Overview

This topic describes how you can manage the assignment of IPv4 addresses to logical networks at system project level by using the LOGICAL NETWORK VIEW.

Modifying IP Addresses

To modify an IP address, double-click it and enter the new value.

You cannot modify an IP address in the LOGICAL NETWORK VIEW if the corresponding attribute is read-only when accessed from the PROPERTIES pane.

NOTE: The syntax of the IP address and its validity in relation to the logical network are checked. If the status is invalid, you can let the software assign a new valid IP address to the interface by using the corresponding context menu command. The uniqueness of the IP address is verified when you analyze the system project.

Rules When Changing Assignments to Logical Networks

The table describes the rules that apply when you move an interface to a new logical network in the LOGICAL NETWORK VIEW.

Scope

Description

Selection of devices

You can select one or more interfaces belonging to the same or different logical networks.

When you select an interface that is associated to another one (for example, because the IP addresses must belong to the same logical network) and move it to a new logical network, the associated interface is automatically moved to the same network. (For example, when you move only the MainIP address of a PAC, IPA is moved too. In case of a redundant PAC, MainIP+1 and IPB are moved as well.)

Target logical network

You can drag your selection to the logical network group or onto the list of interfaces inside the group. The result is the same in terms of IP address assignment.

IP address assignment

The interface that you move to a new logical network is automatically assigned the next available IP address on this network. The values of the corresponding attributes of the interface are updated.

If there are not enough IP addresses available in the target logical network, the action is canceled and a notification displayed.

Modifying Logical Networks

When you modify the subnet address or subnet mask of a logical network to which interfaces are assigned, the software verifies the validity of each IP address in relation to the new logical network data and updates its status in the corresponding column of the LOGICAL NETWORK VIEW. If the status is invalid, you can let the software assign a new valid IP address to interfaces by using the corresponding context menu command.

Assigning IP Addresses by Logical Network

To assign one or more IP addresses by logical network, proceed as follows.

Step

Action

1

In the LOGICAL NETWORK VIEW, select one or more interfaces in the NOCONF node.

Result: Your selection is highlighted.

NOTE: Your selection can also include one or more interfaces that are already assigned to a logical network if you want to reassign them to another logical network.

2

Drag your selection to a logical network

Result: The interfaces now belong to this logical network and each IP address is replaced by the next available address on this network.

Clearing Assignments to Logical Networks

To clear the logical network assignment for one or more interfaces, select them, and drag your selection to the NOCONF node.

The logical network and IP address information is cleared.
