During the transmission process, VFT_Headers are added to and removed from the frames. A switch can
use the same physical interface to support multiple VSANs. The trunk VSAN technology reduces the
number of physical connections, actually implementing logical isolation in a physical network.
Trunk VSAN in an FCoE network
FCoE carries FC over Ethernet. In an FCoE network, VSANs in FC need to be mapped to VLANs as
configured by the user, and the FIB table for a VSAN is also stored to the relevant VLAN. FCoE packets
use VLAN_Header in replace of VFT_Header in FC packets and are forwarded based on the VLAN ID
in VLAN_Header.
A VFC interface can only work as a trunk port, and the bound Ethernet interface must also be configured
as a trunk port and has the same trunk VLAN list as the VFC interface. In this manner, an FCoE packet
transmitted from a VFC can use the VLAN ID in VLAN_Header to identify the VLAN to which it belongs.

Creating a VSAN

Initially, only the default VSAN (VSAN 1) exists. You cannot create or delete VSAN 1. You can create
VSANs 2 to 3839.
To create a VSAN:
Step
1. Enter system view.
2. Create a VSAN and enter VSAN view.

Configuring a trunk VSAN

A VFC interface can be assigned to multiple VSANs as a trunk port.
If you assign an interface to VSANs as a trunk port multiple times, the final trunk VSAN list is the set of
all the VSANs to which you have assigned the interface.
To assign a VFC interface to the specified VSANs as a trunk port:
VSAN 1
FC Fabric

FC switch A
VSAN 2

By default, only the default VSAN
vsan vsan-id
(VSAN 1) exists.
