Usage Guidelines
SVIs are created the first time 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.
When you create an SVI, it does not become active until it is associated with a physical port.Note
If you delete an SVI using the no interface vlan vlan-id command, it is no longer visible in the output from
the show interfaces privileged EXEC command.
You cannot delete the VLAN 1 interface.Note
You can reinstate a deleted SVI by entering the interface vlan vlan-id command for the deleted interface.
The interface comes back up, but the previous configuration is gone.
The interrelationship between the number of SVIs configured on a switch or a switch stack 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.
You can verify your setting by entering the show interfaces and show interfaces vlan vlan-id privileged
EXEC commands.
