The ZyXEL Device 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 the ZyXEL Device. 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
