Chapter12 Configuring VLANs
Configuring Extended-Range VLANs
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 gigabitethernet0/17
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end
Switch#
Configuring Extended-Range VLANsWhen the switch is in VTP transparent mode (VTP disabled), you can create extended-range VLANs (in
the range 1006 to 4094 for any switch port commands that allow VLAN IDs). Enter the vlan vlan-id
global configuration command to access config-vlan mode and to configure extended-range VLANs.
The VLAN database configuration mode (that you access by ent ering the vlan database privileged
EXEC command) does not support the extended range.
Extended-range VLAN configurations are not stored in the VLAN database. Because V TP mode is
transparent, they are stored in the switch running configuration file. You can save the configuration in
the startup configuration file by using the copy running-config startup-config privileged EXEC
command.
Note Although the switch supports 4094 VLAN IDs, see the “Supported VLANs” section on page 12-2 for
the actual number of VLANs supported.
This section includes this information about extended-range VLANs:
•Default VLAN Configuration, page 12-12
•Extended-Range VLAN Configuration Guidelines, page 12-12
•Creating an Extended-Range VLAN, page 12-12
•Displaying VLANs, page 12-13
Step4 switchport access vlan vlan-id Assign the port to a VLAN. Valid VLAN IDs are 1 to 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.
