Command Modes Global configuration

Command History

Usage Guidelines SVIs are created the first time that you enter the interface vlan vlan-id command for a particular vlan.

The vlan-id corresponds to the VLAN-tag associated with data frames on an IEEE 802.1Q encapsulated

trunk or the VLAN ID configured for an access port.

Note When you create an SVI, it does not become active until it is associated with a physical port.

If you delete an SVI by entering the no interface vlan vlan-id command, the deleted interface is no

longer visible in the output from the show interfaces privileged EXEC command.

Note You cannot delete the VLAN 1 interface.

You can reinstate a deleted SVI by entering the interface vlan vlan-id command for the deleted

interface. The interface comes back up, but much of the previous configuration will be gone.

The interrelationship between the number of SVIs configured on a switch and the number of other

features being configured might have an impact on CPU utilization due to hardware limitations. You can

use the sdm prefer global configuration command to reallocate system hardware resources based on

templates and feature tables. For more information, see the

sdm prefer command.

Examples This example shows how to create VLAN ID 23 and enter interface configuration mode:

Switch(config)# interface vlan 23

Switch(config-if)#

vlan-id VLAN number. The range is 1 to 4094.
