Tasks
Creating a DHCPv4 network.
Restarting Grid services.
Task 1: Creating a DHCPv4 network
The IPv4 network that has been provisioned for this location is 172.31.111.0/24, with the default gateway 172.31.111.1. Shortly, more provisions will be done so DHCP service is provided by the member ibns1.techblue.net.
Task 2: Restarting Grid services
After saving changes, you should be prompted to restart services. If not, please manually restart services.
Solutions
Task 1 Solution: Creating a DHCPv4 network
Create the DHCP Network 172.31.111.0/24 and set 172.31.111.1 as the default gateway for this network.
Navigate to Data Management → DHCP → Networks → Networks
Click the Add dropdown menu and select IPv4 Network
Select the radio button for Add Network

Click on the link for ibns1.techblue.net from the Member Selector window
Click Next after the Member info is populated
At Step 4 of 7, click the Override button in the section for Routers (this will change the button color to black and the button will now say Inherit)
Click the IP Address field in the Routers section
Enter the IP address for the router on this network – 172.31.111.1
Click Save & Close to save changes
Task 2 Solution: Restarting Grid services
Changes made to the DHCP configuration during Network creation only take effect after a service restart.
Restart the DHCP Service by clicking the Restart button in the notification banner at the top of Grid Manager
At the Restart Grid Services window, click Restart
Alternatively, we can also restart services from the Members menu.
Navigate to Grid → Grid Manager → Members
Place a checkmark in the box beside ibns1.techblue.net
