DLP-G56 Provision IP Settings
Default Router—If the ONS 15454 must communicate with a device on a network that the
•
ONS 15454 is not directly connected to, the ONS 15454 can forward the packets to the default
router. Type the IP address of the router in this field.
Note
Forward DHCP Request To—Check this check box to enable DHCP. Also, enter the DHCP server
•
IP address in the Request To field. Unchecked is the default. If you will enable any of the gateway
settings to implement the ONS 15454 proxy server features, leave this field blank.
Note
MAC Address—(Display only.) Displays the ONS 15454 IEEE 802 MAC address.
•
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 15454s in the same subnet.
• TCC CORBA (IIOP) Listener Port—Provisions the ONS 15454 IIOP listener port. This listener port
enables communication with the ONS 15454 through firewalls. See the
ONS 15454 for Firewall Access" procedure on page 3-19
Gateway Settings—Provides options that enable the ONS 15454 proxy server features. In proxy
•
server networks, the ONS 15454 is either an end network element (ENE), gateway network element
(GNE), or proxy-only server. GNEs and ENEs manage their craft Ethernet ports differently. A GNE
will connect to an entire intranet or internet through its craft Ethernet port. An ENE will only
communicate with the hosts that have connected to it, such as a CTC computer or other
ONS 15454 ENE. Provisioning must be consistent for each NE type. For more information, see the
"19.2.7 Scenario 7: Provisioning the ONS 15454 Proxy Server" section on page
Enable proxy server on port—If checked, the ONS 15454 serves as a proxy for connections between
•
CTC clients and ONS 15454s that are DCC-connected to the proxy ONS 15454. The CTC client
establishes connections to data communications channel (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 Enable proxy server on port is off, the node does not proxy for any CTC
clients, although any established proxy connections continue until the CTC client exits. When this
box is checked, you can set the node as an ENE or a GNE:

– Allow Configuration—Displays the node IP address on the LCD and allows users to change the
IP settings using the LCD. This option enables the
Router, and Network Mask Using the LCD" task on page
Display Only—Displays the node IP address on the LCD but does not allow users to change the
–
IP address using the LCD.
Suppress Display—Suppresses the node IP address display on the LCD.
–
This field is ignored if the node is not connected to a LAN, or if you enable any of the
gateway settings to implement the ONS 15454 proxy server feature.
If you enable DHCP, computers connected to an ONS 15454 node can obtain temporary IP
addresses from an external DHCP server. The ONS 15454 only forwards DHCP requests; it
does not act as a DHCP server.
End Network Element (ENE)—If selected, the CTC computer is only visible to the ONS 15454
–
to which the CTC computer is connected. The computer is not visible to other 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.
