VLAN Access Overview
SN 5428-2 VLAN access provides IP hosts with access to storage devices according to the VLAN to
which each host belongs.
Figure 1-19 shows a sample network that employs SN 5428-2 VLAN access. In the figure, an SN 5428-2
Gigabit Ethernet interface is connected to an IP network through an IEEE 802.1Q trunk; the SN 5428-2
Fibre Channel interfaces are connected to storage devices 1, 2, and 3. The SN 5428-2 is configured with
two SCSI routing instances named SR100 and SR200. The IP network contains two VLANs: VLAN 100
and VLAN 200. The SCSI routing instance, SR100, is configured to allow the hosts in VLAN 100 to
access storage devices 1 and 2. The SCSI routing instance, SR200, is configured to allow the hosts in
VLAN 200 to access storage device 3.
