DLP- D84 Enable Node Security Mode
• External Network Element (ENE)—If selected, the CTC computer is only visible to the
ONS 15454 SDH to which the CTC computer is connected. The computer is not visible to the
DCC-connected nodes. In addition, firewall is enabled, which means that the node prevents IP traffic
from being routed between the DCC and the LAN port.
• Gateway Network Element (GNE)—If selected, the CTC computer is visible to other
DCC-connected nodes. The node prevents IP traffic from being routed between the DCC and the
LAN port.
Note The SOCKS proxy server is automatically enabled when you enable secure mode.
Step 9 Click Finish.
Within the next 30 to 40 seconds, the TCC2P cards reboot. CTC switches to network view, and the CTC
Alerts dialog box appears. In network view, the node changes to grey and a DISCONNECTED condition
appears.
Step 10 In the CTC Alerts dialog box, click Close. Wait for the reboot to finish. (This might take several
minutes.)
Step 11 After the DISCONNECTED condition clears, complete the following steps to suppress the MIC-C/T/P
IP address from display in CTC and the LCD. If you do not want to suppress the MIC-C/T/P IP address
display, continue with Step 12.
a. Display the node in node view.
b. Click the Provisioning > Security > Data Comm tabs.
c. In the LCD IP Setting field, choose Suppress Display. This removes the IP address from display on
the ONS 15454 SDH LCD.
d. Check the Suppress CTC IP Address check box. This removes the IP address from display in the
CTC information area and from the Provisioning > Security > Data Comm tab.
e. Click Apply.
Note After you turn on secure mode, the TCC2P IP address becomes the node IP address.
Step 12 Return to your originating procedure (NTP).
