Conguration Fundamentals
The Dell Networking OS command line interface (CLI) is a text-based interface you can use to congure interfaces and protocols. The CLI
is structured in modes for security and management purposes. Dierent sets of commands are available in each mode, and you can limit
user access to modes using privilege levels.
After you enter a command, the command is added to the running conguration le. You can view the current conguration for the whole
system or for a particular CLI mode. To save the current conguration, copy the running conguration to another location.
NOTE: Due to dierences in hardware architecture and continued system development, features may occasionally dier between
the platforms. Dierences are noted in each CLI description and related documentation.
In Dell Networking OS, after a command is enabled, it is entered into the running conguration le. You can view the current conguration
for the whole system or for a particular CLI mode. To save the current conguration copy the running conguration to another location.
