VLAN Trunks
▪ A VLAN trunk carries more than one VLAN.
▪ A VLAN trunk is usually established between switches so same-
VLAN devices can communicate, even if physically connected to
different switches.
▪ A VLAN trunk is not associated to any VLANs; neither is the trunk
ports used to establish the trunk link.
▪ Cisco IOS supports IEEE802.1q, a popular VLAN trunk protocol.
