本申请基于申请号为201610411088.5、申请日为2016年6月13日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的内容在此引入本申请作为参考。
技术领域
本发明涉及通信技术，具体而言，涉及一种虚拟扩展端口的指示方法和装置、存储介质。
背景技术
随着数据中心的快速发展，可通过虚拟化提高处理器的使用效率来进一步降低成本。随着云计算的发展，虚拟机的猛增，企业的数据中心也不可避免的产生了一些管理的难题，为了使网络技术的发展适应新的虚拟化技术趋势，电气和电子工程师协会(IEEE，Institute of Electrical and Electronics Engineers)组织针对数据中心虚拟机迁移等新技术提出了一系列新的802.1标准，包括拥塞通告(Congestion notification)IEEE 802.1Qau、增强传输选择技术(ETS，Enhanced Transmission Selection)IEEE 802.1Qaz、基于优先级的流控(PFC，Priority-based Flow Control)IEEE 802.1Qbb、边缘虚拟桥(Edge Virtual Bridging)802.1Qbg、虚拟桥接口扩展(Bridge Port Extension)802.1BR等。
扩展桥(Extended Birdge，又称纵向堆叠)使用802.1BR标准，纵向堆叠的体系结构一般包括2个重要的部分：控制网桥(CB，Controlling Bridge)和接口扩展设备(PE，Port Extended)。纵向堆叠可将远程交换机部署为CB， 将实体接入交换机或软件虚拟交换机部署为PE，通过设置CB的级联口和PE的上行口在CB和PE之间建立多个扩展通道(E-Channel，Extended Channel)，CB负责为每一个PE端口生成对应的虚拟扩展接口(BEP，Bridge Extended Port)，并分配对应的扩展通道标识(E-CID，E-channel Identifier)，还负责转发单播报文，是多播转发的起点；PE不用进行媒体介入控制层(MAC，Media Access Control)学习，而根据E-CID进行转发，从而解决数据中心中由于虚拟机的激增而引发的管理难题。
在802.1BR标准中，规定了CB和PE使用链路层发现协议(LLDP，Link Layer Discovery Protocol)报文来发现对端设备，CB通过端口扩展控制和状态协议(PE CSP，Port Extender Control and Status Protocol)报文发现PE端口，创建对应的BEP口，并为端口分配E-CID，从而组建纵向堆叠网络。
以CB和1个PE之间创建2个扩展端口为例，如图1所示，交互过程主要包括以下步骤：
步骤S101，CB的一个端口通过LLDP协议发现对端PE设备，初始化一个内部接口扩展设备，并在该端口开启PE CSP协议，同样的，PE的一个端口通过LLDP协议发现对端CB设备，并在该端口开启PE CSP协议；
步骤S102，CB和PE通过对应的端口向对端发送CSP开启(Open)消息，并在收到对端发来的CSP Open消息后，向对端发送CSP Open reply(应答)消息；
步骤S103，CB向PE发送端口参数集(Port Parameters Set)消息，要求PE设置上行口的参数，PE设置完上行口参数后，会向CB发送Port Parameters Set Reply消息；
步骤S104，PE为本设备除上行端口外的2个端口依次向CB申请创建扩展端口，即PE通过上行口向CB先后发送扩展端口创建(Extended Port  Create)消息，来请求CB创建对应的扩展接口、E-channel，并将E-channel绑定到扩展接口；
步骤S105，CB收到Extended Port Create消息后，创建对应的BEP接口并分配E-CID，CB先后向PE发送Extended Port Create Reply消息；
步骤S106，PE收到Extended Port Create Reply消息，将CB分配的E-CID值与端口间的对应关系写入到PE中；
步骤S107，CB先后向PE发送两个Port Parameters Set消息，来设置PE上两个BEP口的参数，如虚拟局域网(VLAN，Virtual Local Area Network)、端口属性等信息；
步骤S108，PE收到Port Parameters Set消息中携带的参数信息，将对应端口设置完毕后向CB发送Port Parameters Set Reply消息。
其中，在步骤S104中，在CB收到的来自PE的Extended Port Create消息中含有命令(Command)类型-长度-值(TLV，Type-Length-Value)，其索引(index)域用于表征对应的一个PE端口，此处的index域中含有12比特(bit)的端口序列号(PortNum)字段，用来表示端口，但802.1BR标准没有规定这12比特的PortNum字段的具体构成，各厂商一般给该字段赋予一个全局唯一标识的PE端口的、无具体意义的数字索引，根据这12比特的数字索引生成的BEP端口的端口名不含有PE端口的具体信息，比如一个PE上的port 1和port 2端口要创建BEP端口，则PE向CB发送2个PE CSP Extended Port Create消息，分别携带了对应PE端口的12比特数字索引。CB上根据收到的12比特数字索引生成2个BEP端口，BEP端口名称可能为BEP M、BEP N，并为BEP M和BEP N这2个端口分配相应的E-CID，其值可能为X和Y；CB将分配的E-CID值通过PE CSP Extended Port Create Reply消息通知PE，此时BEP端口创建成功。但是生成的BEP M和BEP N无任何实际意义，使用时必须以当初分配的E-CID值为索引分别在 CB和PE上进行查询，进行比较后才能找到PE上Port 1对应的CB上BEP M，Port 2对应的BEP N。
实际应用中，常常需要对BEP端口进行业务配置、管理、监控等操作，按照现有的端口解析方法进行操作时，操作较为繁琐，从而影响对BEP端口的配置、管理及监控效率。
针对相关技术中对BEP端口的管理效率较低的技术问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
根据本发明实施例，提供了一种虚拟扩展端口的指示方法的方法实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
将现有的遵循802.1BR协议标准对Extended Port Create消息中携带的12比特的PortNum字段不进行解析方式生成的扩展端口命名方式可简称为简单接口模式(Simple-Interface Mode)，此模式生成的BEP端口名不含实际意义，需要用分配的E-CID查找PE上的对应端口，不便于对端口的管理，为了解决该问题，本发明实施例提出了如下方法来提高端口的管理效率。
图2是根据本发明实施例的虚拟扩展端口的指示方法的流程图，如图2所示，该方法包括如下步骤：
步骤S201，接收请求为接口扩展设备的物理扩展端口创建虚拟扩展端口的请求信息，其中，请求信息中携带有物理扩展端口的端口信息。
步骤S202，创建请求信息所请求创建的虚拟扩展端口，并为创建的虚 拟扩展端口分配扩展通道标识。
步骤S203，基于物理扩展端口的端口信息生成创建的虚拟扩展端口的身份信息。
步骤S204，发送身份信息和分配的扩展通道标识至接口扩展设备。
通过上述实施例，接收请求为接口扩展设备的物理扩展端口创建虚拟扩展端口的请求信息，请求信息中携带有物理扩展端口的端口信息；创建请求信息所请求创建的虚拟扩展端口，并为创建的虚拟扩展端口分配扩展通道标识；基于物理扩展端口的端口信息生成创建的虚拟扩展端口的身份信息；发送身份信息和分配的扩展通道标识至接口扩展设备，由于是基于物理扩展端口的端口信息生成的虚拟扩展端口的身份信息，接口扩展设备在接收到虚拟扩展端口(即BEP端口)的身份信息时即可确定对应的物理扩展端口，以便于管理，从而解决了相关技术中对BEP端口的管理效率较低的技术问题，实现了提高BEP端口的管理效率的技术效果。
可选地，上述步骤的执行主体可以为控制网桥等，但不限于此。
上述的虚拟扩展端口的身份信息是指用于标识虚拟扩展端口的身份的信息，身份信息包括但不局限于虚拟扩展端口的端口名；上述的物理扩展端口的端口信息包括但不局限于端口位置信息(如端口物理地址)。后续以端口名和端口位置信息为例详述本申请的实施例。
需要说明的是，上述的请求信息可以为Extended Port Create消息；发送身份信息和分配的扩展通道标识时，可以将信息携带于Extended Port Create Reply报文中。
在上述实施例中，基于物理扩展端口的端口信息生成创建的虚拟扩展端口的身份信息包括：获取保存的身份信息生成方式；按照保存的身份信息生成方式生成对应于创建的虚拟扩展端口的且携带物理扩展端口的端口信息的身份信息。保存的身份信息生成方式为基于物理扩展端口的端口信 息生成端口名的方式。
上述的虚拟扩展端口生成身份信息(即命名)的方式可称为详细接口命名方式(Detail-Interface Mode)，在Extended Port Create消息中携带PE端口信息，例如端口物理位置信息，生成的BEP端口名中包含PE上具体端口的信息，例如物理位置信息。
可选地，身份信息生成方式包括用户指定的生成方式(可以是用户自定的生成方式，也可以是上述的简单接口命名方式，本申请对此不做限定)和基于物理扩展端口的端口信息生成的方式，保存的身份信息生成方式为基于物理扩展端口的端口信息生成的方式，在生成创建的虚拟扩展端口的身份信息之后，若接收到配置指令，则判断配置指令所指示的身份信息生成方式与保存的身份信息生成方式是否相同；在配置指令所指示的身份信息生成方式与保存的身份信息生成方式不相同的情况下，将保存的身份信息生成方式配置为配置指令所指示的身份信息生成方式。
采用详细接口命名方式，在接收到PE发送的Extended Port Create消息后生成带有PE物理端口位置的BEP端口名(即上述的虚拟扩展端口的身份信息)并分配E-CID(即扩展通道标识)。如果要切换到简单接口命名方式，则删除现有的BEP端口名及E-CID，重新要求PE发送Extended Port Create消息后，按简单接口命名方式重新生成BEP端口名称及E-CID。该方法可为用户提供便于实际商用的带有物理位置的BEP端口命名方式，也提供了满足不同厂商对接兼容性要求的简单化BEP端口命名方式，实现了为不同的用户提供有区别的服务，可使用户体验较好。
无论是处于简单接口方式模式还是详细接口命名方式下，均可以自由切换到另外一种方式重新生成BEP端口名，以实现为不同的用户提供有区别的服务，用户体验较好。下面结合图3详述本发明的实施例，如图3所示：
步骤S301，在CB上配置详细接口命名方式的BEP端口生成方式，并记录下该配置的方式类型。
例如，可以设置的BEP端口生成方式包括简单接口命名方式和详细接口命名方式。
步骤S302，CB接收来自PE的Extended Port Create消息。
步骤S303，CB对消息中Command TLV中的12比特数字索引进行解析。
步骤S304，CB读取BEP端口生成方式配置，如果是详细接口命名方式，则生成带PE物理端口位置的BEP端口名。
例如，生成带PE物理端口位置的BEP端口名，其格式包括但不限于如下形式：“BEP a/b/c/d/e”，其中，“a”代表PE-ID，即接口扩展设备的编号，“b”代表shelf-id，即机框的编号，“c”代表slot-id，即业务板卡所在的槽位的编号，“d”代表sub-slot-id，即子槽位的编号，“e”代表port-id，即端口序号。
步骤S305，CB对BEP端口分配E-CID。
步骤S306，CB将生成的BEP端口和E-CID对应关系以Extended Port Create Reply消息发给PE。
步骤S307，PE收到Extended Port Create Reply消息后将端口以及E-CID值对应关系记录到本地数据库中。
步骤S308，判断BEP口生成方式配置类型，若是简单接口命名方式则执行步骤S309。
可在CB上设置简单接口命名方式的BEP端口生成方式，并记录下该配置的方式类型。
步骤S309，CB检查现有BEP端口生成方式，如果不是简单接口命名方式则删除现有的BEP端口名以及E-CID。
可选地，在将保存的身份信息生成方式配置为配置指令所指示的身份信息生成方式之后，可删除已创建的虚拟扩展端口和对应的扩展通道标识；发送指示删除扩展通道标识的信息至接口扩展设备。具体可通过下述的步骤实现。
步骤S310，CB发送Extended Port删除(Delete)消息给PE。
步骤S311，PE删除本地端口以及E-CID信息，并重新发送Extended Port Create给CB。
步骤S312，CB读取BEP端口生成方式配置，如果是简单接口命名方式，则生成不带PE物理端口位置的BEP端口。
例如，生成不带PE物理端口位置的BEP端口，其格式可以为“BEP M”，但不限于此，“M”为CB分配给BEP端口的一个随机值。
步骤S313，CB对新生成BEP端口分配E-CID。
步骤S314，CB将新生成的BEP端口(或BEP端口名)和E-CID对应关系以Extended Port Create Reply消息发给PE。
步骤S315，PE收到Extended Port Create Reply消息后将端口以及E-CID对应关系记录到本地数据库中。
为实现上述方法，本发明还提供一种网络设备，如图4所示，该网络设备包括：BEP端口命名模块401、报文收发模块402、报文处理模块403、生成BEP端口模块404以及E-CID数据库模块405。

例如，可以设置的BEP端口生成方式包括802.1BR协议规定的普通的简单接口命名方式和本发明的详细接口命名方式。
报文收发模块402，配置为CB的级联口接收或者发送来自PE的Extended Port Create报文、Extended Port Create Reply报文和Extended Port  Delete报文。
报文处理模块403，配置为对报文收发模块402接收到的Extended Port Create、Extended Port Create Reply和Extended Port Delete报文进行处理。
生成BEP端口模块404，配置为根据BEP端口命名模块的配置方式生成BEP端口。
例如，生成带PE物理端口位置的BEP端口名，其格式包括但不限于如下形式：“BEP a/b/c/d/e”，其中，“a”代表PE-ID，即接口扩展设备的ID，“b”代表shelf-id，“c”代表slot-id，“d”代表sub-slot-id，“e”代表port-id；按简单接口命名方式生成不带PE物理端口位置的BEP端口，其格式包括但不限于如下格式：“BEP M”，M为CB上分配的一个随机值。
E-CID数据库模块405，配置为存储为生成的BEP端口分配的E-CID。
采用详细接口命名方式，在接收到PE发送的Extended Port Create消息后生成带有PE物理端口位置的BEP端口名(即上述的虚拟扩展端口的身份信息)并分配E-CID(即扩展通道标识)。如果要切换到简单接口命名方式，则删除现有的BEP端口名及E-CID，重新要求PE发送Extended Port Create消息后，按简单接口命名方式重新生成BEP端口名称及E-CID。该方法可为用户提供便于实际商用的带有物理位置的BEP端口命名方式，也提供了满足不同厂商对接兼容性要求的简单化BEP端口命名方式，实现了为不同的用户提供有区别的服务，可使用户体验较好。
