Thanks for sharing your feedback!
This article provides a directory of all base CLI commands supported by Skylight Flex. They are intended to be a reference for users and system administrators who will configure Skylight Flex through the CLI interface.
The scope of these articles is limited to Skylight Flex release 21.09 or above. They detail all the Base CLI commands provided by the Skylight Flex software. Commands that are not applicable for a specific hardware platform are indicated wherever necessary.
Conventions
CLI command descriptions and procedures:
Command and argument keywords are displayed in bold:

gps edit state { enable | disable }Arguments that must be replaced with a value are in angle brackets < > or italics:
dns edit hostname < hostname >
dns edit hostname hostnameOptional arguments are enclosed in square brackets [ ]:

Command executed successfully
The CLI (Command Line Interface) is used to configure Skylight Flex from a console attached to the serial port of the switch or from a remote terminal using SSH or Telnet (see Enabling Telnet).
Notes:
The maximum number of CLI users that can be defined on a Skylight Flex 100 device is 15.
The maximum number of simultaneous SSH/Telnet sessions is 8.
A new user can be created or an existing user can be deleted, and one's own password or password of the other users can only be modified, if logged in as a root user.
Usernames do not support special characters (only A to Z, a to z, 0 to 9 ).
Supported characters for passwords are: ~ ` @ # $ % ^ & * ( ) - _ = + [ ] { } : ‘ , . < > /
Supported characters for hostnames are: ~ # % ^ * - _ = + . [ ] { }
In SFTP configurations, the backslash (\) is also supported in the password field (but not the hostname field) for SFTP command operation.
The following table lists the generic CLI command modes.
Command Line Interface Parameters
| Command Mode | Access Method | Prompt | Exit Method |
|---|---|---|---|
| User EXEC | This is the initial mode to start a session. | Your Product> | The logout method is used. |
| Privileged EXEC | The User EXEC mode command enable is used to enter the Privileged EXEC mode. | Your Product# | To return from the Privileged EXEC mode to User EXEC mode, the disable command is used. |
| Global Configuration | The Privileged EXEC mode command configure terminal is used to enter the Global Configuration mode. | Your Product(config)# | To exit to the Privileged EXEC mode, the end command is used. |
| Interface Configuration | The Global Configuration mode command interface < interface-type >< interface-id > is used to enter the Interface configuration mode. | Your Product(config-if)# | To exit to the Global Configuration mode, the exit command is used and to exit to the Privileged EXEC mode, the end command is used. |
| Config-VLAN | The Global configuration mode command vlan vlan-id is used to enter the Config-VLAN mode. | Your Product(config-vlan)# | To exit to the Global Configuration mode, the exit command is used and to exit to the Privileged EXEC mode, the end command is used. |
Note: To login into the User Exec mode, enter your username (default is root) and password (default is admin123). To login to the Privileged mode, use the enable command or login with admin username and password.
Configuring the Skylight Flex using the Command Line Interface.
The Command Line Interface (CLI) can be used to configure Skylight Flex from a console attached to the serial port of the switch or from a remote terminal using SSH, after an IP address is configured (see Installation Procedure for Accedian Board).
The Skylight Flex CLI supports a simple login authentication mechanism. The authentication is based on a user name and password provided by the user during login. The user "root" is created by default with password "admin123".
When Skylight Flex is started, the user name and password have to be given at the login prompt to access the CLI shell:
Login: root
Password: ********
Your Product>
The user-exec mode is now available to the user. CLI command modes provide a detailed description of the various modes available for Skylight Flex.
The command prompt always displays the current mode.
CLI commands need not be fully typed. The abbreviated forms of CLI commands are also accepted by the Skylight Flex CLI. For Example, commands like "show ip global config" can be typed as "sh ip gl co".
CLI commands are case insensitive.
CLI commands will be successful only if the dependencies are satisfied for a particular command that is issued. The general dependency is that the module specific commands are available only when the respective module is ‘enabled’. Appropriate error messages will be displayed, if the dependencies are not satisfied.
Note: The Ethernet type of an interface is determined during System Startup. While configuring interface-specific parameters, its Ethernet type needs to be specified correctly. A fastethernet interface cannot be configured as a gigabit-ethernet interface and vice-versa.
Context Sensitive Help
Skylight Flex CLI framework offers context sensitive help; The user can type a question mark (?) anytime during a session to get help. The help can be invoked in several ways. It is not displayed as a whole and is available only for the specific token from where it is invoked.
- Examples of possible scenarios are given below.
User keys in a character followed immediately by a question mark (?). This displays the current possible tokens without a help string.
Your Product(config)# bo?
bootfile
User enters a keyword at the command prompt and enters a question mark (?) after hitting a space. This displays the next possible tokens along with the corresponding help string.
Your Product(config)# service ?
dhcp DHCP related configuration
dhcp-relay DHCP relay related configuration
dhcp-server DHCP server related configuration
timestamps Timestamp configuration for logged messages
Some of the basic concepts implemented for the context sensitive help are:
The next possible tokens are listed only in the lexical order and not in the order as available in the syntax or command structure.
All possible tokens are listed along with the help string, even though the command is ambiguous. Any ambiguous command errors and value range errors are taken care only during the execution of the command.
The help tokens provided within <> brackets denote that the user should input values of specified format. For Example,
The help tokens provided within () brackets denote that the user should input only the values represented. For Example, (1-4094) represents that the user should input value within the mentioned range alone.
The format is directly provided as a help token for some non-keyword such as IP address, IP mask, MAC address and so on. For Example, aa:aa:aa:aa:aa:aa represents that a MAC address of this format should be provided.
Only the most commonly used format is provided as a help token for some non-keywords such as IPv6 address. But the command supports most of the valid formats. For Example, AAAA::BBBB represents the IPv6 address, but the command will accept the format AAAA:B::BBBB.
The help token
along with a help string explaining the operation of the command is displayed, if the command can be executed at that point (errors are handled only during the execution).
CLI Command Modes
The following table format lists the different CLI command modes. Depending on the CLI mode, your product prompt will be specific. This cannot be changed by the end user.
