117379-A Rev. A B-3

2. 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.

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

workstation or DOS PC.

See Using Optivity Network Management System 8.0 Internetwork

Applications for Network Tap instructions.

b. 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 DOS PC, use the Packet Convert utility. See

“Con

verting a Packet Capture File to Network General Sniffer

Format” on page B-36.

c. Save the converted ﬁle on a 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.

3. 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.
