12.2.9 Scenario 9: IP Addressing with Secure Mode Enabled
Figure 12-15 shows a network with dual GNEs on different subnets.
Figure 12-15 Scenario 8: Dual GNEs on Different Subnets
12.2.9 Scenario 9: IP Addressing with Secure Mode Enabled
TCC2/TCC2P cards provide a secure mode option allowing you to provision two IP addresses for the
ONS 15454. One IP address is provisioned for the ONS 15454 SDH MIC-C/T/P LAN port. The other IP
address is provisioned for the TCC2/TCC2P TCP/IP craft port. The two IP addresses provide an
additional layer of separation between the craft access port and the ONS 15454 SDH LAN. If secure
mode is enabled, the IP addresses provisioned for the TCC2/TCC2P TCP/IP ports must follow general
IP addressing guidelines. In addition, TCC2/TCC2P IP addresses must reside on a different subnet from
the ONS 15454 SDH MIC-C/T/P port and ONS 15454 SDH default router IP addresses.
The IP address assigned to the MIC-C/T/P LAN port becomes a private address, which is used to connect
the ONS 15454 SDH GNE to an OSS (Operations Support System) through a central office LAN or
private enterprise network. In secure mode, the MIC-C/T/P LAN IP address is not displayed on the CTC
node view or to a technician directly connected to the node by default. This default can be changed to
allow the MIC-C/T/P IP address to be displayed on CTC only by a Superuser.
