    Switchport Mode Configuration Preserved: When switching between switchport modes (access, trunk, and general), the switchport configuration applicable to the selected mode is maintained. This means that when switching from one mode to another and back, the port will have the same configuration as it had in the original mode. Only the configuration applicable to the selected mode is active on the port.
