Embodiment approach

[0112] Based on the FCoE terminal list, an implementation of this step 20b includes: the FC NPV device receives the LLDP message, parses the LLDP message, and obtains various information in the LLDP message; then, according to the MAC address in the LLDP message, on the FCoE terminal Search in the list.

[0113] If the MAC address in the LLDP message is found in the FCoE terminal list, according to the FCoE identifier in the LLDP message, identify in the FCoE terminal list whether the host device corresponding to the MAC address in the LLDP message supports FCoE. In detail, if the MAC address in the LLDP message is found in the FCoE terminal list, the FC NPV device further determines whether the fcoedevice capability item in the system capabilities of the LLDP message is set; if the fcoedevice capability item in the system capabilities is set , the FC NPV device rewrites the value of the "Does it support FCoE" field corresponding to the MAC address in the FCoE terminal list to...

Abstract

The invention provides a method, device and system for processing a fiber channel identity, and network equipment. The method comprises the following steps of: receiving a first fabric login (FLOGI) or a first fabric discovery (FDISC) sent by host equipment, wherein the first FLOGI or the first FDISC comprises an equipment identifier of an N port of the host equipment; selecting a FC ID (Fiber Channel Identity) from pre-applied non-distributed FC IDs according to the first FLOGI or the first FDISC; and encapsulating the selected FC ID into a first LS_ACC (Link Service Accept) and sending the first LS_ACC to the host equipment. In the technical scheme disclosed by the invention, by pre-applying the FC ID, when the host equipment applies for the FC ID, the FC ID can be directly distributed to the host equipment from the pre-applied FC IDs; therefore, an interaction link is omitted when the host equipment applies for the FC ID; and the problem of FLOGI or FDISC failure of the host equipment caused by delayed FC ID distribution is solved.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, device, system and network equipment for processing identity marks of a fiber channel. Background technique [0002] With the continuous development of network storage and various distributed applications, enterprises and users have higher and higher demands on high-speed communication technology. Fiber Channel (FC) is a high-speed, high-reliability, and high-throughput data transmission system that greatly meets the needs of enterprises and users for high-speed communications. FC can be widely used in high-performance storage, large-scale database and data warehouse, storage backup and recovery, cluster system, network storage system, digital video network and other fields. [0003] FC completely separates the distribution of data from the content of the data, and only cares about the transmission of data, which facilitates the transmission of various data types. F...
