100 Matrix SETU ATA211 System Manual
PCAP Trace
PCAP or packet capture consists of intercepting and logging the traffic passing over a digital network or a part of a
network. PCAP intercepts each packet in the data streams that flow across the network, and can decode and
analyze its contents.
PCAP can be used, among others, to monitor the network, analyze network problems, debug client/server
communications, debug network protocol implementations.
SETU ATA211 supports PCAP Trace, which you can use to detect and diagnose network related problems, for
example, when the SIP account is not getting registered, or any SIP related feature is not functioning.
Packets traveling over a network are captured and saved in the system. You can save these trace files (packets
captured by the system) on a PC and open these trace files using a graphical packet capture and protocol analysis
tool such as Wireshark or Ethereal.
A maximum of 1 MB of packets can be captured and stored in the system.
SETU ATA211 also supports Filters and Promiscuous mode for capturing packets, which you can use to specify the
types of data packets to be captured.
To use PCAP Trace from Admin mode,
1. Log in as Admin.
2. Click the Advanced Settings link on the left pane to expand.
3. Click PCAP.
4. Decide the type of packets to be captured and set the Filter accordingly. The Filter Settings parameter
should be maximum 60 characters in length. By default, this field is blank. So, all packets will be captured.
