  • Page 18 An egress port is an outgoing port, that is, a port through which a data packet leaves. There are 5 hosts (Host A, B, C, D and E) connected to a 5-port layer-2 switch which supported port-based VLAN.
  • Page 19 Port-based VLAN across different switch • Port-based VLAN is specific only to the switch on which it was created. Definitely, Port-based VLAN can't across different switches. As the following network diagram shown in most MTU case, for the sake of security, subscribers are isolated with each other except for the gateway.

Both Switch A and Switch B will receive this frame and learn MAC address of Host on Port 2.
