DLP- D249 Provision IP Settings
Enable proxy server on port—If checked, the ONS 15454 SDH serves as a proxy for connections
•
between CTC clients and ONS 15454 SDH nodes that are connected by DCCs to the proxy
ONS 15454 SDH. 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 SDH. If Enable SOCKS proxy server on port is off, 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 4
Click Yes in the confirmation dialog box.
Step 5
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
node connection, switching to network view" message appears.

External Network Element (ENE)—Choose this option when the ONS 15454 SDH 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 CRAFT or LAN 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 SDH 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 SDH is connected to a LAN
–
and the LAN is separated from the node by a firewall. The SOCKS Proxy Only is the same as
the GNE option, except the SOCKS Proxy Only option does not isolate the DCC network from
the LAN.
