What is the purpose of a trunk port on a switch?

A trunk port is a type of connection on a switch that is used to connect a guest virtual machine that is VLAN aware. Generally, all frames that flow through this port are VLAN tagged.

What is the difference between trunk and access port?

access port – a port that can be assigned to a single VLAN. trunk port – a port that is connected to another switch. This port type can carry traffic of multiple VLANs, thus allowing you to extend VLANs across your entire network. Frames are tagged by assigning a VLAN ID to each frame as they traverse between switches.

What happens if u connect PC to a trunk port?

Yes. Trunk ports can carry both tagged and untagged packets. Untagged packets get put on whatever is configured as the native vlan for the port.

When would you use a trunk port?

A trunk port allows you to send all those signals for each switch or router across a single trunk link. In contrast to an access port, a trunk port must use tagging in order to allow signals to get to the correct endpoint. Trunk ports typically offer higher bandwidth and lower latency than access ports.

Does a trunk port need an IP address?

The router needs to have an IP address/mask associated with each VLAN on the trunk. However, the router has only one physical interface for the link connected to the trunk.

Can you trunk a switch to a router?

The trunk link from the first switch to the router can also carry all four VLANs. In fact, this one connection to the router allows the router to appear on all four VLANs, as if it had four different physical ports connected to the switch.

Why is a trunk port necessary?

What is trunking Cisco?

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. Ethernet trunks carry the traffic of multiple VLANs over a single link, and you can extend the VLANs across an entire network.

What is difference between VLAN access and trunk mode?

The trunk port supports only the tagged frames, whereas the Access port sends and receives untagged frames. The trunk port allows us to switch multiple VLANs, but all frames are in the same VLAN in the Access port.

Can switches communicate with VLAN trunks?

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.

Can 2 switches have the same VLAN?

Yes, assuming the switches are connected together and VLAN 10 is forwarding on the connected ports. Both ports have to be configured the same, so that VLAN 10 is either tagged on both or untagged (native) on both.
