An access port can have only one VLAN configured on the interface; it can carry traffic for only one VLAN. A trunk port can have two or more VLANs configured on the interface; it can carry traffic for several VLANs simultaneously.
What is the goal of VLAN trunking?
VLAN trunking enables the movement of traffic to different parts of the network configured as a VLAN. A trunk is a point-to-point link between two network devices that carry more than one VLAN. With VLAN trunking, you can extend your configured VLAN across the entire network.
What is the difference between trunk and access port?
These may also be referred to as "trunk" or "access" respectively. The purpose of a tagged or "trunked" port is to pass traffic for multiple VLAN's, whereas an untagged or "access" port accepts traffic for only a single VLAN. Generally speaking, trunk ports will link switches, and access ports will link to end devices.

What is a VLAN?
VLAN provides multiple virtual networks in a physical network. We can break a local area network into multiple virtual networks. The devices of same virtual network can communicate with each other without interfere to other virtual network. The switchports of a switch can be used as access port or trunk port.
How does VLAN work?
VLAN works as a separate broadcast domain in a LAN. You can say if there are 5 VLANs in a LAN, there are 5 broadcast domains lying in the LAN. Each device belongs to VLAN assume in separate broadcast domain. The access ports in a VLAN works like separate collision domain for the connected device.

Access ports of a Later 3 switch. Access port belongs to a particular VLAN. By default, all access ports of a switch remain in a VLAN 1. It means any device connected with any access port can communicate with another device.
How to add devices to a VLAN?
The devices can be added in a VLAN by two methods static and dynamic. Actually we configure the switchports for access by device with these methods. Generally static method assigned to the VLANs as it is easy and secure method. In static method we add the switchports manually to a VLAN. Suppose I assign the switchport number 4 to VLAN 10. This switchport remains assigned to VLAN unless we manually change it or assign to another VLAN. By default all switchports assigned to a single VLAN. We need to assign each port manually to the required VLAN.
What is a VLAN switch?
The switch provide a single broadcast domain to all connected devices by default. Each port of switch creates single collision domain. VLAN breaks the broadcast domain into small broadcast domain. If we need to make communication between different VLANs then we need a router. Router have the feature to provide communication between different networks. VLAN provides the logical network within a single physical network.
Why should switches be connected to trunk ports?
Both switches should be connected with the trunk port to make communication between all VLANs of different switches. A trunk port can carry the data of all VLANs together for another trunk port. We can say just like a telephone line which can carry multiple voice calls without disturbing each other. The trunk port can carry multiple VLANs data without interfering each other in a network. A trunk link speed may be 100, 1000 or 10000 Mbps point to point link between two switches.
