Problems solved by technology

[0043] Based on the above process, it can be seen that the method for implementing port negotiation between FCFs in the prior art can realize the negotiation of VFC ports between FCFs, but this method makes the negotiation process too redundant and causes the negotiation convergence time to be too long

Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0074] The embodiment of the present invention aims at the defect that the port negotiation process between FCFs in the prior art is too redundant and leads to too long convergence time of negotiation, and correspondingly improves the port negotiation process between FCFs.

[0075] Improvement one:

[0076] The division of VLANs has been clarified during network planning, that is, which VLANs run FCoE and have VFC ports added, and which VLANs do not run FCoE but do not contain VFC ports, even if they are mistakenly assigned to belong to a certain VLAN during network planning. If the opposite end of the VFC port does not support the VLAN, it will only cause subsequent negotiation failures and will not affect the normal operation of the network. Therefor...

Abstract

The invention provides a method and device for realizing port consultation between fabric channel over Ethernet (FCoE) forwarders. According to the method and device for realizing the port consultation between the FCoE forwarders, a reciprocal process for an FCoE initialization protocol-virtual local area network (FIP VLAN) request message and a FIP VLAN notification message can be omitted by the port consultation between the FCoE forwarders, and an exchange link parameters (ELP) consultation process, an exchange switch capabilities (ESC) consultation process and an exchange virtual fabrics parameters (EVFP) consultation process in a VLAN are omitted, and therefore, the port consultation between the FCoE forwarders can be simplified.

Description

technical field [0001] The present invention relates to FCoE (Fabric Channel Over Ethernet, Fiber Channel over Ethernet) technology, in particular to a method and device for realizing port negotiation between FCF (FCoE Forwarders, FCoE switches). Background technique [0002] With the continuous development of Internet applications, more and more information and data need to be stored. For this reason, a SAN (Storage Area Networks, storage network) solution is proposed in the prior art, and the storage environment provided by the SAN can meet the requirements for storage, access and backup of large-capacity and high-reliability data. [0003] FC (Fabric Channel, Fiber Channel) is the most widely used protocol in the SAN, that is, the SAN transmits data based on the FC network. Moreover, in order to reduce the equipment cost and maintenance difficulty of the FC network, the existing technology constitutes an FCoE network by carrying FC on the Ethernet, thereby integrating th...
