Data Comm
(ONS 15454 SDH with TCC2P cards only; Superusers only) Use this tab to manage the TCC2P security mode function. When security mode is enabled, two IP addresses are assigned to the node. One address is assigned to the MIC-C/T/P LAN port and the other to the TCC2P RJ-45 TCP/IP (LAN) port. Security mode can be enabled and not locked, which allows security mode to be disabled at a later point. Security mode can also be permanently locked. If it is locked, no provisioning can be performed from this tab.
Note
MIC-C/T/P Ethernet Port fields appear when security mode is enabled and unlocked.
 
Item
Description
TCP/IP Mode
Indicates the current security mode status:
 •
Normal: Security mode is not enabled; one IP address is assigned to the node.
 •
Secure: Security mode is enabled; two IP addresses are assigned to the node. Security mode will either be not locked or permanently locked. If it is locked, no provisioning can be performed.
Change Mode
Displays a wizard that allows you to perform two actions:
 •
If the TCP/IP mode is Normal, allows you to enable security mode.
 •
If TCP/IP mode is enabled but not locked, allows you to disable security mode.
Note
To start this wizard, a TCC2P card is required in the active slot. If using a standby slot, it must also contain a TCC2P card. The node must not already be in secure mode.
IP Address
The IP address assigned to the ONS 15454 SDH MIC-C/T/P port.
Mac Address
(Display only) The address of the node as it is identified on the Media Access Control layer of the network architecture.
LCD IP Setting
Provisions the display of the MIC-C/T/P IP address on the ONS 15454 SDH LCD:
 •
Allow Configuration—Displays the MIC-C/T/P IP address on the LCD and allows it to be changed using the LCD buttons.
 •
Display onlyDisplays the MIC-C/T/P IP address on the LCD but does not allow it to be changed using the LCD buttons.
 •
Suppress Display—Suppresses the display of the IP address on the LCD
Net/Subnet mask length
Provisions the IP address subnet mask.
Default Router
The IP address of the default router. The default router enables packets to be sent from network elements that do not have direct access to the ONS node.
Suppress CTC IP Display
If checked, suppresses display of the MIC-C/T/P IP address from the CTC information area and on the Data Comm tab.
Note
Checking this option does not suppress the MIC-C/T/P IP address display for Superusers.
IPv6 Configuration
Displays the IPv6 configuration details.
Enable IPv6
If checked, enables IPv6. The node runs IPv4 by default.
IPv6 Address
Sets the defined unicast IPv6 address to the node.
Prefix Length
Sets the prefix length for the provisioned IPv6 address. The value must be between 0 to 128.
Note
This field is disabled if the Enable IPv6 check box is not selected.
IPv6 Default Router
Sets the IPv6 default router address.
Note
This field is disabled if the Enable IPv6 check box is not selected.
Apply
Applies changes made to the MIC-C/T/P Ethernet port fields.
Reset
Cancels any Data Comm subtab changes and returns the fields to their last-saved settings.
Help
Displays context-sensitive help.
