2.1  Network ID and IP Configuration Requirement

Table 2-1 lists the configuration requirements of network ID and IP.


Table 2-1 Network ID and IP configuration requirements

Type

Requirements

ID

In the networks managed by one NM, the ID of each NE is unique.

In a ring network, the ID of NE should increase one by one along the direction of the primary ring.

The ID of main subrack should be allocated prior to that of extension subrack.

In a complex network, the ID of stations on ring should be allocated before that on chain. For example, if the ID on ring is 1 to N, the ID on a chain should be N+1, N+2¼

When adding NE, the IDs of existing NEs remain unchanged. The ID of new NE increases along the primary ring on condition that it is unique.

IP

An IP address is necessary for gateway NE and is optional for non-gateway NE.

The default subnet is 129.9.0.0. Subnet mask is 255.255.0.0.

The IP address of NE needs not to be set manually, because it varies with ID.

2.2  Intelligent Application Configuration Requirement

Perform the operation required below before enabling the intelligent features of the OptiX OSN 9500.

Table 2-2 Intelligent application configuration requirements

No.

Requirements

1

Each NE should load and enable the intelligent software. If there is no application requirement, the intelligent software may remain disabled by default.

2

The node ID of the NE with intelligent feature must be unique in a network. The ID cannot be changed after the intelligent service is configured.

3

The node IP address is 1.1.1.N. N refers to the Node ID, which can be the same with the NE ID or not.

The subnet mask is 255.255.0.0.

4

In a hybrid network comprising intelligent NE and non-intelligent NE, only static services can be configured. That is, the network has no intelligent features.

2.3  Board Configuration Requirement

2.3.1  Cross-Connect Board

Configure a cross-connect board depending on the service capacity and the increase tendency. Select the cross-connect board based on the requirements in Table 2-3.

2.3.2  SDH Board

1.  Slot Requirement

Figure 2-1 shows the slot access capacity with GXCH configured. The access capacity of each slot is variable with the actual configuration. Table 2-4 shows the correspondence between 20 G slots and 5 G slots. Follow the rules below when configuring SDH board:

n  The total capacity of boards in each group shown in Table 2-4 cannot exceed 30 G. The capacity of the first slot is no more than 20 G, and that of the latter two slots is no more than 10 G.
