Welcome back to catalyst capsules. I'm pleased to continue our journey from episode one, where we focused on preparing for engagement. Today we're delving into episode two titled Discovery and Foundation. This session is all about rolling up our sleeves and beginning the groundwork for network integrations.00:02Let's proceed to understand how we can effectively bring our network into the catalyst center. In today's session, we'll start by discussing why discovery serves as the foundational element in every Catalyst Center deployment. Next, we'll outline the prerequisites you'll need before launching into the process and then explore the different methods available.00:19For discovery. Following this, we'll transition to a live demonstration where I'll guide you through executing a real world discovery within Catalyst Center step by step. Finally, we'll conclude with insights on validating your inventory and tips to circumvent common pitfalls. Let's dive right in.00:39Discovery is pivotal as it allows Catalyst Center to understand your network. It's the primary technical step and the foundation for all subsequent activities without an effective discovery process, functionalities like automation, assurance, and template deployment are not feasible. Discovery compiles your inventory, which lists all devices Catalyst Center will.00:56Manage. When done correctly, the rest of the engagement unfolds seamlessly, otherwise. It could lead to extensive troubleshooting. Let's ensure we get it right. Before initiating discovery, there are crucial elements you need to have on hand.01:16Firstly, ensure you have your device IP addresses, at least a range that encompasses thems. Secondly, SNMP credentials are necessary. Either community strings for version two C or full SNMPV three credentials. Thirdly, CLI credentials, which include an SSH username.01:32And password for accessing device configurations are required. Lastly, ensure your network is reachable verifying that routing and firewall configurations permit catalyst center access. Preparing these will streamline the discovery process significantly.01:52Catalyst Center supports three principle discovery methods. The most commonly used is the IP range method, where a list of IP addresses is scanned directly, offering precision and discovery. For Cisco only environments lacking a complete IP inventory. The Cisco Discovery protocol, CDP is effective. Discovering all devices.02:08Connected to a specified seed device, the link layer discovery protocol, LLDP, serves a similar purpose but is vendor neutral, making it suitable for mixed vendor setups. Generally, we begin with the IP range method using documented device lists to ensure accuracy.02:28Welcome to another segment of catalyst capsules. Today we will guide you through the initial technical step of the DNAC engagement. Discovering devices. Our objective is to identify two wireless LAN controllers, five access points, and 20 network devices using Cisco Catalyst Center. Begin by.02:46Logging into the catalyst center. At the login screen, enter your administrator credentials upon successful authentication. You'll access the main dashboard, offering a high level view of your network's health, inventory, and assurance metrics. From the dashboard, go to the top left menu and select tools, then click on discovery. This section is the hub for.03:05Creating managing and monitoring all discovery tasks.03:25To initiate a new discovery job, click the add Discovery button located in the upper right corner. This will bring up the discovery configuration page where you can define how Catalyst Center will detect devices on your network. Start by assigning a clear and descriptive name to your discovery job. A recommended naming convention is, customer name underscore.03:28Discovery_May 2026, aiding in future tracking and auditing.03:48Next, select the discovery type. Catalyst Center offers CDP, IP address range, and CIDR. We suggest using the IP address range for customer engagements, as it offers precise control over which subnets are scanned, minimizing unintended device discoveries.03:55Enter the IP address range provided by the customer, ensuring it encompasses all subnets with relevant devices such as controllers, access points, and switches. Confirm this range with the customer's network team before proceeding. In the credentials section, provide a.04:14Authentication informations.04:34Minimum requirements includes CLI credentials and SNMP credentials. For modern setups, also configure NETCONF credentials for enhanced automation features. Else. Click add credentials, then enter the CLI Access username and password. Add SNMP read and write community strings.04:36Or SNMPV three credentials if applicable. Ensure these credentials align with device settings or discovery will not succeed.04:55Review advanced settings such as protocol order and SNMP polling parameters, NO. Default settings usually suffice, but verify compatibility with the customer's environment. I want.05:03As everything is configured, click discover at the bottom of the page.05:23Catalyst Center will start scanning the specified IP range using provided credentials to communicate with each active device. You'll then be redirected to the discovery progress screen where you can monitor the job in real time. The dashboard displays the number of reachable devices successfully authenticated devices, and any failures.05:27Upon completion, examine the results. Confirm the discovery of two wireless LAN controllers, five access points, and 20 network devices address any errors by checking reasons such as credentialed mismatches or unreachable IPs.05:48Once all devices are verified, proceed to the provision section, then inventory ensure that all discovered devices are listed as reachable and managed. This concludes the discovery phase. You have successfully onboarded all required devices into Catalyst Center, setting the stage for the next phase, building your network hierarchy.06:03Buying templates and enabling assurance. In our next catalyst capsule, we'll cover network hierarchy design.06:23Thank you for watching and see you in the next session. Let's summarize what we accomplished during the demo. We 1st created a discovery job and assigned it a name. Using the IP range method, we specified addresses to be scanned in. We included our CLI and SNMP credentials.06:29Catalyst Center efficiently scanned and added devices to the inventory, designating them as managed. This process forms the bedrock upon which all subsequent features. Automation, assurance and templates recollie. Before concluding, let's address common pitfalls to avoid.06:50During discovery, the primary cause of discovery failures is incorrect credentials, which often renders devices unreachable.07:10Double check SSH and SNMP credentials thoroughly. Secondly, ensure firewalls or access control lists do not block traffic, as Catalyst Center requires access via SSH, SNMP, and ICMP. Thirdly, always validate that your IP range is.07:18Comprehensive. Missing out parts of your network will lead to incomplete discovery. Following these guidelines will ensure smooth operation.07:37This concludes episode two of catalyst capsules. To recap, discovery is the foundation that enables future operations. With your network inventory established and devices managed. You'll be well prepared for the next phase. In our upcoming episode, we'll focus on constructing your network hierarchy, including sites, buildings, and floors, to reflect your actual environment.07:47Thank you for your attention, and I look forward to seeing you in the next episode.08:07
