Default VLAN Settings
When using factory default settings, the device 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 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.
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 (takes effect
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:
1. Click
Configuration > VLAN Management > VLANs
.
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.
3. Click Apply.
4. Click Save 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.
Creating VLANs
You can create a VLAN, but this has no effect until the VLAN is attached to at least one port,
either manually or dynamically. Ports must always belong to one or more VLANs.
