7.4.2.2 VLAN
A physical network can be split into logical segments to create multiple Virtual Local
Area Networks (VLANs).
A VLAN gathers a group of devices that may be located anywhere on a network, but
which communicate as if they were on the same physical network:
Setting up a Virtual Local Area Network (VLAN) is more flexible than traditional
networks and easier to manage:
•
Ease the relocation of devices on networks (no re-cabling)
•
Extra security: devices within each VLAN can only communicate with other
devices on the same VLAN. If a device on VLAN A needs to communicate with
devices on VLAN B, the traffic must pass through a routing device.
•
Restricted traffic: with traditional networks, traffic is directed to all network
devices, regardless of whether or not they need it and may cause network
congestion. VLANs are set up to contain only those devices that need to
communicate with each other.
VLANs can manage traffic flow through Reason H49 to improve bandwidth utilization
and security.
To configure virtual LANs in Reason H49, click Network > VLAN .

Reason H49 can manage up to 4096 configurable Virtual LANs. Each VLAN (starting
from 2) can handle up to six VLAN ports.
