Dell C1048P Port Extender Networking Configuration Guide for the C9000 Series - Page 37

2 Configuration Fundamentals The Dell Networking OS command line interface (CLI) is a text-based interface you can use to configure interfaces and protocols. The CLI is structured in modes for security and management purposes. Different 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 configuration file. You can view the current configuration for the whole system or for a particular CLI mode. To save the current configuration, copy the running configuration to another location. NOTE: Due to differences in hardware architecture and continued system development, features may occasionally differ between the platforms. Differences are noted in each CLI description and related documentation. In Dell Networking OS, after a command is enabled, it is entered into the running configuration file. You can view the current configuration for the whole system or for a particular CLI mode. To save the current configuration copy the running configuration to another location. Accessing the Command Line Access the CLI through a serial console port or remote session. When the system successfully boots, enter the command line in EXEC mode. NOTE: You must have a password configured on a virtual terminal line before you can Telnet into the system. Therefore, you must use a console connection when connecting to the system for the first time. Dell> telnet 172.31.1.53 Trying 172.31.1.53... Connected to 172.31.1.53. Escape character is '^]'.
