Overview

This section provides procedures for initializing the ACI fabric and discovering switches through the Application Policy Infrastructure Controller. It enables users to configure multi-tier topologies, automate software conversions using POAP, and securely erase hardware data during decommissioning.

Fabric initialization

This topic explains how to initialize the fabric by adding switches to be managed by the APIC and validating the steps using the GUI, CLI, or API, after creating an APIC cluster over the out-of-band network.

Multi-tier fabric topologies example

This topic explains the multi-tier fabric topology in data center networks, highlighting its three-tier structure that enhances connectivity and port usage, and detailing the configuration requirements for Cisco Nexus 9000 Series switches to support this architecture.

Change the external routable subnet

Learn how to modify the external routable subnet configuration in your network by following a step-by-step procedure to deactivate, delete, and reconfigure subnets using the Fabric Setup Policy panel, ensuring accurate IP address allocation and verification through APIC and spine switch CLI commands.

Switch discovery with the APIC

This topic explains the process of switch discovery in a fabric management system, detailing how the APIC automatically detects and registers switches to manage the ACI fabric efficiently, ensuring each switch is managed by a single APIC cluster.

Cisco NX-OS to Cisco ACI POAP auto-conversion

This topic explains the Cisco NX-OS to Cisco Application Centric Infrastructure (ACI) power-on auto-provisioning (POAP) auto-conversion feature, which automates software upgrades and configuration installations for newly deployed network nodes.

Cisco Nexus 9000 switch secure erase

This topic explains the secure erase feature for Cisco Nexus 9000 switches, detailing how it removes user data from various storage devices during RMA, upgrades, replacements, or decommissioning, supported by Cisco APIC release 6.0(1) and later.
