Introduction

In the topology edit mode, you can build and adjust the network architecture by dragging, dropping, and deleting network devices (including virtual switches, routers, and NFV devices) and VMs, and configuring device connections.

Constraints and Restrictions

• The topology edit mode is available only to the administrator (admin). Tenants do not have permission to edit the topology.

• Ensure that the configured device connections are logically correct (for example, VMs must be connected to virtual switches, and routers must be connected to virtual switches or edges). Otherwise, the configuration cannot be saved.

• To delete a device from the topology, delete all its network connections (such as connections to VMs and virtual switches) first. Otherwise, the deletion will fail.

Prerequisites

• You have logged in to SCP using the admin account.

• A resource pool has been created and is running normally.

• The network devices (virtual switches, routers) and NFV devices to be deployed have been created, or the corresponding device templates have been uploaded.

Precautions

• It is recommended to take a screenshot to back up the current topology before editing, preventing configuration loss caused by misoperations.

• Configure the critical parameters of a device (such as the port group of a virtual switch) immediately after it is dragged to the topology canvas. Otherwise, network connectivity may be affected.

• To avoid configuration conflicts, do not edit the topology simultaneously with others.

Steps

Step 1.Log in to SCP and go to Networking > Topology.

Step 2.Click Edit in the upper-left corner to enter the topology edit mode. (The following message is displayed on the page: The topology has been changed. Click Apply Changes to save the changes.)

Step 3.Deploy network devices: Drag devices such as Virtual Switch, Router, and NGAF from the left pane to the topology canvas. Drag Virtual Machine to the canvas to complete the business node deployment.

Step 4.Configure device connections: Click the Add Connection button above the topology canvas and draw a line to connect a device (such as a VM) to another device (such as a virtual switch). In the Select Interface pop-up window that appears, select the interface (such as the eth0 interface of the VM) for connection. Repeat the operations to create a complete network link (Example: VM -Virtual Switch - Router - Edge).

Step 5.Save configuration: Click Apply Changes at the top of the canvas. In the pop-up window that appears, click OK to save and apply the changes, or click Cancel to discard the changes and exit the edit mode.

Step 6.Click Exit in the upper-left corner to exit the topology edit mode and view the modified topology.
