Chapter 13 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 gigabitethernet0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end
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). Extended-range VLANs enable service providers to extend their infrastructure
to a greater number of customers. The extended-range VLAN IDs are allowed for any switchport
commands that allow VLAN IDs. You always use config-vlan mode (accessed by entering the vlan
vlan-id global configuration command) to configure extended-range VLANs. The extended range is not
supported in VLAN database configuration mode (accessed by entering the vlan database privileged
EXEC command).
Extended-range VLAN configurations are not stored in the VLAN database, but because VTP mode is
transparent, they are stored in the switch running configuration file, and 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 13-2 for
the actual number of VLANs supported.
These sections contain extended-range VLAN configuration information:
• Default VLAN Configuration, page 13-12
• Extended-Range VLAN Configuration Guidelines, page 13-13
• Creating an Extended-Range VLAN, page 13-13
• Creating an Extended-Range VLAN with an Internal VLAN ID, page 13-15

Default VLAN Configuration

See Tabl e 13-2 on page 13-8 for the default configuration for Ethernet VLANs. You can change only the
MTU size, private VLAN, and the remote SPAN configuration state on extended-range VLANs; all other
characteristics must remain at the default state.
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.
