•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 device 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.
•RADIUS servers cannot assign the default VLAN to 802.1x supplicants by
using Dynamic VLAN Assignment.
When the VID of the default VLAN is changed, the device performs the following
on all the ports in the VLAN, after saving the configuration and rebooting the
device:
•Removes VLAN membership of the ports from the original default VLAN
(possible only after reboot).
•Changes the PVID (Port VLAN Identifier) of the ports to the VID of the new
default VLAN.
•The original default VLAN ID is removed from the device. To be used, it must
be recreated.
•Adds the ports as untagged VLAN members of the new default VLAN.
To change the default VLAN:
STEP 1 Click VLAN Management > Default VLAN Settings.
STEP 2 Enter the value for the following field:
•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 after reboot.
STEP 3 Click Apply.
STEP 4 Click Save (in the upper-right corner of the window) and save the Running
Configuration to the Startup Configuration.
The Default VLAN ID After Reset becomes the Current Default VLAN ID after
you reboot the device.
