1. LAN/WAN Packet Trace

The Prestige 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 Prestige. 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:

• Online Trace--display the trace real time on screen

• Offline Trace--capture the trace first and display later

The details for capturing the trace in SMT menu 24.8 are as follows.

Online Trace
