Chapter 13 Configuring VLANs

Configuring Normal-Range VLANs

Caution When you delete a VLAN, any ports assigned to that VLAN become inactive. They remain associated with the VLAN (and thus inactive) until you assign them to a new VLAN.

Beginning in privileged EXEC mode, follow these steps to delete a VLAN on the switch:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	no vlan vlan-id	Remove the VLAN by entering the VLAN ID.
Step 3
	end	Return to privileged EXEC mode.
Step 4
	show vlan brief	Verify the VLAN removal.
Step 5
	copy running-config startup config	(Optional) If the switch is in VTP transparent mode, the VLAN
		configuration is saved in the running configuration file as well as in
		the VLAN database. This saves the configuration in the switch startup
		configuration file.

To delete a VLAN by using VLAN database configuration mode, use the vlan database privileged EXEC command to enter VLAN database configuration mode and the no vlan vlan-idVLAN database configuration command.

Assigning Static-Access Ports to a VLAN

You can assign a static-access port to a VLAN without having VTP globally propagate VLAN configuration information by disabling VTP (VTP transparent mode).

If you are assigning a port on a cluster member switch to a VLAN, first use the rcommand privileged EXEC command to log in to the cluster member switch.

Note If you assign an interface to a VLAN that does not exist, the new VLAN is created. (See the “Creating or Modifying an Ethernet VLAN” section on page 13-9.)

Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN database:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode
Step 2
	interface interface-id	Enter the interface to be added to the VLAN.
Step 3
	switchport mode access	Define the VLAN membership mode for the port (Layer 2 access
		port).
Step 4
	switchport access vlan vlan-id	Assign the port to a VLAN. Valid VLAN IDs are 1 to 4094.
Step 5
	end	Return to privileged EXEC mode.
Step 6
	show running-config interface interface-id	Verify the VLAN membership mode of the interface.
