WAVE Server: How to fix ethernet settings reverting to DHCP after reboot

  • Updated

Applies to:  Linux WAVE Server

Issue Summary:

Customers setting their Ethernet interfaces to static on WRR-P-E201L models may find that the settings revert to DHCP after a reboot. This issue can disrupt network configurations and requires attention to ensure that static settings persist. This article provides instructions for configuring static Ethernet settings to prevent them from reverting to DHCP after a reboot.

Resolution:

Download the attached script to any folder, e.g. /home/wave/Downloads

Select the Terminal (mceclip0.png ) icon and enter the following command (this is CASE Sensitive):

$ sudo python3 /home/wave/Downloads/updateYAML-20241029.py

NOTE: There is no input parameter. The default YAML file location is 
/etc/net/plan/00-installer-config.yaml
SuperUser execution is required.

A copy of 00-installer-config.yaml will be made to 00-installer-config.yaml.tmp and the script will execute the following command after the YAML file is updated successfully.

sudo netplan apply

NOTE: The error output can be any of the following:
- /etc/netplan/00-installer-config.yaml file not found
- Script execution error
- Netplan command failed
- Script is not running using sudo

Once the execution is successful, you will see the following:
00-installer-config.yaml updated successfully
