Chapter 19 DLPs D200 to D299

DLP- D249 Provision IP Settings

•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 SDH nodes in the same subnet.

•TCC CORBA (IIOP) Listener Port—Sets the ONS 15454 SDH IIOP listener port used to communicate between the ONS 15454 SDH and CTC computers. This field is generally not changed unless the ONS 15454 SDH resides behind a firewall that requires a different port. See the “NTP-D27 Set Up the ONS 15454 SDH for Firewall Access” procedure on page 4-8for more information.

•Gateway Settings—Provisions ONS 15454 SDH SOCK proxy server features. Do not select any of these options until you review the SOCKS proxy server scenario in the “Management Network Connectivity” chapter in the Cisco ONS 15454 SDH Reference Manual. In proxy server networks, the ONS 15454 SDH is either an ENE, a GNE, or a SOCKS proxy-only server. Provisioning must be consistent for each network element (NE) type.

•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:

–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.

Step 4 Click Apply.

Step 5 Click Yes in the confirmation dialog box.

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 Table 19-4. Eventually, a “Lost node connection, switching to network view” message appears.
