When using the factory default settings, the switch automatically creates VLAN 1
as the default VLAN, the default interface status of all ports is Trunk, and all ports
are configured as untagged members of the default VLAN.
The default VLAN has the following characteristics:
•
It is distinct, non-static/non-dynamic, and all ports are untagged members
by default.
•
It cannot be deleted.
•
It cannot be given a label.
•
It cannot be used for any special role such as unauthenticated VLAN or voice
VLAN. This is only relevant for OUI-enabled voice VLAN.
•
If a port is no longer a member of any VLAN, the switch automatically
configures the port as an untagged member of the default VLAN. A port is
no longer a member of a VLAN if the VLAN is deleted or the port is removed
from the VLAN.
When the VID of the default VLAN is changed, the switch performs the following
on all ports in the VLAN:
•
Removes VLAN membership of the ports from the original default VLAN.
•
Changes the PVID of the ports to the VID of the new default VLAN.
•
The original default VLAN ID is removed from the switch. To be used, it must
be recreated.
•
Adds the ports as untagged VLAN members of the new default VLAN.
To change the default VLAN:
Click VLAN Management > Default VLAN Settings.
Enter the following information:
•
Current Default VLAN ID—Displays the current default VLAN ID.
•
Default VLAN ID After Reboot—Enter a new VLAN ID to replace the default
VLAN ID.
