DIS-200G Series Gigabit Ethernet Switch CLI Reference Guide
239
Level: 15.
Usage Guideline
The command only takes effect when the interface is set to trunk mode. When a trunk port native VLAN is set
to tagged mode, normally the acceptable frame type of the port should be set to “tagged- only” to only accept
tagged frames. When a trunk port works in the untagged mode for a native VLAN, transmitting untagged
packet for a native VLAN and tagged packets for all other VLANs and the acceptable frame types of the port
has to be set to “admit-all” in order to function correctly.
The specified VLAN does not need to exist to apply the command.
Example
This example shows how to configure interface port1 as a trunk interface and configures the native VLAN to
20.
Switch# configure terminal
Switch(config)# interface Ethernet 1/0/1
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport trunk native vlan 20
Switch(config-if)#
43-10

Command Default Level
Level: 15.
Usage Guideline
Use the vlan global configuration command to create VLANs. Entering the vlan command with a VLAN ID
enters the VLAN configuration mode. Entering the VLAN ID of an existing VLAN does not create a new VLAN,
but allows the user to modify the VLAN parameters for the specified VLAN. When the user enters the VLAN ID
