1. A method for managing a port of a network device, the method comprising:
determining the value of a Port-Limited flag associated with the port;
when the port's current state is either Enabled or Operational, determining, based at least in part on the value of the Port-Limited flag, whether to transition the port from its current state to a Limited state;
when the port's current state is Limited, determining, based on the value of the Port-Limited flag, whether to transition the port from the Limited state to the Operational state;
prior to determining the value of the Port-Limited flag, setting the value of the Port-Limited flag to TRUE;
after setting the value of the Port-Limited flag to TRUE, obtaining configuration parameters for the port; and
as a result of obtaining the configuration parameters for the port, setting the value of the Port-Limited flag to FALSE.
