CLI Basics
The OS10 CLI is the software interface you use to access a device running the software — from the console or through a
network connection. The CLI is an OS10-specific command shell that runs on top of a Linux-based OS kernel. By leveraging
industry-standard tools and utilities, the CLI provides a powerful set of commands that you can use to monitor and configure
devices running OS10.
User accounts
OS10 defines two categories of user accounts:
● To log in to the CLI, use admin for the user name and password.
● To log in to the Linux shell, use linuxadmin for the user name and password.
NOTE: You cannot delete the default linuxadmin user name. You can delete the default admin user name only if at least
one OS10 user with the sysadmin role is configured.
For example, to access the OS10 CLI using an SSH connection:
1. Open an SSH session using the IP address of the device. You can also use PuTTY or a similar tool to access the device
remotely.
ssh admin@ip-address
password: admin
2. Enter admin for both the default user name and password to log into OS10. You are automatically placed in EXEC mode.

For example, to access the Linux shell using an SSH connection, enter linuxadmin as the user name and password:
ssh linuxadmin@management-ip-address
password: linuxadmin
Key CLI features
Consistent
command names
Commands that provide the same type of function have the same name, regardless of the portion of the
system on which they are operating. For example, all show commands display software information and
statistics, and all clear commands erase various types of system information.
Available
commands
Information about available commands is provided at each level of the CLI command hierarchy. You can
enter a question mark (?) at any level and view a list of the available commands, along with a short
description of each command.
Command
completion
Command completion for command names (keywords) and for command options is available at each level
of the hierarchy. To complete a command or option that you have partially entered, click the Tab key or
the Spacebar. If the partially entered letters are a string that uniquely identifies a command, the
complete command name appears. A beep indicates that you have entered an ambiguous command, and
the possible completions display. Completion also applies to other strings, such as interface names and
configuration statements.
CLI command modes
The OS10 CLI has two top-level modes:
● EXEC mode — Monitor, troubleshoot, check status, and network connectivity.
● CONFIGURATION mode — Configure network devices.
When you enter CONFIGURATION mode, you are changing the current operating configuration, called the running configuration.
By default, all configuration changes are automatically saved to the running configuration.
You can change this default behavior by switching to Transaction-Based Configuration mode. To switch to Transaction-Based
Configuration mode, use the start transaction command. When you switch to the Transaction-Based Configuration mode
and update the candidate configuration, changes to the candidate configuration are not added to the running configuration until
