Packet Capture
The Cisco Business Edition 3000 Administrative Interface supports capturing the network packets on a server.
While troubleshooting, it is sometimes necessary to collect network packets that are being sent to and from
the network interface on a Cisco Business Edition 3000 server.
The following table describes the settings on the Packet Capture tab.
Packet Capture is resource-intensive and the system might be less responsive while it is enabled. Note
Table 42: Settings on the Packet Capture tab
Description Setting
Packet Capture allows you to capture the network packets in
two ways:
• Capture packets to and from IP address—Choose this
option to capture the network packets to and from a
particular IP address.
• Capture all packets—Choose this option to capture all
the network packets.
Capture Packets
To start packet capture, click Start Packet Capture . The time
stamp displays the current date and packet capture start time.
If the packet capture file exists on a system, the following
warning message appears:
You can keep only one packet capture file on the
server at a time. If you generate a new one, the
existing file will be replaced with the new one.
Warning
While the packet capture is running, you can also attempt to
reproduce the problem.
Start Packet Capture
To stop the packet capturing, click Stop Packet Capture . The
time stamp displays the current date and packet Capture stop
time.
Packet capture stops when it captures 100,000 network packets.
The captured packets are saved in Packetcapture< Timestamp
in YYYY-MM-DD_hh-mm-ss>.cap file format. The time
stamp displays the time when the packet capturing was started.
Stop Packet Capture
A link allows you to download the captured network packets
to your PC.

packets.
