5.9 Capturing Packets Through the Packet Capture Tool

You can connect the LAN interface of an IP phone and a computer to the same hub, and use
the packet capture software such as the Sniffer, Ethereal, or Wireshark to capture packets.
Alternatively, you can configure mirroring on the interface connected to the IP phone. You
can locate faults quickly by analyzing the captured packets. You are advised to use the
Wireshark-0.99.6a software to capture and analyze packets.
For details on how to capture and analyze packets, see the following document:

analyze packets. To modify settings, do as follows:

On the Capture dialog box, you can specify the network adapter where packets need to
be captured, and determine whether to capture packets in promiscuous mode. (capture all
the packets passing through the network adapter, whether to update packets in real time,
whether to scroll packets automatically, and whether to hide the packet capture dialog
box.)
