How do I change port to trunk port?
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.
How do I show the trunk of an interface?
To display the status of the trunk, determine the native VLAN used on that trunk link and verify trunk establishment using the show interfaces trunk command. The following output shows that the native VLAN on one side of the trunk link was changed to VLAN 2.
How do you set the trunk port on a Dell switch?

- #switchport access vlan 119.
- #no switchport mode trunk.
Which command disables the trunking configuration on a switch interface?
switchport mode access interface
To avoid trunking misconfigurations, configure interfaces connected to devices that do not support DTP to not forward DTP frames, that is, to turn off DTP. If you do not intend to trunk across those links, use the switchport mode access interface configuration command to disable trunking.
What is 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. The exception to this is when a trunk port is granted access to the untagged VLAN set (native VLAN ID).
How do I add a VLAN to a Dell switch?

How to see if an interface is in Trunk Mode?
The show interface trunk command is very useful. You can see if an interface is in trunk mode, which trunk encapsulation protocol it is using (802.1Q or ISL) and what the native VLAN is. We can also see that VLAN 1 – 4094 are allowed on this trunk.
Can a VLAN be configured in Trunk Mode?
That’s the native VLAN, defaults to 1. Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode. What we’re looking at here is Cisco’s recommended best practices for trunk implementation.
Can a switchport be configured to Trunk Mode?
Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode. Yes, you can see it on the screen. So you would say switchport trunk encapsulation and then you would choose dot1q.
Is the Cisco switch compatible with Layer 3 trunks?
The switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.
