VLANs are used to separate different broadcast domains. For every VLAN created, another broadcast domain is also created. The VLAN is created globally and applied to the interface. Once the interface has been placed into the VLAN, it becomes a member of that broadcast domain, where it can begin sending and receiving traffic.
Create VLANs 41, 42, 46, 49, 413, 414, 422 and 423 on SW4.
Create VLANs 31, 32, 36, 39, 313, 314, 322 and 323 on SW3.
