transmitted to port 2,3and 4.
In chart 2, red and blue indicate two different VLANs in the switch, and port 1 and port 2 belong to red
VLAN, port 3 and port 4 belong to blue VLAN. If a broadcast frame is sent out from port 1, switch will
transmit it to port 2, the other port in the red VLAN and not transmit it to port3 and port 4 in blue VLAN. By
this means, VLAN divide the broadcast domain viare stricting the range of broadcast frame transmition.
Note: chart 2 use red and blue to identify the different VLAN, but in practice, VLAN uses different VLAN
IDs to identify.
