Overview

This is the Command Line Interface (CLI) reference guide for Island Router firmware version 2.3.2.

The Command Line Interface (CLI) provides a low-level interface for the configuration and monitoring of the Island router. It is accessed via the SSH protocol on TCP port 22. On some Island models, the CLI can also be accessed through a serial port.

When logging in to the CLI, two different user names are available: “admin” and “user”. The admin account has full privileges and access to all CLI commands. The user account is a read-only account which cannot access any commands that change the system configuration.

Before the CLI can be accessed, the SSH password must be set via the Island app. This sets the password for the “admin” user. The password for the “user” login can be set by the admin user using the CLI password command.

The CLI can also be accessed using SSH public key authentication. Authorized keys can be configured using the configure authorized-keys CLI command.

CLI command names and most keywords cay be abbreviated using the shortest unique prefix. For example, show interface summary can be abbreviated as sh int sum or even sh in su, but not as s int sum since the leading "s" is ambiguous.

Most CLI commands take effect immediately when issued, but are not saved to non-volatile storage until the write memory command is issued. In other words, the write memory command makes the current running configuration permanent by copying it to the startup configuration. Note, however, that any configuration changes made through the app cause the running configuration to be immediately saved to non-volatile storage, including any changes made using the CLI.
