A VLAN trunk allows for data to travel across a single link between two devices even if the data is from multiple VLANs. This allows for reduced cabling needed as for you won't have to run multiple cables between switches in order to have up-links for every VLAN.

What is the difference between a access port and a trunk port?

• Access link: An access link is a link that is part of only one VLAN, and normally access links are for end devices. Any device attached to an access link is unaware of a VLAN membership. An access-link connection can understand only standard Ethernet frames. Switches remove any VLAN information from the frame before it is sent to an access-link device.• Trunk link: A Trunk link can carry multiple VLAN traffic and normally a trunk link is used to connect switches to other switches or to routers. To identify the VLAN that a frame belongs to, Cisco switches support different identification techniques (VLAN Frame tagging). Our focus for CCNA examination is on Inter-Switch Link (ISL) and 802.1Q.A trunk link is not assigned to a specific VLAN. Many VLAN traffic can be transported between switches using a single physical trunk link.

What is pvid?

A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.


What is a router on stick inter vlan routing?
