Cannot be given a label.
•
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.
•
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 following information:
•
Current Default VLAN ID
—Displays the current default VLAN ID.
•
Default VLAN ID
—Enter a new VLAN ID to replace the default VLAN ID.
STEP 3
Click
Apply
. The default VLAN is changed, and the Running Configuration is
updated.
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.
Each VLAN must be configured with a unique VID (VLAN ID) with a value from 1 to
4094. The switch reserves VID 4095 as the Discard VLAN. All packets classified to
the Discard VLAN are discarded at ingress, and are never forwarded to a port.
