⁠5.3. Understanding the Default Behavior of Master and Slave Interfaces

When controlling teamed port interfaces using the NetworkManager daemon, and especially when fault finding, keep the following in mind:
  1. Starting the master interface does not automatically start the port interfaces.
  2. Starting a port interface always starts the master interface.
  3. Stopping the master interface also stops the port interfaces.
  4. A master without ports can start static IP connections.
  5. A master without ports waits for ports when starting DHCP connections.
  6. A master with a DHCP connection waiting for ports completes when a port with a carrier is added.
  7. A master with a DHCP connection waiting for ports continues waiting when a port without a carrier is added.
