Reference Guide

NOTE: The layer 3 portion of guest VLAN and authentication fail VLANs can be created
regardless if the VLAN is assigned to an interface or not. After an interface is assigned a
guest VLAN (which has an IP address), routing through the guest VLAN is the same as any
other traffic. However, the interface may join/leave a VLAN dynamically.
