Configuring Cellular PPP with set_cellular_ppp

The set_cellular_ppp command in the ChromeOS Shell is used to configure Point-to-Point Protocol (PPP) settings for cellular connections. This command enables advanced control over how ChromeOS devices establish and maintain cellular network connections.

Usage

bash set_cellular_ppp <option> [<value>]

Parameters

  • <option>: The specific PPP setting to configure. Common options include:
  • enable: Enable PPP mode for cellular connections.
  • disable: Disable PPP mode for cellular connections.

  • status: Check the current PPP configuration.

  • <value> (optional): The value to apply for the given option. Not all options require a value.

Examples

1. Enable PPP Mode

bash set_cellular_ppp enable

This command enables PPP mode for cellular connections, allowing data transmission using the protocol.

2. Disable PPP Mode

bash set_cellular_ppp disable

This command disables PPP mode, reverting to default settings for cellular connections.

3. Check Current PPP Status

bash set_cellular_ppp status

This displays the current PPP settings, providing details about whether PPP mode is enabled or disabled.

Additional Information

  • Purpose: PPP settings are critical for specific cellular configurations, often required for legacy or specialized network setups.
  • Device Compatibility: This command may not be available on all ChromeOS devices or may require developer mode.
  • Impact: Changes to PPP settings can affect cellular connectivity and should be applied cautiously.

Best Practices

  1. Verify Requirements

  2. Confirm with your network provider whether PPP mode is necessary for your connection.

  3. Test After Configuration

  4. Use tools like ping or arc http to verify network connectivity after applying PPP changes.

  5. Document Changes

  6. Maintain a record of PPP configurations for troubleshooting or reverting settings if needed.

The set_cellular_ppp command provides fine-grained control over cellular connections, making it a valuable tool for users with advanced networking requirements.
