# show running-config

## Syntax

{% code overflow="wrap" %}

```
show running-config [differences]
```

{% endcode %}

## Syntax Description

<table><thead><tr><th width="220"></th><th></th></tr></thead><tbody><tr><td><code>differences</code></td><td>(Optional) Displays a side-by-side comparison of the running and startup configurations.</td></tr></tbody></table>

## Defaults

## Usage Guidelines

This command displays the active Island configuration.

The differences option will display a side-by-side comparison of the running configuration on the left and the startup configuration on the right.

Note that any changes made to the running configuration will be lost on reload or power off unless the [write memory](/island-router-cli-2.3.2/commands/write/write-memory.md) command is used. Changes made through the Island app will also save the running configuration to the startup configuration.

## Examples

```
show running-config
```
