Media Access Port

Meaning – The term media access port, refers to a hardware-addressable component (such as a communication adapter) of a node that gives the node access to a transmission medium and enables data to pass into and out of the node.

An access port transports traffic to and from only the specified VLAN allotted to it. Unlike a trunk port, it will not deliver exclusive identifying tags (either 802.1Q or ISL tags) because the VLAN intended for it is pre-assigned.

Usually, an access port will only have a single VLAN set up on the interface and it carries traffic for just a single VLAN. If the VLAN for an access port is not configured, the interface can carry traffic using only the default VLAN, which is usually VLAN1.

Example of usage“It is possible to configure Ethernet interfaces as either access ports or trunk ports, but they are unable to function as both types of port at the same time.”
