System Overview MP.11-R Installation and Management

Virtual Local Area Networks (VLANs)

Virtual Local Area Networks (VLANs) are logical groupings of network hosts. Defined by software settings, other VLAN

members or resources appear (to connected hosts) to be on the same physical segment, no matter where they are

attached on the logical LAN or WAN segment. They simplify allowing traffic to flow between hosts and their frequently-

used or restricted resources according to the VLAN configuration.

Tsunami MP.11-R units are fully VLAN-ready; however, by default, VLAN support is disabled. Before enabling VLAN

support, certain network settings should be configured and network resources such as VLAN-aware switches should be

available, dependent upon the type of configuration.

VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:

• Manage VLAN configuration from a single window

• Define groups

• Reduce broadcast and multicast traffic to unnecessary destinations

– Improve network performance and reduce latency

• Increase security

– Secure network restricts members to resources on their own VLAN

VLAN tagged data is collected and distributed through a unit’s Ethernet interface. The units can communicate across a

VLAN-capable switch that analyzes VLAN-tagged packet headers and directs traffic to the appropriate ports when the

units are working in their Transparent mode.

VLAN features can be managed via:

• The BSU’s Web interface

• The Command Line Interface (see “Command Line Interface” in the Tsunami MP.11/QB.11 Reference Manual)

• SNMP (see the MIBs provided on the product CD)

For more information about VLAN configuration, see VLAN Parameters.
