no switchport
Use the
no switchport
command (without parameters) to set the interface to the routed-interface status
and to erase all Layer 2 configurations. You must use this command before assigning an IP address to a
routed port.

If an interface is configured as a Layer 3 interface, you must first enter this
switchport
command with
no keywords to configure the interface as a Layer 2 port. Then you can enter additional switchport
commands with keywords, as shown on the pages that follow.

Usage Guidelines
Entering the
no switchport
command shuts the port down and then re-enables it, which might generate
messages on the device to which the port is connected.
Examples

Cisco-routed port:
Switch(config-if)#
no switchport
This example shows how to cause the port interface to cease operating as a Cisco-routed port and convert
to a Layer 2-switched interface:
