If a switch receives a frame on a port destined for a mac-address. How does it determine where to look for the destination port with respect to the vlan?
- If the port it was received on is part of a vlan it will only look in that vlan.
- If the port it was received on is a trunk port it will look at the frame's vlan-id.
- It will either send it to a port with a known address or out all ports and trunk ports looking for the address.
