ONT Product Information Guide
2 Enable or disable one or more of the following radio buttons, and click on the
Apply button to enable or disable tracing:
• OMCI—Tracing OMCI traffic allows you to review the transfer of data between
the P-OLT and the ONT, such as service provisioning data, anti-spoofing filters,
and leased IP addresses, and to test the physical layer of the GPON from the
P-OLT to the ONT. The OMCI trace can help to pinpoint faults in the fiber link
during or after installation.
• ARP—Tracing ARP protocol traffic allows you to review ARP dialog between the
ONT and host devices including ARP requests and responses for MAC addresses,
and to test the media access level of the network. Traces are displayed in
hexadecimal format (see Figure 6-29).
You can use a product, such as Wireshark, to decode traces.
• DHCP—Tracing DHCP protocol traffic allows you to review DHCP dialog
between the ONT and the CPE devices, and between the ONT and the P-OLT to
ensure CPE devices are able to request and obtain IP addresses for host
devices.
• IGMP—Tracing IGMP traffic allows you to monitor IGMP messages between host
devices and the ONT, and between the ONT and the LT to ensure proper IPTV
or IP video service to subscribers.
3 Enable one of the following radio buttons to specify the action for the system to
take when a log file is full, and click on the Apply button to apply setting:
• Stop logging—create only one log file.
• Append—create a second log file when the first log file is full. The content of
this second log file will be appended to the content of the first log file when
you view the log files, using Procedure 6-31.
4 STOP. This procedure is complete.
