button. 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 regi sters all significant Firewall Monitor-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 descriptio n 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 or Warning severity level. Informational indicates events that are informational only; Warning indicates an unexpected c ondition that does not affect the 2Wire gateway’s ability to operate (for example, a network problem or the 2Wire gateway is not configured properly).
Access the Management and Diagnostic Console 55 Troubleshooting - Network Tests Page The Troubleshooting – Network Tests page provides the Traceroute and Ping tools, which help diagnose problems with the 2Wire gateway or 2Wire gateway connections. The Ping test allows you to ensure that the 2Wire gateway can send data packets to (ping) a remote host or a local LAN device (such as a PC). The Traceroute test traces the number of times a data packet sent from the 2Wire gateway is routed befor e it reaches its destination.
Access the Management and Diagnostic Console 56 Troubleshooting - Upgrade Histor y Page The Upgrade Histor y page shows a log of all system software upgrades, and lists the upgrades in the order in which they occurred.
Access the Management and Diagnostic Console 57 Troubleshooting Resets Page The Troubleshooting – Resets page allows you to reset various components associated with the 2Wire gateway network.
Access the Management and Diagnostic Console 58 Advanced - Syslog Settings Page The Advanced - Syslog Settings page allows users to maintain a history of events greater than the capacity of the 2Wire gateway by enabling a syslog ser ver. Use of this feature requires a computer running a syslog daemon.
