Initiate lab

To initiate the lab, double-click the Launch Lab icon on the Desktop.

Choose the lab number from the list and click OK.

After clicking OK, you will see a pop-up message with a brief description of the lab task. If the description looks correct, click Yes to continue lab initiation.

Lab initiation will take a couple of minutes to finish.

Once complete, you will see another pop-up message with the login credentials and the URL for the Grid Manager’s User Interface. Note that the credentials may differ from those from prior labs.

Tasks

1. Creating a DHCPv4 network.

2. 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.
