At a IOS component you sometimes want a sequentially ordered interfaces in a cisco 3700 stack. A switch in a stack can not be un-provisioned or re-provisioned, so removing and adding a physical switch in a running Stack does not work. It generates following syslog message:

%Switch can not be un-provisioned when it is physically present

To change a index number of a physical component in a stack use following IOS command:

switch(config)#switch 3 renumber 1
