CLI Contexts
Use the CLI to access, configure, and manage Alcatel-Lucent’s 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
