9.1 Overview The DCC is used to transmit the OAM (operation, maintenance, and administration) data between WDM equipments. The protocol stacks used by different vendors are not compatible with each other. Thus, extra overhead bytes or service resources must be allocated to transmit DCC data transparently in a network composed of multi-vendor products.

The IP over DCC meets most of the networking requirements in existing networks without occupying extra overhead bytes or service resources. The IP over DCC simplifies the network structure, saves network resources, and meets the networking requirements quickly.

The IP over DCC supports the following features:

Adopts the standard TCP/IP protocol, which makes it be compatible with other vendor’s equipment and simplifies the network management.

Adopts the forwarding function of the third layer in the protocol stack, which makes that extra overheads or service paths are unnecessary.

Brings flexible networking models. Brings simple upgrade modes and great compatibility. It is easy for IP over DCC to work

with new forwarding or multi-protocol features on the application layer.

IP over DCC provides two remote accessing modes.

Gateway NE mode

IP over DCC also provides the gateway NE mode for remote access. The ECC protocol is used. For remote access, log in to the GNE that is connected to the computer. Then other NEs can be accessed through the NE ID.

Direct connection mode

The IP over DCC feature is used, and the remote NE can be connected directly through the IP address. You just need to enter the destination IP address in the login interface. For this mode, however, you need to add in advance the static route or default gateway in the network NM (T2000) and the NE that needs to be accessed directly.

For details on IP Over DCC, refer to the OptiX BWS 1600G Backbone DWDM Optical Transmission System Product Description.



9.2 Basic Operation Stage Task

Setting NE Communication Parameters

Setting the parameters such as default gateway of the NE

Configuring Static Routes Configuring static routes and specifying the forwarding NE

9.2.1 Setting NE Communication Parameters For the NE that realizes communication through IP Over DCC, the NE communication parameters must be configured. The parameters are not required on the NE that realizes communication through ECC.

Prerequisites You must be an NM user with "NE and network maintainer" authority or higher.

Procedure Step 1 Double-click the ONE icon on the Main Topology. The Slot Layout tab is displayed.

Step 2 Right-click the subrack NE icon and select NE Explorer.

Step 3 In the NE Explorer, click the NE and choose Communication > Communication Parameters from the Function Tree.

Step 4 Refer to Table 9-1 to set NE communication parameters according to the actual plan. Enter values in the IP address, Gateway IP, and Subnet Mask fields.

IP is the IP of the NE. Extended ID is the eight most significant bits in the 24 bits of the NE. It indicates different subnets. Gateway IP is different from IP. It is not the IP address of the NE. It is the IP address of the router that is used to realize TCP/IP communication when the NE accesses the NM or NE in a remote end.

Step 5 Click Apply.

----End

9.2.2 Configuring Static Routes For the NE that realizes communication through IP over DCC, a static route is required between the gateway and the NE.

Prerequisites You must be an NM user with "NE and network maintainer" authority or higher.


Configuration Guide


Procedure Step 1 Right-click the NE icon on the Main Topology, and then select NE Explorer.

Step 2 Select the desired NE from the object tree. Then choose Communication > IP Stack Protocol Management from the Function Tree.

Step 3 Click the IP Route Management tab.

Step 4 Click New. Configure the following parameters in the Create an IP Route dialog box.

Destination Address: the IP address of the NE that requires communication Gateway IP: the IP address of the forwarding NE

Step 5 Click Apply.

----End

9.3 Parameters Table 9-1 NE communication parameters

Field Description

IP The IP address of an NE. After the IP address is set manually, any ID address change will no longer affect the IP.

Extended ID

The eight most significant bits in the 24 bit of the NE, also called the subnet number, used to identify different subnets.

Gateway IP For NEs communicating with the T2000 through IP over DCC protocol, gateway IP is the IP address of the NE with routing function.

Subnet Mask

The network mask code of the subnet where an NE resides, used to identify the network segment where an NE resides.

NSAP Address

Includes domain address and NE SYSID. The domain address is editable, which can be 26 hexadecimal digits at most. This parameter gives no contribution in the configuration of IP Over DCC.



9.4 Application This section describes four applications based on the four modes in which the NM communicates with the NE.

9.4.1 Application 1: in Gateway NE Mode If the T2000 and the GNE connect to the same Ethernet (the T2000 and the GNE must be in the same subnet), and other NEs are accessed in the gateway NE mode, you need not to add any static routes.

As shown in Figure 9-1, the T2000 with the IP address of 129.9.0.100 uses the nearby NE1 as the GNE to access other NEs. You need not to add static routes on the T2000 or NEs.

For details on how to create a gateway NE, refer to Chaper2 “Creating a Network”.

9.4.2 Application 2: in Gateway NE Mode (by Default Gateway) If the T2000 connects with the GNE through a router and other NEs are accessed in the gateway NE mode, you need to add a default gateway on the T2000 and on the GNE.

As shown in Figure 9-2, the T2000 with the IP address of 10.100.11.12 connects with the GNE (NE1) through a router and accesses other NEs in the gateway NE mode. In this case, you need to set a default gateway on both the T2000 and NE1. Set the default gateway on the T2000 to 10.100.11.1, and that on NE1 to 129.9.0.254.

9.4.3 Application 3: in Direct Connection Mode (by Static Routes) If the T2000 and the GNE connect to the same Ethernet and other NEs are accessed in the direct connection mode, you need to set on the T2000 the default gateway to the IP address of the NE that is connected to the T2000 directly. Or you need to add the static route to the non-GNEs, with the forwarding address as the IP address of the GNE.

As shown in Figure 9-3, if the T2000 with the IP address of 129.9.0.100 needs to access NE3 directly, you need to add the static route to 133.168.0.0/24 on the T2000.

Adding the static route to 133.168.0.0/24 indicates that the static routes in the whole network section 133.168.0.0/24 are added. Hence, the T2000 with the IP address of 129.9.0.100 can directly access the NE that belongs to the network section, such as NE2, NE3 and NE4.

This section describes only the configuration of the static routes of computer.

Step 1 Click Run in the Start menu on the T2000 computer in Windows platform. Enter cmd and the cmd.exe window is displayed.

Step 2 Enter the following command:

route add 133.168.0.0 mask 255.255.255.0 129.9.0.1

The format of the command used to add a static route on Windows computer is as follows: route add <Destination Address> mask < Subnet Mask > <Gateway IP>.



Step 3 Press Enter.

Step 4 (Optional) Enter the command “route print” in the cmd.exe window and press Enter. Then you can view all the created static routes. The created routes are displayed on the interface.

----End

9.4.4 Application 4: in Direct Connection Mode through a Router(by Static Routes)

The T2000 connects to the Ethernet port of a certain NE through a router and accesses other NEs in the direct connection mode. You need to:

Set on the T2000 the static route to the GNE and non-GNEs. Set on the GNE the default route to the T2000. Add static routes to the T2000 on the destination site and all the intermediate sites.

As shown in Figure 9-4, the T2000 with the IP address of 10.100.11.12 connects to NE1 through a router and accesses NE3 in the direct connection mode. Suppose the IP address of the T2000 is 10.100.11.0 (subnet mask 255.0.0.0). You need to:

Add the static route on the T2000 to the gateway 129.9.0.1. Add the static route on the T2000 to the others NEs.

Set the default gateway on NE1 to 129.9.0.254. Add the static route on NE2 to 10.100.11.0, with the next hop address as 129.9.0.1. Add the static route on NE3 to 10.100.11.0, with the next hop address as 133.168.0.1.
