Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a configuration information notification method and apparatus for an interface extension device.
Background
With the continuous development of network technology, the interactive data volume is continuously increased, the data center of an enterprise inevitably generates some management problems, the use efficiency of a processor is improved through virtualization, and the cost is further reduced, in order to adapt to the development, a series of new 802.1 standards are proposed by an IEEE organization (Institute of Electrical and Electronics Engineers ) aiming at new technologies such as data center virtual machine migration, and the like, including congestion notification 802.1Qau, enhanced transmission selection 802.1Qaz, priority-based flow control 802.1Qbb, edge virtual bridge 802.1Qbg, virtual bridge port extension 802.1BR, and the like.
802.1Qbg introduces a Virtual border interface Aggregator (VEPA), which sends all information to the border bridge, so that the use of an ACL (Access Control List) is no longer dependent on the location of the Virtual machine. The VDP protocol implements discovery and configuration of a VSI (Virtual Switch Interface), the CDCP protocol implements discovery and configuration of a channel, and the VEPA protocol can reduce complexity related to highly virtualized deployment. The edge intermediate-level method is simple, and the format of the message transmitted on the current link does not need to be modified. However, when multicast or a large amount of information passes through the physical link, there may be multiple identical frame copies of a frame in the physical link, since one frame copy may be sent on each channel.
In order to solve the problem that the 802.1Qbg occupies the bandwidth due to the occurrence of a plurality of identical frame copies, the 802.1BR adds additional tag information, and limits that only one frame copy can be sent and copied through the tag information, so as to reduce the bandwidth occupation under the multicast condition, which is usually realized through hardware setting. The 802.1BR standard can deploy a remote switch as a policy control switch in a virtual environment, rather than as a switch adjacent to a server rack, and by means of a plurality of virtual channels, an edge virtual bridge copies frames to a group of remote interfaces, and a network is designed flexibly by means of a waterfall type serial interface, so that bandwidth is more effectively allocated to multicast frames, broadcast frames and unicast frames. The operations, interaction protocols, management objects and algorithms of the extension bridge are defined for the 802.1BR standard as follows:
1) defining a tag which supports E-CID to realize flow distinguishing and isolation between interfaces on an expansion bridge;
2) establishing an expansion bridge system which comprises a control bridge and one or more interface expansion devices;
3) defining the requirements of the attachment of the interface expansion equipment on bridge construction elements and a system;
4) extending MAC service extension of the bridge interface to bridge interface extension equipment and supporting a user VLAN;
5) defining a PE CSP Protocol (Client Server Protocol), configuring and monitoring bridge interface expansion equipment through a control bridge;
6) the requirement for defining Bridge management, management object and management operation 1BR protocol establish an extended Bridge system, which includes a Control Bridge (CB) and one or more interface extension devices (PE).
In the 1BR vertical stack environment, the core of the zero deployment of the PE device is the plug and play of the PE device. The PE device can achieve the purpose of self-starting and normal operation of the service without directly configuring the PE device through any CLI (Command Line Interface) or network manager, and only manual configuration is performed on the CB device as if a Line card is inserted. One of the prerequisites for zero deployment of a vertically stacked PE device is not any special configuration of the device at the time of shipment and is capable of identifying a vertically stacked environment and a non-vertically stacked environment. Because the PE device in the vertical stack environment is plug-and-play, and a Link between the CB device and the PE device is not fixed, the PE device needs to dynamically sense an uplink LACP (Link Aggregation Control Protocol) Link member port, and in order to implement zero deployment, the PE device needs to sense information such as a PE device version file storage path, version compiling time, version number, and the like. In the prior art, the PE device cannot dynamically sense the information of the member port and version file of the uplink LACP link.
