CLI Structure
The SR OS CLI is a command-driven interface accessible through the console, Telnet and
secure shell (SSH). The CLI can be used for configuration and management of routers.
The SR OS CLI command tree is a hierarchical inverted tree. At the highest level is the ROOT
level. Below this level are other tree levels with the major command groups; for example,
configuration commands and show commands are levels below ROOT.
