Creating virtual local area networks vlans understanding the creation and management of vlans in todays modern networks is crucial to a successful network engineer. On s1, issue the command that displays all vlans configured. Vlan tags are used on trunk links in order for the devices usually switches, sometimes routers or servers on each end to be able to tell which frames belong to which vlans.
Vlan tagging, also known as frame tagging, is a method developed by cisco to help identify packets travelling through trunk links.
