Changing the MTU on the management network

Before you begin

Ensure that you have the MTU value for the management network.


  1. Connect to e1n1 by using the management floating IP.
  2. Update the MTU value in the network entries by following Shared management network variables.
  3. Validate the YAML file.
  4. Test the YAML file and run the playbooks.
  5. Validate that all nodes are accessible through their management IP addresses ( nodes 1-3 and the floating_ip).
