If the SN 5428-2 is used in a Cisco switched network environment, configure the SN 5428-2 to use the Cisco proprietary VLAN Trunking Protocol (VTP). With VTP, the SN 5428-2 will exchange VTP packets with an externally attached switch to dynamically learn about the VLANs that are accessible in the IP network. The SN 5428-2 then uses VTP to propagate VLAN information around the switched network using layer 2 multicast packets.

If the SN 5428-2 is used in a non-Cisco switched network environment, configure the SN 5428-2 for VLAN without using VTP. The SN 5428-2 does not exchange VTP packets to learn about the VLANs in the network. Instead, you must manually assign VLANs in the network with a VLAN identifier (VID) number. You can optionally assign each VLAN with a unique name and manually set the MTU size.

If the SN 5428-2 participates in a cluster, the VLAN information configured for the SN 5428-2 is propagated to all storage routers in the cluster.

The SN 5428-2 uses IEEE 802.1Q standard for VLAN encapsulation. With 802.1Q encapsulation, VLAN information is carried in packets sent and received through the SN 5428-2 Gigabit Ethernet interface. These packets contain the VID and other VLAN information needed for VLAN members to participate in a VLAN.

A VLAN is granted access to storage devices via a SCSI routing instance configured in the SN 5428-2. The iSCSI targets assigned to the SCSI routing instance determine which storage devices the VLAN can access.

Zoning Overview

The SN 5428-2 supports FC fabric zoning. Zoning enables you to divide the devices of the fabric into zones for more efficient and secure communication among functionally grouped nodes.

Note FC fabric zoning participation is not supported in SN 5428-2s deployed for transparent SCSI routing.

In an IP host, the iSCSI driver is configured with the Gigabit Ethernet IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses. In a storage router, access is controlled through an access list and a VLAN identifier VID number of the hosts. Additionally, access can be further controlled in the SN 5428-2 through authentication.
