Fabric-based Firmware Download Preparation
The firmware download prepare add and delete command accept a new --fabric <fabric name> parameter. This parameter automatically generates a group-based prepared list for the entire fabric or delete any existing prepared list for the entire fabric.
You can review and further modify the auto-generated prepared list using the group-based prepare commands if required.
Clos Topology (3-Stage and 5-Stage)
The following rules for Clos topologies generate a fabric-based prepared list:
- The first group contains all non-MCT leaf devices and the MCT peer with the lower IP address from all MCT leaf and border-leaf devices.
- The second group contains the MCT peer with the higher IP address from all MCT leaf and border-leaf devices.
- The subsequent groups contains a single spine per group starting from the lowest to highest IP address of the spines.
The remaining groups contain a single super-spine per group starting from the lowest to highest IP address of the super-spines.
Small Data Center Topology (Centralized Rack and Rack Ring)
The following rules for small data center topologies generate a fabric-based prepared list:
- Due to potential loss of connectivity between racks (rack ring topology), all the devices are prepared for a serial upgrade (one device per group).
- The order is rack-by-rack, with the lower IP address peer followed by the higher IP address peer.
