In this configuration, the communications between the two PCs are taking place “in the clear”,
without encryption enabled. (The “
Encrypting
” LEDs on the SE-6600 units will be off.) The
next step will turn link encryption on.
10:
With the LAN cable still connected to SE-6600 B, open the web browser and enter
(the new IP address from Step 7). Click on
Cipher Config
from the menu of
SE-6600 B to display the screen shown in Figure 3, and this time, click on the red rectangle
which reads, “
Enable Block Mode Cipher
”.
This not only activates the encryption on the SE-
6600 B unit, but also sends a message to SE-6600 A to do the same
. An
Enabling Block Mode
Cipher
screen will appear, with a message to wait while the action takes place. (Note that SE-
6600 A could have been used to send the message to SE-6600 B instead.)
Now the “
Encrypting
” LEDs on the SE-6600 units will be lit, and the terminal-to-terminal
communications described in Step 9 should once again be possible.
Clicking on
Port Activity
from the menu displays a screen similar to that shown in Figure 6
below. Whenever either PC sends terminal messages to the other, the
Serial
counters will
increase, but the
Network
counters will also increment due to the SE-6600 units communicating
with each other, even in the absence of terminal activity.
