Outlines the firmware management process for Application Centric Infrastructure fabrics, including upgrade workflows, guidelines for different scenarios, and scheduling considerations.
Firmware management
This topic explains the different types of firmware used in Cisco ACI, including APIC firmware, switch firmware, SMU patches, and Silent Role packages, and provides examples and descriptions for each type.
Upgrade or downgrade Cisco ACI fabrics
This process describes the steps to upgrade or downgrade the Cisco ACI fabric, including actors, prerequisites, and workflow stages for a successful operation.
Guidelines for ACI switch upgrades and downgrades
Outlines the essential principles for upgrading and downgrading ACI leaf and spine switches. It provides critical rules for maintaining network availability, including strategies for logical switch grouping, managing concurrent upgrade capacity, optimizing image deployment through pre-downloading, and executing graceful upgrades to ensure minimal traffic disruption.
How multistep upgrades and downgrades work
Describes the process for upgrading or downgrading Cisco ACI fabric components through multiple intermediate software releases when a direct path is not supported.
Huge fabric upgrades and downgrades
Describes the process of upgrading or downgrading huge fabrics with large numbers of switches across multiple maintenance groups.
Guidelines for App Center Apps
Outlines requirements for managing App Center apps during Cisco APIC software upgrades and downgrades.
Determine current software version
Determine the software version that is currently running on the switches and APICs in your fabric.
Upgrade or downgrade with the scheduler
Describes how the scheduler enables you to specify a window of time for operations such as upgrading or downgrading Cisco APIC clusters and switches.
