"switchport port-security" command not avaliable

[DVSfour20]

Im tyring to follow along documentation i see via train single videos and some online resources. I am trying to enable port security.

I have a Catalyst 3546 XL

when i type in "rtr1# switchport ?"

"port-security" is not only of the options to choose from.   I have already set this as an access port.

Any help would be great! If you need more information, please let me know

THanks,

Adam

Are you in configuration mode?
