Dual Trunk E1 Router
CLI Command Modes
The commands available are divided in three categores (Unit, Kernel, and Routing) and arranged in
a hierarchy. Each of the three modes has its own set of commands and its own sub modes of
hierarchy.
The commands available for each routing protocol (RIP and OSPF) are separated into several
modes and arranged in a hierarchy. Enable is the default mode and is the lowest level. Each mode
has its own special commands; in some modes, commands from a lower level are available..
When you enter the CLI, the following prompt is displayed:
Access Router CLI, type
Unit to enter Unit mode
Kernel to enter kernel mode
Rip to enter RIP mode
Ospf to enter OSPF mode
Quit to exit

optional. Each one of which is replaced by more keywords and values.
