The only function of a switch is to learn the MAC addresses and interfaces to put into its address table. With a full and accurate MAC address table, the switch can make accurate forwarding and filtering decisions.
T/F |
False |
|
|
Switches build the address table bylistening to outgoing frames and examining the source MAC address in theframe. If a frame enters the switch and the source MAC address is not in theMAC address table, the switch creates an entry in the table. That table entrylists the interface from which the frame arrived. Switch learning logic is thatsimple. T/F |
True |

But if you want to use VLANs—and most every enterprise network does—you need to add some configuration. T/F |
True |
