Overview of Using VLANs
VLAN Support and the Default VLAN
In the factory default configuration, all ports on the switch belong to the
default VLAN (named DEFAULT_VLAN). This places all ports in the switch
into one physical broadcast domain. In the factory-default state, the default
VLAN is the primary VLAN.
You can partition the switch into multiple virtual broadcast domains by adding
one or more additional VLANs and moving ports from the default VLAN to the
new VLANs. You can change the name of the default VLAN, but you cannot
change the default VLAN’s VID (which is always “1”). Although you can remove
all ports from the default VLAN, this VLAN is always present; that is, you
cannot delete it from the switch.
The Primary VLAN
Because certain features and management functions, such as single IP-
address stacking, run on only one VLAN in the switch, and because DHCP and
Bootp can run per-VLAN, there is a need for a dedicated VLAN to manage these
