Parameters
vlan-id1: Specifies the ID of the VLAN you want to create or remove, in the range of 1 to 4094.
to vlan-id2: In conjunction with vlan-id1, specify a VLAN ID range you want to create or remove. The
vlan-id2 argument takes a value in the range of 1 to 4094, and must not be less than that of vlan-id1.
all: Creates or removes all existing VLANs except those configured with other functions.
Description
Use the vlan command to create VLANs. If you create only one VLAN, you enter the view of the VLAN
upon its creation; if the specified VLAN already exists, you enter its VLAN view directly.
Use the undo vlan command to remove VLANs.
By default, only VLAN 1 exists in the system.
z VLAN 1 is the default VLAN and cannot be removed.
z You cannot use the undo vlan command to directly remove the VLANs reserved by the protocol,
voice VLAN, control VLANs for Smart Link, probe VLANs for remote mirroring, or VLANs used for
performing any other features. To remove them, you must remove the associations of them with
the features.
z After you use the undo vlan command to remove a VLAN functioning as the default VLAN of a
trunk or a hybrid port, the configuration of the default VLAN on the trunk port or hybrid port does not
change. The port will continue to use the removed VLAN as its default VLAN.
