CLI Contexts
Use the CLI to access, configure, and manage Alcatel-Lucent’s SR OS routers. CLI commands are
entered at the command line prompt. Access to specific CLI commands is controlled by the
permissions set by your system administrator. Entering a CLI command makes navigation possible
from one command context (or level) to another.
When you initially enter a CLI session, you are in the ROOT context. Navigate to another level by
entering the name of successively lower contexts. For example, enter either the
configure or show
commands at the ROOT context to navigate to the config or show context, respectively. For
example, at the command prompt (#), enter config . The active context displays in the command
prompt.
A:ALA-12# config
A:ALA-12>config#
In a given CLI context, enter commands at that context level by simply entering the text. It is also
possible to include a command in a lower context as long as the command is formatted in the
proper command and parameter syntax.
The following example shows two methods to navigate to a service SDP ingress level:
Method 1:
A:ALA-12# configure service epipe 6 spoke-sdp 2:6 ingress
*A:ALA-12>config>service>epipe>spoke-sdp>ingress#
Method 2:
A:ALA-12>config# service
A:ALA-12>config>service# epipe 6
*A:ALA-12>config>service>epipe# spoke-sdp 2:6
*A:ALA-12>config>service>epipe>spoke-sdp# ingress
*A:ALA-12>config>service>epipe>spoke-sdp>ingress#
The CLI returns an error message when the syntax is incorrect.
*A:ALA-12>config# rooter
Error: Bad command.
