Introduction

Dynamic Host Configuration Protocol (DHCP) plays a pivotal role in modern networking by automating the assignment of crucial network parameters such as IP addresses, subnet masks, gateways, and DNS servers. This automation ensures that devices can seamlessly connect to the network without manual configuration. In the Aruba AOS8 environment, configuring DHCP services is an indispensable task for network administrators. This process is essential to maintain seamless connectivity, optimize network performance, and ensure efficient management of IP address resources.

Overview of DHCP in Aruba AOS8

Aruba AOS8 is a robust and flexible network operating system that incorporates integrated DHCP services directly into its architecture. This integration empowers network administrators to manage IP address assignments directly from Aruba Mobility Controllers, dispensing with the need for separate, dedicated DHCP server hardware. The integrated DHCP server in Aruba AOS8 is adept at providing IP addresses to clients connecting to the network, which streamlines operations and enhances the overall efficiency of network management.

Configuring DHCP Scopes

A DHCP scope defines a specific range of IP addresses that the DHCP server is authorized to allocate to clients on the network. Configuring DHCP scopes in Aruba AOS8 involves several critical steps, including defining IP address pools and configuring the parameters that clients will receive when they are assigned an IP address.

Step-by-Step Configuration

1. Access the Mobility Controller:

   • Begin by logging in to the Aruba Mobility Master or a standalone Mobility Controller. This can be done through the web-based Graphical User Interface (GUI) or the Command Line Interface (CLI), depending on your preference and familiarity.

2. Navigate to the DHCP Configuration:

   • Within the web GUI, proceed to Configuration > System > Profiles > DHCP. This path will take you to the section where DHCP settings can be configured.

3. Create a New DHCP Pool:

   • Click on the ‘Add’ button to initiate the creation of a new DHCP scope. Provide a descriptive name for the DHCP pool that aligns with its intended use.

4. Define the IP Address Range:

   • Specify the start and end IP addresses for the DHCP scope. Ensure this range falls within the subnet designated for the specific VLAN or network to prevent conflicts.
