Configuring VLANs
Beginning in privileged EXEC mode, follow these steps to delete a VLAN on the switch by using global
configuration mode:
Command
Step 1
configure terminal
Step 2
no vlan vlan-id
Step 3
end
Step 4
show vlan brief
Step 5
copy running-config startup config
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.
If you assign an interface to a VLAN that does not exist, the new VLAN is created. (See the
Note
or Modifying an Ethernet VLAN" section on page
Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN
database:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
switchport mode access
Step 4
switchport access vlan vlan-id
Step 5
end
Step 6
show running-config interface interface-id
Step 7
show interfaces interface-id switchport
Step 8
copy running-config startup-config

Purpose
Enter global configuration mode.
Remove the VLAN by entering the VLAN ID.
Return to privileged EXEC mode.
Verify the VLAN removal.
(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.
12-8.)
Purpose
Enter global configuration mode
Enter the interface to be added to the VLAN.
Define the VLAN membership mode for the port (Layer 2 access
port).
Assign the port to a VLAN. Valid VLAN IDs are 1 to 4094.
Return to privileged EXEC mode.
Verify the VLAN membership mode of the interface.
Verify your entries in the Administrative Mode and the Access Mode
VLAN fields of the display.
(Optional) Save your entries in the configuration file.
