The document captures the default preference value (between and 255) for routes from various supported protocols.

We now support configuration diffs to be generated and to be streamed via OpenConfig.  Please note that there are limitations to using this feature to obtain the correct configuration diff of consecutive configuration changes.  Subsequent sections will explain:

Like SWL switches, EOS switches now report their SKUs to the DANZ Monitoring Fabric (DMF) Controller. View the EOS switch SKU using the DMF Controller CLI or GUI.

Before this feature was introduced, any daemon agent needing to interface with Sysdb for configuration retrieval and status updates had to go through the agent manager within the EOS SDK. Usage of the EOS SDK introduced various ABI issues due to constraints on which compiler, libc and kernel versions the daemon must be built with. This feature offers an alternative mechanism via gRPC, providing more flexibility in how daemon executables are built and used to programmatically interact with and monitor the EOS device.

This feature introduces the ability to mirror the SSH/HTTPS cryptographic configuration of the DMF controller to the managed appliances (i.e., service nodes and recorder nodes) and the SSH cryptographic configuration of the controller to the EOS switches.

Use this feature to configure Access Control Lists (ACLs) on a managed device that do not directly reflect the ACLs configured on the controller. Specifically, a user can override the user-configured ACLs on the controller (generally inherited by the managed devices) so that ACLs allowing specific types of traffic from the controller-only are pushed to managed devices.

This supports checking that the value of a given x509 certificate OID matches a user-provided value during the TLS handshake in OpenConfig. If the value does not match, no connection will be established.

The system reinstall feature allows users to reinstall EOS on an Arista switch. A system reinstall is accomplished by removing the local startup-config/zerotouch-config on the switch so the DMF controller no longer manages it. Rebooting the switch restarts the Arista native ZTP process and requests a fresh image from the controller.
