Chapter 12 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 VLANs
When 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 entering the vlan database privileged
EXEC command) does not support the extended range.
Extended-range VLAN configurations are not stored in the VLAN database. Because VTP 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
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.
