Symptoms

 

A WD19 dock on my new Latitude 5300 2-in-1 or 5400 Chromebook does not change the MAC address when you change the MAC Pass-through policy

(Figure.1 WD19/WD19S Type-C Connected Dock)

The MAC address on the WD19/WD19S dock that is connected to your Latitude 5300 2-in-1 or 5400 Chromebook laptop does not automatically change. It happens when you change the MAC Address Pass-Through policy in Device Setting in the Chrome OS.

Disconnecting the laptop from the dock and redocking it allows the policy changes to take effect on the dock.

You need to use the ifconfig command to check the docks MAC address (eth0, eth1, so on) after making policy changes.

Note: The dock's MAC address does not change until the laptop is reconnected to the dock. You have to check the dock's MAC address to notice this issue. You can still access the Internet using the docks Wired Local Area Network (LAN) connection. For more information about running the ifconfig command in the Chrome OS you should see the following knowledge article:
