Map a logical network to a physical interface¶

You may want to allocate specific network interfaces to handle different types of network traffic to achieve better performance in your OpenStack environment. Fuel enables you to modify mappings for your entire network, except for the Admin network for which you can make changes only during the Fuel Master node installation.

Network interface mapping can be modified after you deploy an OpenStack environment. The net-config task updates the networking configuration.

To map a logical network to a physical interface:

1. In the Fuel web UI, click Nodes.
2. Select a node.
3. Click Configure Interfaces.
4. Drag and drop a logical network to the corresponding physical interface or bond.
