Establish a remote connection to the router using FTP, TFTP, XMODEM, or

the Network Tap application; then, use a Network General Sniffer to convert

the file for processing.

Transfer a copy of the Packet Capture file from the router to a UNIX

workstation or MS-DOS PC.

See

Using Optivity Network Management System 8.0 Internetwork

Applications

for Network Tap instructions.

Convert the file for processing by a Network General Sniffer using one of

the following methods:

• On a UNIX workstation, use Network Tap.

• On a Sun workstation or MS-DOS PC, use the Packet Convert utility.

See “Converting a Packet Capture File to Network General Sniffer

Format” on page B-36.

Save the converted file on an MS-DOS-formatted diskette and insert the

diskette in a Network General Sniffer for analysis. See the Network

General Sniffer manual to learn how to read the file.

Establish a local or out-of-band connection to the router using the Technician

Interface; then, use the Technician Interface to decode and display the

hexadecimal content of the packets.

The Technician Interface shows the following information about each packet:

• The sequential number of the packet in the file

• The date and time Packet Capture copied the packet

• The media carrying the packet

• The original size of the packet

• The direction of the packet (received for incoming, or transmitted for

outgoing)

• The contents of the packet in hexadecimal format.

The Technician Interface also allows you to do the following:

• Identify the first packet you want to display by specifying its sequence

number in the Packet Capture file.

• Limit the number of packets displayed.
