LAN/WAN Packet Trace

You can use the packet trace feature on the Prestige to record and analyze packets transmitting through the LAN and WAN interfaces. It is designed for technical users who are interested in the details of the packet flow on the Prestige＇s LAN or WAN interface. It is also a very helpful diagnostic tool to solve Internet connection problems or if you want to know the details of a packet for configuring a filter rule.

The format of the result is displayed as follows:

Packet:

011880.160 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 display the trace results:

1.Online Trace--display real-time trace results on the screen

2.Offline Trace-- save the trace results first and display them later

The following shows you how to obtain and display the packet trace results in SMT menu 24.8 are as follows.
