SBG6580 (v8.5.x): Diagnostics Tool

What tools can I use to test connectivity in my SBG6580?

The Diagnostics page in the SBG6580 includes various tools that are used for troubleshooting IP connectivity issues.  This document describes how to utilize the Ping and Traceroute functions.

Ping (Packet Internet Gopher) - A test used to check connectivity from the SBG6580 to another device on the Internet or the LAN (Local Area Network).  Using the ping feature, the SBG6580 sends a small packet of data to a device, and waits for a reply from that device.  If the device replies, this confirms that the SBG6580 and that device are able to communicate with each other.

Traceroute - A test used to map the network path from the SBG6580 to a remote device on the Internet.  This can be useful when a device fails the ping test.  If the device can be accessed, the traceroute test will display every hop taken to get to the destination.  If it cannot be accessed, the SBG6580 will display the last hop taken before the connection terminated.  This is useful to pinpoint where a connectivity issue is.

NOTE: Some devices are configured to block incoming ICMP (Internet Control Message Protocol) packets.  As a result, the ping and traceroute tests may fail, although the device itself is up and running.

How to access the Ping & Traceroute Utilities

1. Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter http://192.168.0.1 into the address box, and press the Enter key.  The Login page appears.
   
   NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.
    
2. On the Login page:
   a.   Enter admin in the Username field.
   b.   Enter motorola in the Password field.
   c.   Click the Login button.  The Home page appears.

1. Click the drop-down menu under Select Utility, and select Ping WAN.
    
2. For Ping Test Parameters:
   a.   Target - Enter the IP address of the computer to ping.
   b.   Ping Size - Enter the size of the data packet to be used for each ping attempt.
   c.   No. of Pings - Enter the number of ping attempts the SBG6580 will send to the computer.
   d.   Ping Interval - Enter the time for the SBG6580 to wait (in milliseconds) before sending each ping attempt.
   e.   Start Test - Click this button to start the ping test.
   f.    Abort Test - Click this button if it's desired to stop the ping test.
   g.   Clear Results - Will clear the information in the Results box below.
    
3. Results - Area where the SBG6580 will display the results of the test.
   
    
    

Using the Ping LAN utility

The Ping LAN utility is used to check connectivity from the SBG6580 to another device on the LAN (Local Area Network).

1. Click the drop-down menu under Select Utility, and select Ping LAN.
    
2. For Ping Test Parameters:
   a.   Target - Enter the IP address of the computer to ping.
   b.   Ping Size - Enter the size of the data packet to be used for each ping attempt.
   c.   No. of Pings - Enter the number of ping attempts the SBG6580 will send to the computer.
   d.   Ping Interval - Enter the time for the SBG6580 to wait (in milliseconds) before sending each ping attempt.
   e.   Start Test - Click this button to start the ping test.
   f.    Abort Test - Click this button if it's desired to stop the ping test.
   g.   Clear Results - Will clear the information in the Results box below.

Using the Traceroute utility

1. Click the drop-down menu under Select Utility, and select Traceroute.
    
2. For Traceroute Parameters:
   a.   Target - Enter the IP address or Host Name of the destination device  
   b.   Max Hops - Enter the maximum number that the Traceroute operation performs before stopping.
   c.   Data Size - Enter the size of the data packets to be sent to the destination device.
   d.   Base Port - By default, this is set to UDP port 33434. The default port is usually sufficient. If desired, change this setting to the number of choice.
   e.   Resolve Host - Click the drop-down menu, and choose the desired setting.
         
         NOTE: Select On if it is desired to list the host name of every gateway (hop) used during the Traceroute operation.  Select Off if it is desired to list the IP address of every hop.
    
3. Click the Start Test button to start the Traceroute test.  The results of the Traceroute rest will display in the Results section.
4. If desired, click the Clear Results button to clear the information in the results box below.
