Could you advise why I do not see that command?

Hi,

This command is supported on models with built-in switch (like 5505) but not on higher end models.

From cisco Docs:

For models with a built-in switch, such as the ASA 5505 adaptive security appliance, use the switchport monitor command in interface configuration mode to enable SPAN, also known as switch port monitoring.
