If you experience trouble with configuration settings in heterogeneous stacks, please note:
Because stacks can consist of switches of different series and different models, ExtremeXOS does not restrict configuration settings based on the capabilities of any particular node in the stack. Therefore, you are responsible for ensuring that your configuration settings are appropriate for all switches in the stack.
(This text will be added to the Stacking chapter in the next edition of the EXOS User Guide.)
