CLI Structure
Alcatel-Lucent’s SR-Series Operating System (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 7750 SR-Series routers.
The 7750 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.
The CLI is organized so related commands with the same scope are at the same level or in the
same context. Sublevels or subcontexts have related commands with a more refined scope.
Figure 1 and Figure 2 display the major contexts for router configuration.
