Configuring a VLAN
Creating and Deleting a VLAN
You can create or delete all VLANs except the default VLAN and those VLANs that are internally allocated
for use by the switch. Once a VLAN is created, it is automatically in the active state.
When you delete a VLAN, ports associated to that VLAN shut down. The traffic does not flow and the
Note
packets are dropped.

Purpose
Enters global configuration mode.
Creates a VLAN or a range of VLANs.
If you enter a number that is already assigned to a VLAN, the switch
puts you into the VLAN configuration submode for that VLAN. If
you enter a number that is assigned to an internally allocated VLAN,
the system returns an error message. However, if you enter a range
of VLANs and one or more of the specified VLANs is outside the
range of internally allocated VLANs, the command takes effect on
only those VLANs outside the range. The range is from 2 to 4094;
VLAN1 is the default VLAN and cannot be created or deleted. You
cannot create or delete those VLANs that are reserved for internal
use.
Deletes the specified VLAN or range of VLANs and removes you
from the VLAN configuration submode. You cannot delete VLAN1
or the internally allocated VLANs.
