A port that only allows Ethernet frames of the default VLAN to pass is called an access link type port. The Access port opens the VLAN tag after receiving the Ethernet frame, and strips the VLAN tag when forwarding the port, which is transparent to the end host, so it is usually used to connect and does not need to recognize the 802.1Q protocol (supports tunnel technology, which allows service providers Transmission VLAN, thereby retaining the customer's VLAN) equipment, such as end hosts, routers, etc.
