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 moves 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.
