Hi, starting with R80, SmartConsole is your one app for everything. One single pane of glass for configuration, logs, multi-domain management, events, command-line, and device operations.
During login, typing an IP of a Multi-Domain Server and pressing "Login" will present an additional step that asks you to choose which domain would you like to connect to.
You can also type an IP of a Multi-Domain server followed by \Domain-Name and it will skip the "choose domain" step and will just login to your desired domain (for example, if my domain name is LondonDomain and my Management IP is 192.168.12.1 I can just type 192.168.12.1\LondonDomain under Server IP).
