User Guidelines
The command adds a port to the default VLAN as a tagged port.
The command is available only if the port mode is trunk or general.
When a trunk port is a member in the default VLAN as a tagged port then:
•
The native VLAN cannot be the default VLAN
•
The default of the native VLAN is 4095
Note: If the native VLAN of a port is the default VLAN when the port is added to the
default VLAN as tagged, the native VLAN is set by the system to 4095.
When a general port is a member in the default VLAN as a tagged port then:
•
The PVID can be the default VLAN.
•
The default PVID is the default VLAN.
Note: The PVID is not changed when the port is added to the default VLAN as a
tagged.
When executing the switchport default-vlan tagged command, the port is added
(automatically by the system) to the default VLAN when the following conditions
no longer exist:
•
The port is a member in a LAG.
•
The port is 802.1X unauthorized.
•
An IP address is defined on the port.
•
The port is a destination port of port mirroring.
•
An IP address is defined on the default VLAN and the port is a PVE
protected port.
