Cisco Nexus Dashboard 4.1 (1g) Sandbox
The Nexus Dashboard Sandbox provides a self-paced environment where you can explore and experiment without guided instructions. Unlike a structured guide lab, this sandbox offers multiple isolated environments for you to practice onboarding devices, configuring vPCs, VRFs, network segmentation, and tenant connectivity entirely on your own. You can test external route advertisement, route leaking between VRFs, and the interaction of Border Gateways and Border Gateway Spines, as well as experiment with Multi-Site Domain integration. This sandbox is designed to give you hands-on freedom to explore Nexus Dashboard's centralized management, visibility, and operational capabilities, building confidence in fabric management through trial, error, and discovery.
Cisco Nexus Dashboard 4.1: VXLAN EVPN Fabric Deployment
Nexus Dashboard provides a centralized platform to simplify the deployment, management, and extension of VXLAN EVPN fabrics. In this hands-on lab, you will start by onboarding devices, then configure vPCs, VRFs, and networks to enable segmentation and tenant connectivity. You'll also implement external route advertisement, route leaking between VRFs, and explore the roles of Border Gateways versus Border Gateway Spines. Finally, you'll integrate multiple fabrics into a Multi-Site Domain, building a scalable, distributed architecture. This lab demonstrates the value of Nexus Dashboard in providing centralized visibility, streamlining operations, and simplifying complex fabric management across sites.

Cisco Nexus Dashboard 4.1 Fundamentals Lab
The Cisco NEXUS Dashboard 4.1 Fundamentals lab is a virtual environment hosted inside WWT's ATC. To access the environment, launch the lab, and the virtual application and simulated hardware will be reserved for the duration. Once the lab is reserved, credentials and remote access information will be supplied to access a jump box into the lab environment. A lab guide explores everyday NEXUS Dashboard administrative tasks, including backup, remote storage, software upgrades, and managing the platform, which are all included in the lab.
The base lab is designed to introduce students to the Nexus Dashboard, explicitly focusing on the Graphical User Interface (GUI) of the latest 4.1 release. This lab is ideal for individuals new to the Nexus Dashboard or who have not yet explored the latest features. The lab environment includes a 3-node Nexus Dashboard cluster with pre-installed NEXUS Insights (NI). The Nexus Dashboard has been prepopulated with online data, and snapshot sites are preconfigured to facilitate using NEXUS Insights in subsequent exercises. The primary goal is to provide a comprehensive overview of the Nexus Dashboard GUI, helping students become familiar with its functionalities and features.

Intent Based Networking with Juniper Apstra
This lab will enable a student to build a basic Multi-Site fabric using Apstra for complete end-to-end connectivity.
Cisco ACI Fundamentals Lab Part 1
This lab is the Cisco ACI Fundamentals Lab Part 1, and after completion, the student can launch Cisco ACI Fundamentals Lab Part 2 to complete the entire lab. The lab uses the ACI virtual simulator based on ACI Version 6.1(3f), emulating an APIC, 2 leafs, and a spine. Part 2 uses a shared physical ACI fabric to complete the policy and verify data plane connectivity.
The ACI Virtual Simulator was needed to demo the building of the ACI fabric from scratch, bootstrapping the APIC, adding the spine and leafs, fabric discovery, and completing VMM integration. Since the Cisco ACI Fundamentals Lab, Part 2 is a shared on-demand environment, to decouple the APIC build process from the APIC policy creation. Due to limitations, the virtual ACI fabric is a control plane-only simulator, and no data plane testing (Ping, SSH) can get done for validation. Cisco ACI Fundamentals Lab Part 2 uses a Tenant inside of a physical ACI, and data plane functionality can get tested ( Ping, SSH)
Cisco ACI Fundamentals Lab Part 2
This lab is a continuation of the Cisco ACI Fundamentals Lab Part 1 to allow students to explore the basics of ACI Constructs, building an Application Profile, EPGs and Bridge domains, Policy Filters, and Contracts. The students then connect the ACI fabric to external layers 2 and 3 devices. The lab then finishes with ACI micro-segmentation inside an EPG to show a zero-trust model.
Unlike Cisco ACI Fundamentals Lab Part 1, which uses a simulator due to resource sharing with other students, this lab uses the latest ACI hardware and allows the student to test real-world data plane connectivity inside and outside the fabric.
