6 Steps to Understanding Cisco ACI
When understood, these six concepts will help anyone new to ACI to understand a more detailed technical discussion.
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, 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)
Understanding Data Center Quantized Congestion Notification (DCQCN)
RoCEv2 is a solution for achieving swift data throughput and minimal delay in modern data centers. It incorporates features like Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) to establish a lossless network environment. PFC manages data flow at the interface level, while ECN detects and mitigates congestion before PFC activation becomes necessary. The combination of ECN and PFC, known as Data Center Quantized Congestion Notification (DCQCN), optimizes congestion management in RDMA networks. Careful tuning of queue thresholds is crucial to prevent hot spots and ensure low Job Completion Times (JCTs). The use of ECN and PFC is necessary for maintaining a lossless fabric in GPU-to-GPU communication during AI/ML training runs.

Cisco ACI Fundamentals Lab Walkthrough: Part 1
This playlist is recommended to be used in conjunction with part 1 of our Cisco ACI Fundamentals Lab using the Cisco ACI APIC simulator. These videos will show the students how to perform the labs in detail and answer any other questions not covered in the lab itself. The videos will cover: a tutorial on VXLAN 101 and ACI 101 basics, initial configuration of the APIC 5.0 controller via APIC console using the APIC simulator, APIC 5.0 switch Fabric Discovery via the registration process, APIC 5.0 GUI discovery, and Virtual Machine Manager (VMM) Networking. The Cisco ACI Part 2 Lab and playlist completes the learning by covering how to use a physical ACI fabric with a data plane for testing connectivity. Please be aware that the videos are based on ACI 5.x, and the lab is 6.1, so there will be some GUI differences. The content and configurations are the same and we will be updating the videos once we do a major upgrade to the labs.

Cisco Networking: Layer 2 Technologies
This Learning Series covers several key network engineering concepts, including VLANs and Trunks, EtherChannels, and Spanning Tree Protocol (STP). Through practical labs and real-world scenarios, you'll gain hands-on experience in configuring and managing resilient networks. The journey begins with VLANs and trunking, where you'll learn about network segmentation. Next, you'll explore EtherChannels to enhance link aggregation and redundancy. Finally, you'll master Spanning Tree Protocol to prevent network loops and optimize performance. Ideal for aspiring network engineers, IT professionals, or anyone looking to expand their knowledge of contemporary network infrastructure.

Operating the Cisco NEXUS Dashboard Platform
Cisco has been at the forefront of developing a suite of standalone tools for data center networking, collectively known as the Day 2 Operations Suite. Recently, Cisco has initiated the integration of these tools into a unified interface called NEXUS Dashboard, providing a consolidated view and shared data repositories for enhanced application correlation. This Learning path is designed specifically for those administrators that need to perform and manage the day to day upkeep of the NEXUS Dashboard product. The learning path will include videos, article and a hands on lab going over what a typical admin would need to setup on NEXUS Dashboard. We will cover whats new with NEXUS Dashboard 3.2, creating routes for the management and data networks, creating syslog server, remote NFS and SFTP storage, creating backups, and upgrading the version. We will also go through remote authentication with radius, creating users and roles, and Intersight configuration. Finally we will bring up 2 ACI simulators and onboard the ACI fabrics to the NEXUS Dashboard platform.

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.
Arista With Cloud Vision Portal Sandbox Lab
This lab provides exposure to the new technology and capabilities of the Arista products used. This lab introduces the Arista Cloud Vision Portal(CVP) and includes 3 VXLAN EVPN scenarios based on best practices from the Arista design guides, ACE3 course material and Arista TAC support the Arista EOS forum posts. There are many different ways to create an Arista-based VXLAN EVPN fabric; these 3 lab scenarios presents 1) a migration phase from a standard 3 tier VLAN and SVI-based network to a VXLAN fabric, 2) using Asymmetrical IRB and 3)Symmetrical IRB. BGP routing is the underlay, overlay, and connectivity to the remote data center under migration. This sandbox and configs can be further used to explore other configurations and functionality of Arista CVP.
