• Net/Subnet Mask Length—Type the subnet mask length (decimal number representing the subnet
mask length in bits) or click the arrows to adjust the subnet mask length. The subnet mask length is
the same for all ONS 15454 nodes in the same subnet.
TCC CORBA (IIOP) Listener Port—Sets the ONS 15454 IIOP listener port used for communication
•
between the ONS 15454 and CTC computers. This field is generally not changed unless the
ONS 15454 resides behind a firewall that requires a different port. See the
ONS 15454 for Firewall Access" procedure on page 3-23
Gateway Settings—Provisions the ONS 15454 SOCKS proxy server features. (SOCKS is a standard
•
proxy protocol for IP-based applications.) Do not change these options until you review the
"22.2.7 Scenario 7: Provisioning the ONS 15454 Proxy Server" section on page
proxy server networks, the ONS 15454 is either an ENE, a GNE, or a proxy-only server.
Provisioning must be consistent for each NE type.
• Enable SOCKS proxy server on port—If checked, the ONS 15454 serves as a proxy for connections
between CTC clients and ONS 15454 nodes that are connected by data communications channels
(DCCs) to the proxy ONS 15454. The CTC client establishes connections to DCC-connected nodes
through the proxy node. The CTC client does not require IP connectivity to the DCC-connected
nodes, only to the proxy ONS 15454. If the Enable SOCKS proxy server on port check box is
unchecked, the node does not proxy for any CTC clients. When this box is checked, you can
provision one of the following options:
Click Apply.
Step 3
Click Yes in the confirmation dialog box.
Step 4
Both TCC2/TCC2P cards reboot, one at a time. During this time (approximately 5 minutes), the active
and standby TCC2/TCC2P card LEDs go through the cycle shown in
connection, switching to network view" message appears.

External Network Element (ENE)—Choose this option when the ONS 15454 is not connected
–
to a LAN but has DCC connections to other ONS nodes. A CTC computer connected to the ENE
through the TCC2/TCC2P TCP/IP (craft) port can manage nodes that have DCC connections to
the ENE. However, the CTC computer does not have direct IP connectivity to these nodes or to
any LAN/WAN that those nodes might be connected to.
Gateway Network Element (GNE)—Choose this option when the ONS 15454 is connected to a
–
LAN and has DCC connections to other nodes. A CTC computer connected to the LAN can
manage all nodes that have DCC connections to the GNE, but the CTC computer does not have
direct IP connectivity to them. The GNE option isolates the LAN from the DCC network so that
IP traffic originating from the DCC-connected nodes and any CTC computers connected to
them is prevented from reaching the LAN.
SOCKS Proxy-Only—Choose this option when the ONS 15454 is connected to a LAN and the
–
LAN is separated from the node by a firewall. The SOCKS Proxy Only option is the same as
the GNE option, except that the SOCKS Proxy Only option does not isolate the DCC network
from the LAN.
