Can switches communicate with VLAN trunks?
2.1) A VLAN trunk, or trunk, is a point-to-point link between two network devices that carries more than one VLAN. VLAN trunks allow all VLAN traffic to propagate between switches, so that devices which are in the same VLAN, but connected to different switches, can communicate without the intervention of a router.
What is a VLAN trunk port on a switch?
Information About VLAN Trunks. Trunking Overview. A trunk is a point-to-point link between one or more Ethernet switch interfaces and another networking device such as a router or a switch.

How does VLAN Trunking work on a router?
On the first switch, VLAN A and VLAN B are sent through a single port (trunked) to the router and through another port to the second switch. VLAN C and VLAN D are trunked from the second switch to the first switch, and through the first switch to the router. This trunk can carry traffic from all four VLANs.

How are the VLANs of a LAN switch connected?
In the image above, each switch has two VLANs. On the first switch, VLAN A and VLAN B are sent through a single port (trunked) to the router and through another port to the second switch.

What does a trunk port do on a switch?
Trunk Port – The frames received on the interface are assumed to have VLAN tags. Trunk ports are for links between switches or other network devices and are capable of carrying traffic for multiple VLANs. Note: By default, all interfaces are in trunk mode, which means they can carry traffic for all VLANs.
