To create an IP interface (to enable IP-Layer functionality), you must assign a primary IP address to the VLAN or brouter port. By default, the switch enables the IP interface after you configure the primary IP address.

You can administratively enable or disable an IPv4 interface after you create it or you can instruct the switch to create the IP interface in a disabled state when you configure the primary IP address. The following examples provide different use cases to change the administrative state of an IP interface.

To change the feature configuration on an existing IP interface, you must perform the following actions:

  1. Disable the IP interface.

  2. Make the configuration change.

  3. Reenable the IP interface.

To preconfigure a new interface, including routing protocols on the interface, and enable it later during a maintenance window, you can configure the primary IP address for the interface and configure the disabled state simultaneously.
