Provisioning is the final step in the LAN automation process. It is divided into two stages:

1. Device discovery and onboarding (starting LAN automation)

   When LAN automation starts, Catalyst Center

   1. pushes the loopback and IS-IS configuration to the primary and peer seed devices and the temporary configuration to the primary seed device, enabling discovery and onboarding of the PnP agent.

      Note

      Catalyst Center Release 2.3.3 and later support is-type level-2-only as part of IS-IS configurations.

   2. discovers new devices.

   3. upgrades the device software image and pushes the configuration to discovered devices.

      Note

      The image is updated only if a golden image is marked for that switch type in Catalyst Center under Design > Image repository.

   When LAN automation starts, the temporary configuration is pushed to the primary seed device. This allows the device to discover and onboard the PnP agent. Next, the PnP agent image is upgraded and basic configurations such as loopback address, system MTU, and IP routing are pushed to the PnP agent.

2. Interface configuration (stopping LAN automation)

   When the LAN automation process stops,

   1. the discovery phase ends, and all point-to-point links between the seed and discovered devices and between the discovered devices (maximum of two hops) are converted to Layer 3.

   2. all temporary DHCP and VLAN 1 configurations on the seed and discovered devices are removed. The DHCP subpool is returned to the LAN automation pool.
