Chapter 12 Configuring VLANs
Configuring Normal-Range VLANs
Beginning in privileged EXEC mode, follow these steps to delete a VLAN on the switch by using global
configuration mode:
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-id VLAN 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 12-8.)
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
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.
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.
Step 7
show interfaces interface-id switchport Verify your entries in the Administrative Mode and the Access Mode
VLAN fields of the display.
Step 8
copy running-config startup-config (Optional) Save your entries in the configuration file.
