Embedded Packet Trace
The P-334WT packet trace records and analyzes packets running on LAN and WAN interfaces. It is
designed for users with technical backgrounds who are interested in the details of the packet flow on
LAN or WAN end of P-334WT. It is also very helpful for diagnostics if you have compatibility problems
with your ISP or if you want to know the details of a packet for configuring a filter rule.
The format of the display is as following:
Packet:
0 11880.160 ENET0-R[0062] TCP 192.168.1.2:1108->192.31.7.130:80
[index] [timer/second][channel-receive/transmit][length] [protocol] [sourceIP/port] [destIP/port]
There are two ways to dump the trace:
1. Online Trace--display the trace real time on screen
2. Offline Trace--capture the trace first and display later
