Modify Management and API Access Networks

If you deployed the management network and API access network without DHCP, you can add IP address ranges and change DNS servers after deployment.

Networks that use DHCP cannot be modified.

Procedure

1. Log in to the Integrated OpenStack Manager web interface as the admin user.
2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
3. On the Network tab, select the network that you want to modify.
   • To add an IP address range, select Add IP Range and enter the IP address range that you want to add to the network.

     In the dialog box displayed, you can click Add IP Range again to add multiple IP address ranges at once.

     Important: The management and API access networks cannot include more than 100 IP addresses each.
   • To change the DNS server, select Change DNS and enter the DNS servers that you want to add to the network.

     Modifying the DNS settings will briefly interrupt the network connection.
