VLANS (Cisco Switches - Packet Tracer)
This video describes some advanced topics when using VLANS with multiple Cisco switches. This looks at "per VLAN" spanning tree (PVST). This also shows link aggregation. Note that this topic is before looking at trunking and so no trunks are used. The video does mention that other non-Cisco switches do not support 'per VLAN' spanning tree. This is not true, although they do use a different standard.
