Purpose
Enters global configuration mode.
Specifies the port to be configured, and enter interface
configuration mode.
Use the replace keyword to enable MAC replace on the interface.
The port removes the current session and initiates authentication
with the new host.
The other keywords have these effects:
• protect: the port drops packets with unexpected MAC
addresses without generating a system message.
• restrict: violating packets are dropped by the CPU and a
system message is generated.
• shutdown: the port is error disabled when it receives an
unexpected MAC address.
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
