PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Solaris(TM) Operating System)

2.3.5.1 Redundant Line Control function using Tagged VLAN interface

In Redundant Line Control Function, transfer paths can be multiplexed with tagged VLAN interfaces using an ethernet driver that complies with the tagged VLAN specification.

[Figure 2.48 Using Tagged VLAN Interface architecture]

Even if switches/hubs or NICs come short, using tagged VLAN can provide sufficient number of transfer routes in various network architectures.
When building a server system as three-layered model, it is possible to implement transfer route multiplexing feature on an environment where number of Switch/HUB and NIC is constrained.

[Figure 2.49 When Switch/HUB and NIC come short.]

The following modes support a Tagged VLAN.

• Fast switching mode
• NIC switching mode

Multiplexed transfer routes with Tagged VLAN cannot be used in RIP and GS/SURE linkage modes.

For details on using Tagged VLAN for other modes, refer to "3.7.3 Multiplex transfer route using Tagged VLAN Interface".
