Command History
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.
When you put an interface that is in Layer 2 mode into Layer 3 mode (or the reverse), the previous
configuration information related to the affected interface might be lost, and the interface is returned to
its default configuration.
Note
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.
Examples
