Pcap Trace - Matrix Telecom SARVAM UMG 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.
SARVAM UMG 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 a 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 computer and open these trace files using a graphical packet capture and protocol
analysis tool such as Wireshark or Ethereal.
A maximum of 10 MB of packets can be captured and stored in the system.
SARVAM UMG 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,
• Click the Maintenance link to expand.
• Click the PCAP link.
• Decide the type of packets to be captured and set the Filters accordingly. The Filter Settings must be
within 60 characters. By default, this field is blank. So, all packets will be captured.
