P-2024 Support Notes

Using Embedded Packet Trace

Embedded Packet Trace

The P-2024 packet trace feature records and analyzes packets running on the LAN and WAN interfaces. It is

designed for technical users who are interested in the details of the packet flow on the P-2024＇s LAN or WAN

interface. It is also a diagnostic tool 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 packet trace result display is as follows:

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 view the trace result:

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

2. Offline Trace--capture the trace first and display later

The following details the trace commands in SMT menu 24.8.
