Chapter13 Configuring VLANs
Configuring Normal-Range VLANs
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 page13-8.)
Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN
database:
To return an interface to its default configuration, use the default interface interface-id interface
configuration command.
This example shows how to configure a port as an access port in VLAN 2:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end
Step4 show vlan brief Verify the VLAN removal.
Step5 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
Command Purpose
Step1 configure terminal Enter global configuration mode
Step2 interface interface-id Enter the interface to be added to the VLAN.
Step3 switchport mode access Define the VLAN membership mode for the port (Layer 2 access
port).
Step4 switchport access vlan vlan-id Assign the port to a VLAN. Valid VLAN IDs are 1to 4094.
Step5 end Return to privileged EXEC mode.
Step6 show running-config interface interface-id Verify the VLAN membership mode of the interface.
Step7 show interfaces interface-id switchport Verify your entries in the Administrative Mode and the Access Mode
VLAN fields of the display.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.
