2570 - Configuring DHCP Services in BloxOne DDI

Scenario

The DHCP service needs to be enabled on two BloxOne Hosts before we begin to configure DHCP services. Then we need to plan Global Options and configure an initial DHCP Config Profile for the DHCP clients to use.

Estimated Completion Time

  • 15 to 20 minutes

Prerequisites

  • Administrative access to the CSP

  • Lab 2801: Deploying BloxOne Hosts

Course References

  • 2170 DHCP Services

Tasks

  1. Enabling a DHCP service Instances for BloxOne Hosts 'oph1' and  'oph2'

  2. Creating an Option Group for Techblue NYC Branch

  3. Configuring the DHCP Config Profile for Techblue NYC Branch

  4. Applying the DHCP Config Profile to a Service Instance

Task 1: Enabling DHCP service instances for BloxOne Host oph1 and oph2  

A DHCP service instance needs to be created for two BloxOne Hosts, oph1.techblue.net and oph2.techblue.net. Name the services Techblue DHCP service 1 and Techblue DHCP service 2 per the table below:

Table 2570-1

Host IP Address

Host Name

Service Name

10.100.0.110

oph1.techblue.net

Techblue DHCP service 1

10.200.0.110

oph2.techblue.net

Techblue DHCP service 2

Task 2: Creating an Option Group for Techblue NYC Branch

We'll need an IPv4 Option Group to offer specific options to any clients getting an IP address from the Techblue NYC Branch service instance. Create an IPv4 Option Group named Techblue NYC Branch using the specifications from the following table:

Table 2570-2

Type

Space

Name (code)

Value(s)

Option

DHCPv4

domain-name-servers (6)

10.100.0.110,10.200.0.110

Option

DHCPv4

domain-name (15)

techblue.net

Option

DHCPv4

ntp-servers (42)

10.100.0.10

Option

DHCPv4

routers (3)

172.31.101.1

Task 3: Configuring the DHCP Config Profile for Techblue NYC Branch

We want to use our new Option Group with the Techblue NYC Branch DHCP clients, and we want to be able to designate specific settings for the Techblue NYC Branch DHCP service that may differ from the Global Configuration. We can do this with a DHCP Config Profile. Create a new DHCP Config Profile named Techblue NYC Branch with a short lease time of 4 minutes to account for some DHCP client testing. We also want to allow leases for unknown clients. For DHCP Options, we want to use the IPv4 DHCP Option Group we created called Techblue NYC Branch.

Task 4: Applying the DHCP Config Profile to a Service Instance

Our DHCP Config Profile has not been applied to any DHCP services yet. Apply the DHCP Config Profile to the Service Instances we started, Techblue DHCP service 1 (but not Techblue DHCP service 2 yet).



Solutions

Task 1 Solution: Enabling DHCP service instances for BloxOne Host oph1 and oph2  

  1. On the Jump-Desktop, open your CSP browser window and navigate to ManageInfrastructure Services

  2. Click on Create Service and choose DHCP from the drop-down

  3. Enter a Name: Techblue DHCP service 1

  4. Click on Select Host and locate the BloxOne Host with the IP address 10.100.0.110 (this should be oph1.techblue.net)

  5. Select the Host and click on the Select button on the right

  6. Click Next and confirm this is the right IP Address of the Host

  7. Click Finish and then Save & Close

  8. Repeat all steps above, but use the name Techblue DHCP service 2 and locate the Host with the IP address 10.200.0.110 (oph2.techblue.net).

  9. Refresh the page until you see each service indicates Online.

When starting, the Service Status will change from Stopped to Online. It may also indicate Error in this process. It may take 3 to 5 minutes for the service to show as Online. If the service remains stopped, attempt to restart it by selecting the checkbox for the service and choosing Restart from the Service Actions drop-down menu.
