.h1;Installation

                      ** NOTE **

When following the instructions in this release memo, be sure
to press the Return key after typing each command.

Copy SW/200-TCP-PKTGEN-NCS/150 Version 20100 from the
distribution to the SW/150-NCS-TCP diskette using the following
procedure:

1.  Attach a terminal to port 0 of the NCS/150.

2.  Insert the SW/150-NCS-TCP-UTIL diskette in the NCS/150 disk
drive, then press the Reset switch.

3.  After the NCS/150 has finished booting, press the following
sequence on the keyboard:

    <RETURN>.<RETURN>

Be sure to type the period (.) in the above sequence.

4.  Remove the SW/150-NCS-TCP-UTIL diskette, then insert the SW/
150-NCS-TCP diskette in the disk drive.  Enter the following
command:

    ls -lx /BIN

This command displays the list of software images currently
available on the SW/150-NCS-TCP diskette.

5.  Because the NCS/150 diskette can contain software images for
two product types only, it may be necessary to remove
software from the diskette to make room for the CS/200 file.
This can be done by typing "rm<filename>".

6.  If a cs200t file already exists, remove it by typing:

    rm /BIN/cs200t

7.  Perform a file system check with the compact option by typing
the following command:

    fsck -c

8.  Create a CS/200 file on the SW/150-NCS-TCP diskette using the
following command:

    cr /BIN/cs200t 1f4 rwx 101000

9.  To copy the file, type the following command:

    cr #0 /BIN/cs200t

10. When the system prompts for the source diskette, remove the
SW/150-NCS-TCP diskette.  Insert the SW/200-TCP-PKTGEN-NCS/
150 Version 20100 diskette in the disk drive.  Then press the
Return key.

11. When the system prompts for the destination diskette, replace
the SW/200-TCP-PKTGEN-NCS/150 Version 20100 diskette with the
SW/150-NCS-TCP diskette.  Then press the Return key.  The
copying process is finished when this message is displayed:

    copy completed

.h1;Testing Your Network

Use the following procedure to test your network with SW/200-TCP-
PKTGEN-NCS/150 Version 20100:

1.  Verify that the Series/200 product is bound to the NCS/150 on
which you have just installed SW/200-TCP-PKTGEN-NCS/150
Version 20100.

2.  Boot the Series/200 product from the NCS/150 according to the
procedure described in the Series/200 Installation Guide.

3.  Set the privilege level to global network manager using the
SET PRIvilege command.

4.  Assign ports 26 through 61 on the Series/200 product to a
rotary.  For example:

    rotary !128=!26-!61

5.  Assign an unused Internet address to the rotary defined in
step 4.  For example:

    setdefault (!128) ip=192.9.200.1

6.  From a terminal attached to a second Communications Server on
the network, make a connection to the address assigned in
step 5.  For example:

    connect 192.9.200.1

A welcome message is displayed on the screen.

7.  Press any key except the Break key on the terminal attached
to the second Communications Server.  The PKTGEN> prompt
appears on the screen.

8.  Begin transmission of test packets by typing the following
command on the terminal attached to the second Communications
Server.

    g

This command transmits packets from the Series/200 product
running SW/200-TCP-PKTGEN-NCS/150 Version 20100 via the
second Communications Server to the terminal from which the
command was entered.  Each packet is represented on the
screen by one line of data.  Data blocks, consisting of 22
lines of data and a header line, are transmitted every two
seconds.

If you wish to change this format, refer to the "Features"
section in this release memo for information on changing the
parameters in SW/200-TCP-PKTGEN-NCS/150 Version 20100.

Inspect the display on the terminal screen.  The characters
should line up in vertical columns.  Irregular rows and
columns indicate lost characters.

Let the packet generator run for at least one hour.  Test
results are most reliable if the transmission is allowed to
continue for several hours.  3Com recommends running the
tests for 24 hours in order to measure the effect of any
daily transcient factors (e.g., electrical machinery starting
in the morning on a business day) and to get a reference base
of error rates for your installation.

9.  To stop the tests, suspend transmission of test packets by
pressing the Break key.  Transmission of test pacekts may be
resumed by entering the command:

    g

10. After stopping the tests, return the terminal port to Command
mode by entering the ECMChar (usually <CTRL-^>).

11. Terminate the connection by entering the following command:

    dc

.h1;Features

SW/200-TCP-PKTGEN-NCS/150 Version 20100 has the following
features:

1.  Series/200 product users can connect to virtual ports 26
through 61 to run SW/200-TCP-PKTGEN-NCS/150 Version 20100.

2.  The format of data blocks generated by SW/200-TCP-PKTGEN-NCS/
150 Version 20100 can be modified by changing the values of
the parameters in SW/200-TCP-PKTGEN-NCS/150 Version 20100.

To display these parameters, press "?" at the PKTGEN> prompt.

The following list provides a brief description of each of
the parameters in SW/200-TCP-PKTGEN-NCS/150 Version 20100:

    a.  The "l" parameter determines the number of lines
        generated by each data block.

        For example, to transmit data blocks with 30 lines each,
        type the following at the PKTGEN> prompt:

        l 30

        The default value of this parameter is 22, and the
        possible values are 1 through 32767.

    b.  The "s" parameter determines the number of seconds
        between data block tranmissions.

        For example, to allow 5 seconds to elapse between data
        block tranmissions, type the following at the PKTGEN>
        prompt:

        s 5

        The default value of this parameter is 2, and the
        possible values are 1 through 32767.

    c.  The "h" parameter determines whether the data block is
        transmitted with or without a header.  The header is the
        first line of the data block and provides information
        regarding the date and server.

        For example, to transmit the data block without a header,
        type the following at the PKTGEN> prompt:

        h 0

        The default value of this parameter is 1, which transmits
        the data block with a header, and the possible values are
        1 or 0.

    d.  The "g" parameter determines the number of data blocks to
        be sent.

        For example, to send 50 data blocks, type the following
        at the PKTGEN> prompt:

        g 50

        The default value of this parameter is 0, which transmits
        data blocks until the user presses the Break key.  The
        possible values are 0 through 32767.

.h1;Known Problems

If users of SW/200-TCP-PKTGEN-NCS/150 Version 20100 enter
commands faster than the terminal can echo them, these commands
are lost.
