To capture packets using the Ethernet software:
Connect the IP phone’s Internet port with the PC to the same HUB, and then use Sniffer,
Ethereal or Wireshark software to capture the packets. You can also set a mirror port in
the switch to monitor the port of the connected IP phone.
The IP phone provides a troubleshooting feature called ―Watch Dog‖, which helps you
monitor the IP phone status and provides the ability to get stack traces from the last time
the IP phone failed. When the Watch Dog feature is enabled, the IP phone will
automatically reboot when it detects a fatal failure. This feature can be configured using
the configuration files or the web user interface.
You can use the ―watch_dog.enable‖ parameter to configure the Watch Dog feature in
the configuration files. For more information, refer to Watch Dog on page 317.
To configure the Watch Dog feature via web user interface:
1. Click on Phone->Preference.
