In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
It should be noted that term " first " in description and claims of this specification and above-mentioned attached drawing, "
Two " etc. be for distinguishing similar object, without for describing specific order or precedence.
Embodiment one：
Provide a kind of virtual local area network selection method in the present embodiment, Fig. 1 is according to embodiments of the present invention virtual
The flow chart of local network selection method, as shown in Figure 1, the flow includes the following steps：
Step S102, it is virtual to receive the Ethernet optical-fibre channel initializtion protocol that Ethernet Fibre Channel oE nodes are sent
LAN FIP VLAN request messages；
The target of FCoE be continue keep user to the desired high-performance of optical-fibre channel and it is functional under the premise of, will
Storage transmission incorporates Ethernet architecture.FCoE improves flexibility, while also increases the challenge of security, such as FCoE nodes
It is Ethernet switch between FCF (FCoE Forwarder, FCoE transponder), then loses the safety guarantee of point-to-point.
In order to keep being necessary to ensure that from a FCoE node-flow with robustness identical FC (Fiber Channel, optical-fibre channel), FCoE
All FCoE flows for going out or flowing into pass through same FCF, and if multiple FCoE nodes pass through same physics FCF ports
FCF is linked into, these FCoE nodes use the MAC Address distributed.It is equal in this way, can be established between FCoE nodes and FCF
The connection of point-to-point.All FIP agreements are all based on what a VLAN was carried out, in order to provide based on the FCoE equipment on VLAN,
Except FIP VLAN have found agreement, FCoE and FIP other agreements will be all deployed on corresponding VLAN.
In this step, FCoE nodes forward port virtually to forward port to send out to the FCoE of FCF by FCoE node virtuals
FIP VLAN request messages are sent, corresponding, the FIP VLAN requests that the FCoE of FCF virtually forwards port to receive FCoE nodes are reported
Text.

One virtual LAN is arranged to the first virtual LAN in above-mentioned first virtual local area net collective, and it is empty will to be provided with above-mentioned first
The above-mentioned first virtual local area net collective for intending LAN is determined as above-mentioned second virtual local area net collective.
Step S106, above-mentioned FCoE nodes are sent to by above-mentioned FIP VLAN response messages, so that above-mentioned FCoE nodes root
It is used for the virtual LAN for sending Ethernet optical-fibre channel initializtion protocol message according to above-mentioned second virtual LAN Resource selection.
In this step, above-mentioned FIP VLAN response messages are sent to above-mentioned FCoE nodes by FCF, so that above-mentioned FCoE is saved
Above-mentioned first virtual LAN in the above-mentioned second virtual local area net collective of point selection, is sent by above-mentioned first virtual LAN
Above-mentioned Ethernet optical-fibre channel initializtion protocol message.
After operation is started, FCoE nodes or FCF can call FIP VLAN to find agreement to find in lossless Ethernet
VLAN.FIP VLAN have found that agreement is not essential, can be without using if VLAN situations are known or during without using VLAN
FIP VLAN have found agreement.
Method used in the embodiment of the present invention, can realize that selection when FCOE virtual links are established to correct VLAN carries
Protection mechanism has been supplied, has realized the protecting effect for avoiding FCoE nodes from selecting wrong hidden danger when enabled selection VLAN is logged in,
It ensure that the normal foundation of FCOE virtual links, the Ethernet optical fiber sent by receiving Ethernet Fibre Channel oE nodes leads to
Road initializtion protocol virtual LAN FIP VLAN request messages；It is empty according to carried in above-mentioned FIP VLAN request messages first
Intend the first virtual office of LAN and the support Ethernet fiber channel services configured on Ethernet optical-fibre channel transponder FCF
Domain net collective determines the second virtual local area net collective carried in FIP VLAN response messages；By above-mentioned FIP VLAN response messages
Above-mentioned FCoE nodes are sent to, so that above-mentioned FCoE nodes are used to send ether according to above-mentioned second virtual LAN Resource selection
The virtual LAN of net optical-fibre channel initializtion protocol message, compared with prior art, it is virtual to compensate for FCOE in correlation technique
Selection during link establishment to correct VLAN provides protection mechanism, realizes and avoids FCoE nodes from being logged in enabled selection VLAN
When select the protecting effect of wrong hidden danger, ensure that the normal foundation of FCOE virtual links.
Embodiment two：
