Let’s explore the foundational setup that must be completed in Cisco DNA Center to ensure a seamless LAN automation process.

Network Hierarchy Setup: Building the Foundation for Network Management

At the heart of a successful LAN automation setup lies the Network Hierarchy configuration. This step is integral because it dictates how the network devices are organized within Cisco DNA Center, providing a logical structure to map physical devices to their respective locations. In essence, the Network Hierarchy defines how the devices are structured within the DNA Center framework, creating an intuitive view that simplifies future network management and troubleshooting.

This initial phase involves segmenting your network by physical locations, which could include data centers, campuses, branch offices, and other facilities. Within Cisco DNA Center, this is done by navigating to the Design tab and selecting Network Hierarchy, where you will assign network sites. These sites represent the various locations where your network devices will reside. For instance, you might create a “Data Center” site for your central data infrastructure or a “Campus” site for a particular office location.

By organizing your network into building and floor segments, you establish a hierarchy that can streamline troubleshooting efforts by allowing you to quickly identify which device is located where. This hierarchical structure also proves valuable when planning future network expansions, as it provides a roadmap for where devices should be placed and how they should be grouped for efficient management.

Defining Network Settings: Establishing Core Communication Framework

For instance, DNS (Domain Name System) settings are crucial for translating domain names into IP addresses, which enables devices within the The next essential step in preparing for LAN automation is configuring network services such as DNS, DHCP, NTP, and ISE servers. These network services serve as the backbone for seamless communication between Cisco DNA Center and the network devices it manages. Ensuring that these services are correctly configured not only enables smooth device provisioning but also guarantees that your network will function optimally once automation kicks in.

Orkkk to locate each other. DHCP (Dynamic Host Configuration Protocol) is equally important, as it automatically assigns IP addresses to network devices, ensuring that each device receives an address within the correct subnet. NTP (Network Time Protocol) ensures that time synchronization is maintained across the entire network, preventing issues with logs, certificate validity, and time-dependent tasks. Additionally, the ISE (Identity Services Engine) server configuration is essential for authenticating and authorizing devices that connect to the network.

To configure these services, simply head to the Design tab in Cisco DNA Center and select Network Settings. From here, you can input the required values for each service, ensuring that DNS, DHCP, and NTP servers are properly defined for your network’s communication needs.

Device credentials are particularly critical in an automated environment because they ensure that the process remains secure and seamless. They also provide a point of contact for troubleshooting or manually managing devices if needed. Therefore, setting up these credentials with the appropriate access levels and securing them properly within Cisco DNA Center forms the backbone of a successful LAN automation implementation.

Configuring IP Address Pools: Defining Address Allocation for Devices

The next key step in the process is configuring IP address pools. A well-organized IP address allocation scheme is essential for the successful automation of network devices. With LAN Automation, IP addresses are dynamically assigned to newly discovered devices as they are added to the network. However, this can only happen if IP address pools are well-defined and organized.

Begin by configuring a global IP pool at the highest level in Cisco DNA Center. This pool serves as a supernet for all your network sites, providing a larger pool of IP addresses from which specific subnets can be carved out for each device group or location. When creating or verifying this pool, ensure that it uses CIDR notation for efficiency and flexibility. Do not assign a gateway IP within the global pool, as this pool is not intended for direct routing but merely for IP address distribution.

Once the global IP pool is in place, move to the site-specific level. Here, you will reserve IP subnets for LAN Automation. These subnets will be used to allocate IP addresses to devices as they are discovered and provisioned during the automation process. Reserving specific address ranges for each site ensures that there are no conflicts when devices are assigned their respective addresses, and it helps with network management and troubleshooting as each device’s address can be traced back to a specific segment of the network.

Discover and Provision Seed Devices: Laying the Groundwork for Automation

Before diving into the full-fledged automation of the network, it’s essential to discover and provision seed devices. Seed devices are typically the border node switches, the entry points to your network, which will act as the initial devices for the LAN automation process. These devices need to be manually discovered and configured first, as they will serve as the anchor points for the rest of the network devices.

The manual discovery process involves adding these devices to Cisco DNA Center and ensuring they are connected and operational. Once these seed devices are provisioned, they will form the foundational devices for future automation tasks. DNA Center will use these devices as templates or anchors to automatically discover and configure additional devices in the network. This ensures that the rest of the network devices can inherit configurations, settings, and network services from the seed devices, simplifying the provisioning process and reducing the potential for human error.

By provisioning these seed devices first, you lay the groundwork for a smooth, automated roll-out of network devices. The success of LAN Automation relies heavily on these initial devices being correctly configured and operational, as they act as the central control points for the entire network.

Selecting Seed Devices for Discovery

The next key step in the LAN automation workflow involves selecting the seed devices that will serve as the foundation for discovering and provisioning access switches in the network. Seed devices are essentially the starting point for the automation process, from which the DNA Center will map the network’s fabric topology.

Once you’re in the LAN Automation dashboard, you will see an option to choose the site where your seed devices are located. The selection of the appropriate site is crucial, as it ensures that the correct geographical or logical grouping is applied. For example, a data center in one region might have a different network topology compared to a branch office in another location. After selecting the site, you’ll need to pick the seed devices that will serve as the basis for the automation.

There are two primary seed devices to choose from: the primary and secondary border node. These devices are critical for ensuring that network discovery is performed correctly. The primary seed device is typically the first point of contact for network traffic, while the secondary seed device is used for redundancy, ensuring that your network remains stable even if one device fails.

The interfaces on these seed devices must be selected carefully. These interfaces define how the access switches will connect to the fabric network, and ensuring the correct selection is vital for ensuring that the network topology is accurately reflected. Failure to select the right interfaces can lead to connectivity issues down the line, so administrators must double-check these choices to avoid errors.

Configuring the Secondary Seed Device

If your network design includes a secondary seed device, you’ll need to configure it similarly to the primary seed. This redundancy ensures that the fabric network is resilient and can continue to function even if one of the devices fails. The process for configuring the secondary seed is almost identical to that of the primary seed, with the additional step of confirming that the same interfaces are selected.

By ensuring that both the primary and secondary seed devices are correctly configured with matching interface selections, DNA Center guarantees that the network topology remains coherent across the entire fabric. The secondary seed device serves as a backup, providing high availability and ensuring that traffic can still flow smoothly even in the event of a failure.

The redundancy of having two seed devices is particularly valuable in larger, more complex network environments where uptime is critical. Organizations that rely heavily on continuous operations can rest assured that their network is designed for resilience, with automatic failover built into the LAN automation process.

Choosing IP Address Pools and Enabling Advanced Features

At this point in the workflow, you’ll be prompted to select the IP address pool for the LAN automation process. This pool is critical, as it defines the range of IP addresses that will be allocated to the discovered access switches. Typically, this pool is predefined during the network design phase, based on the network’s address plan.

Once the IP address pool is selected, administrators are given the option to enable advanced network features such as multicast and BGP advertisement. These features play a key role in ensuring that routing information is correctly propagated throughout the network, especially in larger networks with complex routing needs.

Enabling multicast ensures that routing information is distributed efficiently across the network, avoiding unnecessary traffic and reducing the potential for network congestion. By enabling BGP (Border Gateway Protocol) advertisement, DNA Center ensures that the LAN automation routes are advertised throughout the network, providing the necessary information to other routers and network devices.

These advanced features are essential for optimizing network performance, especially in large-scale environments where efficient routing and traffic distribution are crucial. The ability to configure these options directly in the automation process saves time and ensures that the correct settings are applied from the outset, reducing the need for manual configuration and troubleshooting later on.

Hostname Mapping and Final Review

Before the automation process begins, administrators are prompted to review the final settings. The last step involves configuring the hostname mapping for the access switches. Hostname mapping is critical for ensuring that each device on the network has a unique identifier, which makes it easier to manage, monitor, and troubleshoot.

In this step, you can either manually define a hostname prefix or upload a CSV file that maps serial numbers to hostnames. The prefix method is straightforward: DNA Center will assign a sequential name to each discovered switch, incrementing the names automatically. This method is convenient, especially in scenarios where the network contains a large number of devices.

Alternatively, administrators can opt to upload a CSV file, which contains a detailed mapping of serial numbers to hostnames. This is especially useful when dealing with existing hardware or when a more specific naming convention is required for organizational or administrative purposes. By uploading a CSV file, the process becomes even more efficient, reducing the amount of manual input required.

Once the hostname mapping is completed, the administrator can perform a final review of the settings to ensure that everything is correctly configured. This step serves as a verification process, where administrators can double-check their choices before initiating the automation. DNA Center will provide a summary of the configurations, including the selected seed devices, IP address pools, multicast settings, and hostname mappings.

If everything appears in order, the administrator can proceed to launch the automation process by clicking the Start LAN Automation button. At this stage, the system begins the process of discovering, configuring, and provisioning the access switches based on the selections made in the previous steps.
