CLI extension allows for custom CLIs commands/modes to be defined in EOS. It also integrates with EOS SDK to be able to control a daemon’s configuration and read a daemon’s status from the CLI command handlers. This feature is intended to have more customization compared to the “daemon cli” feature, which only allows for key/value pairs as cli commands, and doesn’t allow for custom CLI commands. It does this by using a statically defined YAML file that contains the daemon definition (EOS SDK or not), CLI mode, and CLI commands, very much akin to what is provided by the via configuration in the daemon cli mode.

Common Management Interface Specification (CMIS) defines, starting with revision 4.0, a standard mechanism for managing the firmware of compliant transceivers. This mechanism allows for transceivers’ firmware to be updated without having to remove the transceiver from the switch. Firmware updates may be necessary in a testing or production environment to resolve potential firmware bugs. Some transceivers may also support firmware management operations in a hitless manner (without impacting traffic).

This mechanism allows a session to lock the configuration of the switch to prevent any other session from altering the

By default when a configuration session is committed everything modified in the configuration session will be committed to the running configuration, even if the running-configuration has also changed since the configuration session was created. This means that if the running-config has been modified since the start of the configuration session then those modifications could be overridden when the configuration session is committed. 

Text running-config commands can be converted into a snapshot (JSON snapshot). A new keyword is added to the ‘copy running-config snapshot://sample’ command: the ‘transaction’ CLI keyword can be used to perform the conversion, which can also be used to create a snapshot with specific commands included.

EosSdkRpc is an agent built on top of the Arista EOS SDK. It uses gRPC as a mechanism to provide remote access to the EOS SDK. The gRPC interface that EosSdkRpc supports closely matches the interface provided by EOS SDK, and the intent is that the .proto interface can be publically supported. EosSdkRpc allows for remote access and using protobuf to specify the interface isolates user code from the Linux ABI issues that come with building C++ applications on different compiler, libc, and kernel versions. EosSdkRpc is built using C++ but supports clients written in any of the languages currently supported by the gRPC framework.

A new configuration model for the BFD (Bidirectional Forwarding Detection) agent was added in order to more
