A trunk port can have two or more VLANs configured on the interface; it can carry traffic for several VLANs simultaneously..

Can we connect PC to trunk port?

Yes, of course. You configure it like a normal trunk. If the PC on the other side doesn’t support VLANs, you will be able to sniff traffic with Wireshark but not to communicate. If the NIC supports VLAN, you can even have an IP in each VLAN and even do routing.

Can an access port have multiple VLANs?

No, an access port can only be part of one VLAN. The trunk ports on the two switches need to be configured to forward the VLAN 10 packets, then all hosts on all VLAN 10 access ports will be able to communicate.

How do you trunk a VLAN?

To enable trunk links, configure the ports on either end of the physical link with parallel sets of commands. To configure a switch port on one end of a trunk link, use the switchport mode trunk command. With this command, the interface changes to permanent trunking mode.

Does a trunk port need a native VLAN?

If you do not configure a native VLAN ID, the trunk port uses the default VLAN. By default, a trunk port sends traffic to and receives traffic from all VLANs. … However, you can remove VLANs from this inclusive list to prevent traffic from the specified VLANs from passing over the trunk.

How do I test a trunk port?

Use the show interfaces trunk command to check whether a trunk has been established between switches. Statically configure trunk links whenever possible. Cisco Catalyst switch ports use DTP by default and attempt to negotiate a trunk link.

When should you use a trunk port?

Trunk port allows us to switch multiple VLANs but in Access port all frames are in the same VLAN. Trunk port basically used to connect between switches however, the access port is used to connect computer laptops, printers, etc. We cannot extend the data from one switch to another switch, access ports via a trunk port.

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

access port – a port that can be assigned to a single VLAN. The frames that arrive on an access port are assumed to be part of the access 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.

What is trunk port in VLAN?
