VLANs provide users the ability to partition devices and subnets on our network. VLANs may be managed within the Customer Portal at any time from the VLANs screen, which displays a variety of information about the VLAN and provides access to each VLAN, along with its associated devices and/or subnets. As an added service, users may enable VLAN Spanning, which connects all private network VLANs on an account, allowing devices on separate VLANs to communicate with each other.
