Switches have a CAM (contents addresses memory ) table for MAC address filtering .

Modular switches :Allows you to add expansion modules into the switches as needed so that they provide flexibilty to changing network capabillties.
example: cisco catalyst 4000 and 6000 series switches
.
Fixed configurations:Have fixed no of ports , you can not allow to add modules .
example: cisco catalyst 2000 and 3000 series switches
