Configuring the Switch Modules using the Command Line Interface
Default VLAN
The switch module reserves one VLAN, VID 1, also called DEFAULT_VLAN. The factory
default setting assigns all ports on the switch module to the default VLAN. As new VLANs
are configured, their respective member ports are removed from the default VLAN.
Characteristics of DEFAULT_VLAN include:
•
•
•
•
•
•
•
•
•
DEFAULT_VLAN is an IEEE 802.1Q Static VLAN with VID equal to 1.
DEFAULT_VLAN cannot be deleted.
The VID cannot be changed. The VID that is equal to 1 is reserved for
DEFAULT_VLAN.
The VLAN name can be changed to any other valid VLAN name.
You cannot delete a port from DEFAULT_VLAN, unless it is a member of another
802.1Q VLAN.
You cannot forbid a port from DEFAULT_VLAN, unless it is a member of another
802.1Q VLAN.
If a port is deleted from the only 802.1Q VLAN of which it is a member, then it will
automatically become a member of DEFAULT_VLAN as an untagged, egress port.
If a port is assigned to a user-created 802.1Q VLAN, and is not a tagged egress port
member of DEFAULT_VLAN (in other words, it is an untagged egress port), then it will
be deleted automatically from DEFAULT_VLAN.
A tagged egress port of DEFAULT_VLAN will not be deleted from DEFAULT_VLAN,
when it is assigned to another user-created 802.1Q VLAN.
The following shows the VLAN factory default settings:
Feature Default Value
Static VLAN Entry Default VLAN (VID = 1)
Port VLAN ID (PVID) 1
Port GVRP Setting Off
Port Ingress Filtering Off
