Configuring Dynamic 802.1Q VLANs
54
You can configure the router to dynamically create VLANs when a client accesses an
interface and requests a VLAN ID that does not yet exist. When a client accesses a VLAN
interface, the router instantiates a VLAN dynamic profile that you have associated with
the interface. Using the settings in the dynamic profile, the router extracts information
about the client from the incoming packet (for example, the interface and unit values),
saves this information in the routing table, and creates a VLAN or stacked VLAN ID for
the client from a range of VLAN IDs that you configure for the interface.
