 What does a switch do? switch Keeps track of What hardware devices are connected to it? Along what ports by? Recording the MAC addresses of those devices if the MAC address of a device is not found it usually Floods the packet to all the devices connected to it now Let us see What? Devices are connected to this switch by giving the command show MAC address table Now we can see that there are one two three four five Interfaces one two three four five and then we can also see the corresponding MAC addresses of the those devices which are connected on On those ports for example on the port fast Ethernet 0 slash 1 3 Router is connected and the MAC address of that router is this 0060 to F2 e e 9 0 1 Similarly for other interfaces these are the corresponding MAC addresses. Let us check if We can also Yeah, see that 0060 to F2 e e 9 0 1 the MAC address is actually here
