Spletframe switching is just the switching process that switches do. Frame flooding is what it's called when the switch doesn't have a mac table entry for the destination and sends that frame out each port that cooperates on that VLAN. So if it's an access port on that vlan, or a trunk port that allows that vlan, it'll send that frame too. It's ...

Switch mainly performs these functions: Learning – The switch learns the MAC address of the device on the switch port on which it receives the frame. (a) Unicast: The switch unicasts the frame to the destination only when it has an … SpletIn that case if there's an address in the CAM table for a specific port, the frame wouldn't need to be sent out that port because the frame doesn't have the same dest MAC as the device connected to that port. This is flawed of course because a switch port can have many MAC addresses associated with it. 1. radicldreamer • 7 yr. ago.
