Dynamic VLAN Subinterface Creation Overview

After you configure the base profile, you associate it with the VLAN major interface by issuing profile vlan bulk-config command.

As a final step, you must issue auto-configure vlan command. This command configures the VLAN major interface to support autodetection of the VLAN dynamic encapsulation type.

When the router receives an incoming data packet on a circuit, it dynamically creates the VLAN subinterface, using the attributes specified in the base profile. After examining the contents of the data packet, the router dynamically creates the required interface columns above the VLAN subinterface, using the configuration attributes contained in the nested profiles, if specified, or in the base profile itself.
