Configuring VLANs

Configuring a VLAN

Note When you delete a VLAN, ports associated to that VLAN shut down. The traffic does not flow and the packets are dropped.

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# vlan	Creates a VLAN or a range of VLANs.
	{vlan-id vlan-range}	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.
Step 3	switch(config-vlan)# no	Deletes the specified VLAN or range of VLANs and removes you
	vlan {vlan-id vlan-range}	from the VLAN configuration submode. You cannot delete VLAN1
		or the internally allocated VLANs.

This example shows how to create a range of VLANs from 15 to 20:

switch# configure terminal switch(config)# vlan 15-20

Note You can also create and delete VLANs in the VLAN configuration submode.

Configuring a VLAN

To configure or modify the VLAN for the following parameters, you must be in the VLAN configuration submode:

•Name

•Shut down

Note You cannot create, delete, or modify the default VLAN or the internally allocated VLANs. Additionally, some of these parameters cannot be modified on some VLANs.
