Video description
A switch port can work in two modes: access mode and trunk mode. In access mode, it removes vlan information from all frames before forwarding them. In trunk mode, it keeps vlan information. Based on the configured mode, it is known as either an access port or a trunk port. If we configure a switch port in access mode, it will be called an access port. If we configure it in trunk mode, it will be known as a trunk port.
A switch uses vlan information to group devices and creates boundaries for broadcast messages. A VLAN is a switch-only feature. End devices do not understand VLAN information. If we connect an end device with a trunk port, the end device will receive frames with the vlan information. Since an end device does not understand frames containing vlan information, it drops them.
An end device will accept frames only when it receives them in their original formats. An access port forwards frames in their original formats. Because of this, we always connect an end device only with an access port. We use a trunk port to connect the switch port with another switch or a router.
Differences between an access port and a trunk port
An access port belongs to only one VLAN.
A trunk port belongs to all VLANs.
An access port forwards the frame in its original format.
A trunk port forwards the frame after adding the VLAN header.
An access port connects an end device to the network.
A trunk port extends the network.
By default, all switch ports are access ports.
By default, no switch port is a trunk port.
