MultiAccess is a low latency FPGA-based Ethernet firewall or multiplexer/demultiplexer with configurable port ACLs (PACL). The MultiAccess FPGA application, which is delivered as an EOS extension in a “swix” file format includes various profiles which dictate and instantiate supported interface speeds and features. All MultiAccess profiles support MAC and IP PACLs, in either ingress, egress, or ingress and egress directions. Profiles may also perform packet multiplexing and demultiplexing, storm control, firewalling, and VLAN tunneling, all across various speeds and port layouts. MultiAccess’s port to port latency is a function of the selected MultiAccess profile, interfaces being used, interface configuration, and the platform itself. For latency details, please refer to the Latencies section of this TOI.

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. 

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.
