1252 Matrix ETERNITY NE 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, detect and analyze network problems, debug client/
server communications, debug network protocol implementations.
SARVAMUCS supports PCAP Trace for the Ethernet Port and the Matrix Extended IP Phones. PCAP Trace is
supported for both IPv4 and IPv6 addresses.
The PCAP Trace of the Extended IP Phones can be accessed using the FTP of the phone. The access to the FTP
is secured by a password and it can be changed. For detailed instructions, see “FTP Access for Extended IP
Phones”.
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.
SARVAM UCS also supports Filters and 'Promiscuous' mode for capturing packets, which you can use to specify
the types of data packets to be captured.
