Concept Guide

Accessing the Instant CLI
Instant supports the use of Command Line Interface (CLI) for scripting purposes. When you make
configuration changes on a master W-IAP in the CLI, all associated W-IAPs in the cluster inherit these changes
and subsequently update their configurations. By default, you can access the CLI from the serial port or from
an SSH session. You must explicitly enable Telnet access on the W-IAP to access the CLI through a Telnet
session.
For information on enabling SSH and Telnet access to the W-IAP CLI, see Configuring Terminal Access on page
83.
Connecting to a CLI Session
On connecting to a CLI session, the system displays its host name followed by the login prompt. Use the
administrator credentials to start a CLI session. For example:
(Instant AP)
User: admin
If the login is successful, the privileged command mode is enabled and a command prompt is displayed. For
example:
(Instant AP)#
The privileged mode provides access to show, clear, ping, traceroute, and commit commands. The
configuration commands are available in config mode. To move from privileged mode to the configuration
mode, enter the following command at the command prompt:
(Instant AP)# configure terminal
The configure terminal command allows you to enter the basic configuration mode and the command prompt
is displayed as follows:
(Instant AP)(config)#
The Instant CLI allows CLI scripting in several other sub-command modes to allow the users to configure
individual interfaces, SSIDs, access rules, and security settings.
You can use the question mark (?) to view the commands available in a privileged mode, configuration mode, or
sub-mode.
Although automatic completion is supported for some commands such as configure terminal, the
complete exit and end commands must be entered at command prompt.
Applying Configuration Changes
Each command processed by the Virtual Controller is applied on all the slaves in a cluster. The changes
configured in a CLI session are saved in the CLI context. The CLI does not support the configuration data
exceeding the 4K buffer size in a CLI session. Therefore, it is recommended that you configure fewer changes at
a time and apply the changes at regular intervals.
To apply and save the configuration changes at regular intervals, use the following command in the privileged
mode:
(Instant AP)# commit apply
To apply the configuration changes to the cluster without saving the configuration, use the following command
in the privileged mode:
(Instant AP)# commit apply no-save
To view the changes that are yet to be applied, use the following command in the privileged mode:
(Instant AP)# show uncommitted-config
