本实施例中，第一设备端口和待测设备端可以为同一台设备上的端口，也可以为不同台设备的端口，例如，第一设备端口和待测设备端可以为同一交换机上的端口，也可以为不同台交换机上的端口。线速带宽是对单个端口而言的，可以理解为交换机端口每秒能转发的最大数据包的个数，以太网每个数据包最 小为64字节，将测试仪发送的vlan测试报文设置64字节的数据包，打满交换机端口，交换机的端口速率即达到该端口的线速带宽，交换机的端口速率也就是我们常说的10Gbps、40Gbps端口等。
在步骤120中，将vlan测试报文在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递。
第一设备端口的线速带宽和待测设备端口的线速带宽相同，且待测设备端口上预先配置有第一预设数量个虚拟端口，第一设备端口上也预先配置有第一预设数量个虚拟端口，通过第一预设数量个虚拟端口，在第一设备端口与待测设备端口之间进行vlan测试报文的传递。
第一设备端口和待测设备端口上的虚拟端口的数量相同，但是每个虚拟端口的标识有所区别，每个虚拟端口按照不同的配置，可以被划分在多个相同或者不同的vlan中。
如图4所示，例如：测试仪对应的线速带宽为10Gbps，待测设备端口和第一设备端口的线速带宽均为40Gbps，第一设备端口上的虚拟端口和待测设备端口上的虚拟端口的数量均为4个，第一设备端口上的虚拟端口为vlan113、vlan114、vlan115以及vlan116，待测设备端口上的虚拟端口为vlan114、vlan115、vlan116以及vlan117。测试仪发送的是vlan113测试报文，vlan113测试报文经过一个10Gbps端口，即图4所示的10G1端口，到达第一设备端口，第一设备端口在接收到vlan113测试报文之后，利用第一设备端口的vlan113虚拟端口通过第一设备端口与待测设备端口之间的连接将vlan113测试报文发送至待测设备端口，待测设备端口在接收到vlan113测试报文后翻译为vlan114测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan114测试报文发送至第一设备端口，再由第一设备端口将vlan114测试报文从第一设备端口发出。其中，交换芯片可以为以太网芯片(MAC芯片)，即交换机的转发芯片。
第一设备端口利用自身的vlan114虚拟端口，通过第一设备端口与待测设备端口之间的连接，将vlan114测试报文发送至待测设备端口，待测设备端口在接收到vlan114测试报文后翻译为vlan115测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan115测试报文发送至第一设备端口，再由第一设备端口将vlan115测试报文从第一设备端口发出。
在这种情况下，第一设备端口利用vlan115虚拟端口通过第一设备端口与 待测设备端口之间的连接将vlan115测试报文发送至待测设备端口，待测设备端口在接收到vlan115测试报文后翻译为vlan116测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan116测试报文发送至第一设备端口，再由第一设备端口将vlan116测试报文从第一设备端口发出。
第一设备端口利用vlan116虚拟端口通过第一设备端口与待测设备端口之间的连接将vlan116测试报文发送至待测设备端口，待测设备端口在接收到vlan116测试报文后翻译为vlan117测试报文。
待测设备端口将vlan116测试报文后翻译为vlan117测试报文之后，通过交换芯片检查vlan表项，将翻译得到的vlan117测试报文发送到被配置为vlan117的端口，即图4所示的10G2端口，由10G2端口将vlan117测试发送至测试仪。
在步骤130中，将经过第一预设数量次的传递之后接收到的所述vlan测试报文发送至所述测试仪，使所述测试仪检测所述vlan测试报文的丢包率，并根据所述vlan测试报文的丢包率确定待测设备端口在线速带宽条件下是否运行正常。
本实施例中以第一预设数量为4进行阐述，这里的传递次数可以理解为第一设备端口向待测设备端口发送vlan测试报文的次数。例如，在第一设备端口向待测设备端口发送4次vlan测试报文之后，得到的vlan测试报文为vlan116测试报文，待测设备端口在接收到vlan116测试报文后将vlan116测试报文翻译为vlan117测试报文，并通过交换芯片的vlan表项将vlan117测试报文发送至测试仪。
测试仪根据接收到的vlan117测试报文，检测vlan117测试报文的数据包的个数，并将开始发送的vlan113测试报文的数据包个数与vlan117测试报文的数据包的个数进行比较，根据比较结果判断vlan测试报文在传输过程中是否存在丢包，当vlan测试报文的丢包率为零时，确定待测设备端口在线速带宽条件下运行正常。当待测设备端口在线速带宽条件下运行正常时，待测设备端口有入方向的40Gbps线速带宽，即待测设备端口每发送一次vlan测试报文，可以累积待测设备端口入方向的10Gbps线速带宽。
可选地，待测设备端口、第一设备端口以及测试仪的端口均配置为中继模式(trunk模式)，使得每个端口可以支持多个vlan配置，并且可以配置不同 的本征vlan(Native Vlan)，保证数据不会被广播。而且高速率线速带宽设备的端口配置的vlan可以包含用于复制线速带宽时所需要的所有vlan，以防止数据被丢弃。其中，上述高速率线速带宽设备的端口可以为线速带宽为40Gbps、100Gbps或者线速带宽更大的端口，上述复制线速带宽可以理解为图4中第一设备端口与待测设备端口之间虚线表示的测试报文转发过程。
可选地，在通常情况下测试仪可以同时通过两个线速带宽相同的物理端口发送vlan测试报文至第一设备端口和第二设备端口，这里的第二设备端口为上述的待测设备端口，在这种情况下可以同时检测第一设备端口和第二设备端口在线速带宽条件下是否运行正常。本公开提供的多个实施例中以检测待测设备端口在线速带宽条件下是否运行正常为例进行阐述。
本发明实施例一，通过接收测试仪发送的、经第一设备端口转发的携带测试仪对应的线速带宽的vlan测试报文，其中测试仪对应的线速带宽小于待测设备端口的线速带宽；将vlan测试报文在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递后，接收到的测试报文发送至测试仪，使测试仪检测vlan测试报文的丢包率，并根据vlan测试报文的丢包率确定待测设备端口在线速带宽条件下是否运行正常，可以实现利用相关的测试设备检测高速率的设备端口在线速带宽条件下是否运行正常，不需要采购大速率的测试设备，节省了成本，实现资源的再次利用。
实施例二
如图5所示，为本发明实施例二提供的设备端口的检测方法，该方法可以应用于待测设备端口，可以包括步骤210-步骤240。
在步骤210中，接收测试仪发送的、经第一设备端口转发的携带测试仪对应的线速带宽的虚拟局域网vlan测试报文。
其中，测试仪对应的线速带宽小于待测设备端口的线速带宽。
其中，第一设备端口的线速带宽和待测设备端口的线速带宽相同，在接收vlan测试报文时的过程如下：
在测试仪发出的vlan测试报文依次经过测试仪与参考端口之间连接的第一线缆、所述参考端口与所述第一设备端口之间的vlan连接及第一设备端口与待测设备端口之间连接的第二线缆传输后，接收并获得测试仪发送的vlan测试报 文。
例如，参考端口可以与待测设备设置在同一单板上，参考端口可以与待测设备上的第一设备端口和待测设备端口连接，且参考端口的线速带宽大于等于测试仪对应的线速带宽。参考端口与测试仪之间通过第一线缆连接，参考端口与第一设备端口之间通过虚拟局域网连接，第一设备端口与待测设备端口通过第二线缆连接。
测试仪发送vlan测试报文，根据测试仪与参考端口之间的第一线缆将vlan测试报文发送至参考端口，根据参考端口与第一设备端口之间的虚拟局域网连接，将vlan测试报文发送至第一设备端口，根据第一设备端口与待测设备端口之间的第二线缆，将vlan测试报文发送至待测设备端口。
例如：测试仪对应的线速带宽为10Gbps，待测设备端口的线速带宽和第一设备端口的线速带宽均为40Gbps，参考端口的线速带宽为10Gbps，且参考端口可以与待测设备端口、第一设备端口设置在同一单板上，参考端口与第一设备端口通过虚拟局域网连接。在测试仪与参考端口连接时，测试仪与参考端口的线速带宽均为10Gbps，在这种情况下连接在测试仪与参考端口之间的第一线缆两侧的接头均与线速带宽10Gbps相匹配。第二线缆连接第一设备端口与待测设备端口，第二线缆两端的接头均与第一设备端口和待测设备端口的线速带宽40Gbps相匹配。vlan测试报文通过第一线缆、参考端口与第一设备端口之间的虚拟局域网以及第二线缆进入待测设备端口。在这种情况下，参考端口的线速带宽与测试仪的线速带宽相同，但参考端口的线速带宽与测试仪的线速带宽可以相同也可以不同，参考端口的线速带宽可以大于测试仪的线速带宽，参考端口的线速带宽也可以小于测试仪的线速带宽。
当参考端口的线速带宽与测试仪的线速带宽不相同时，例如，测试仪对应的线速带宽为10Gbps，待测设备端口的线速带宽和第一设备端口的线速带宽均为40Gbps，参考端口的线速带宽为40Gbps，且参考端口可以与待测设备端口、第一设备端口设置在同一单板上，参考端口与第一设备端口通过虚拟局域网连接。在测试仪与参考端口连接时，测试仪的线速带宽为10Gbps，参考端口的线速带宽为40Gbps，在这种情况下连接测试仪和参考端口的第一线缆可以采用一分四接头，即第一线缆的一侧为4个接头，每个接头对应10Gbps的线速带宽， 第一线缆的另一侧为一个接头，对应40Gbps的线速带宽。在测试仪一侧通过10Gbps的端口发出vlan测试报文，vlan测试报文到达参考端口之后，vlan测试报文所携带测试仪对应的线速带宽仍为10Gbps。第二线缆连接第一设备端口与待测设备端口，第二线缆两端的接头均与第一设备端口和待测设备端口的线速带宽40Gbps相匹配。vlan测试报文通过第一线缆、参考端口与第一设备端口之间的虚拟局域网以及第二线缆进入待测设备端口。其中，第一线缆4个接头一侧中的一个接头可以与测试仪连接，第一线缆一个接头一侧的40Gbps线速带宽接头与上述参考端口连接。
在步骤220中，将vlan测试报文在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递。
待测设备端口上预先配置有第一预设数量个虚拟端口，第一设备端口上也预先配置有第一预设数量个虚拟端口，通过第一预设数量个虚拟端口，在第一设备端口与待测设备端口之间进行vlan测试报文的传递。
可选地，当测试仪的端口种类为一种且待测设备端口的线速带宽是测试仪对应的线速带宽的整数倍时，第一预设数量为待测设备端口的线速带宽与测试仪对应的线速带宽的比值。
例如，待测设备端口的线速带宽为40Gbps，测试仪包括一种端口，且端口对应的线速带宽为10Gbps，在这种情况下待测设备端口的线速带宽是测试仪对应的线速带宽的4倍，第一预设数量为待测设备端口的线速带宽与测试仪对应的线速带宽的比值4。
当第一预设数量为4，测试仪与第一设备端口之间通过参考端口连接，vlan测试报文在待测设备端口与第一设备端口之间进行传递的流程如图6所示。
测试仪对应的线速带宽为10Gbps，待测设备端口和第一设备端口的线速带宽均为40Gbps，测试仪与第一设备端口之间通过参考端口连接，参考端口对应的线速带宽为40Gbps，参考端口与测试仪通过第一线缆连接，参考端口与第一设备端口通过虚拟局域网连接。第一设备端口上的虚拟端口和待测设备端口上的虚拟端口的数量均为4个。在这种情况下的第一线缆可以采用的是一分四接头，即第一线缆的一侧为4个接头，每个接头对应10Gbps的线速带宽，第一线缆的另一侧为一个接头，对应40Gbps的线速带宽。vlan测试报文在测试仪一侧通过测试仪10Gbps的端口发出，到达参考端口之后，vlan测试报文所携带测试 仪对应的线速带宽仍为10Gbps。
如图6所示，第一设备端口上的虚拟端口为vlan113、vlan114、vlan115以及vlan116，待测设备端口上的虚拟端口为vlan114、vlan115、vlan116以及vlan117。测试仪发送的是vlan113测试报文，vlan113测试报文通过第一线缆进入参考端口40G0，在这种情况下vlan113测试报文携带的测试仪对应的线速带宽仍为10Gbps。
根据参考端口与第一设备端口之间的虚拟局域网连接，将vlan113测试报文发送至第一设备端口，第一设备端口在接收到vlan113测试报文之后，利用vlan113虚拟端口通过第一设备端口与待测设备端口之间的第二线缆连接将vlan113测试报文发送至待测设备端口，待测设备端口在接收到vlan113测试报文后翻译为vlan114测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan114测试报文发送至第一设备端口，再由第一设备端口将vlan114测试报文从第一设备端口发出。
第一设备端口利用vlan114虚拟端口通过第一设备端口与待测设备端口之间的第二线缆连接将vlan114测试报文发送至待测设备端口，待测设备端口在接收到vlan114测试报文后翻译为vlan115测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan115测试报文发送至第一设备端口，再由第一设备端口将vlan115测试报文从第一设备端口发出。
在这种情况下，第一设备端口利用vlan115虚拟端口通过第一设备端口与待测设备端口之间的第二线缆连接将vlan115测试报文发送至待测设备端口，待测设备端口在接收到vlan115测试报文后翻译为vlan116测试报文，并且通过交换芯片检查vlan表项，将翻译得到的vlan116测试报文发送至第一设备端口，再由第一设备端口将vlan116测试报文从第一设备端口发出。
第一设备端口利用vlan116虚拟端口通过第一设备端口与待测设备端口之间的第二线缆连接将vlan116测试报文发送至待测设备端口，待测设备端口在接收到vlan116测试报文后翻译为vlan117测试报文。
待测设备端口将vlan116测试报文后翻译为vlan117测试报文之后，通过交换芯片检查vlan表项，将翻译得到的vlan117测试报文发送到参考端口中被配置为vlan117的端口，即图6所示的参考端口40G3，由参考端口40G3将vlan117测试报文发送至测试仪。
可选地，当测试仪的端口种类包括第一端口和线速带宽小于第一端口的线速带宽的第二端口，且待测设备端口的线速带宽是第一端口的线速带宽的非整数倍时，例如，待测设备端口的线速带宽为100Gbps，测试仪包括第一端口和第二端口，且第一端口对应的第一线速带宽为40Gbps，第二端口对应的第二线速带宽为10Gbps在这种情况下，待测设备端口的线速带宽是第一端口的第一线速带宽的2.5倍，在这种情况下在这种情况下，vlan测试报文的传递过程包括步骤2210-步骤2250，如图7所示。
在步骤2210中，获取待测设备端口的线速带宽与第一端口的线速带宽的比值在取整操作后的第一参考值。
可以利用软件计算待测设备端口的线速带宽与第一端口的第一线速带宽的比值，并对比值进行取整操作，即计算待测设备端口的线速带宽100Gbps与第一线速带宽40Gbps的比值，得到2.5，对2.5进行取整操作，获取第一参考值2。
在步骤2220中，接收测试仪发送的vlan测试报文，将vlan测试报文在预先配置的第一参考值个虚拟端口与第一设备端口之间进行传递。
待测设备端口接收到vlan测试报文后，通过预先配置的2个虚拟端口与第一设备端口进行vlan测试报文的传递，在传递完成后进行步骤2230。
在步骤2230中，获取待测设备端口的线速带宽与第一参考值和第一端口的第一线速带宽的乘积之差的第一差值。
可以利用软件计算第一参考值2与第一线速带宽40Gbps的乘积，将待测设备端口的线速带宽100Gbps与第一参考值2和第一线速带宽40Gbps的乘积80Gbps做差，获取第一差值20Gbps。
在步骤2240中，获取第一差值与第二端口的线速带宽的比值的第二参考值，其中第二参考值为整数，第一参考值与第二参考值的和为第一预设数量。
可以利用软件计算第一差值20Gbps与第二线速带宽10Gbps的比值，得到第二参考值2，其中第一参考值2与第二参考值2的和即为第一预设数量。第一参考值与第二参考值可以相等，也可以不等。
在步骤2250中，接收测试仪发送的vlan测试报文，将vlan测试报文在预先配置的第二参考值个虚拟端口与第一设备端口之间进行传递。
待测设备端口接收到vlan测试报文后，通过预先配置的2个虚拟端口与第 一设备端口进行vlan测试报文的传递，这里的2个虚拟端口与第二参考值相对应。
可选地，在待测设备端口的线速带宽是测试仪对应的线速带宽的非整数倍，例如：待测设备端口的线速带宽为100Gbps，测试仪对应的线速带宽为40Gbps时，待测设备上设置有10Gbps的端口，还可以将测试仪对应的线速带宽设置为10Gbps，实现测试仪与待测设备之间的vlan测试报文的传递，也可以采用一分四接头使得测试仪输出至待测设备的线速带宽为10Gbps，其中，第一线缆的一侧为4个接头，每个接头对应10Gbps的线速带宽，第一线缆的另一侧为一个接头，对应40Gbps的线速带宽，可以将第一线缆一个接头一侧与测试仪连接，将第一线缆4个接头一侧中的一个接头与参考端口连接，进而实现向测试设备端口发送测试报文进行端口测试。
其中，采用何种线缆，何种测试仪来实现vlan测试报文的传递，需要根据待测设备上的物理端口来确定。测试仪上可以包括一种端口，也可以包括两种或者多种端口。
在步骤230中，将经过第一预设数量次的传递之后接收到的vlan测试报文发送至测试仪，使测试仪检测vlan测试报文的丢包率，在vlan测试报文的丢包率为零时，确定待测设备端口在线速带宽条件下运行正常。
在第一设备端口与待测设备端口完成第一预设数量次的传递之后，待测试设备端口将接收到的vlan测试报文发送至测试仪，使得测试仪在获取待测试设备端口发送的vlan测试报文之后，统计vlan测试报文的数据包，将接收到的vlan测试报文的数据包与之前发送的vlan测试报文的数据包进行比较，当两者相等时，vlan测试报文不存在丢包，即丢包率为零时，确定待测设备端口在线速带宽条件下运行正常。
例如：测试仪接收到的是vlan117测试报文，根据接收到的vlan117测试报文，检测vlan117测试报文的数据包的个数，并将开始发送的vlan113测试报文的数据包个数与vlan117测试报文的数据包的个数进行比较，根据比较结果查看vlan测试报文在传输过程中是否存在丢包，当vlan测试报文的丢包率为零时，确定待测设备端口在线速带宽条件下运行正常。当待测设备端口在线速带宽条件下运行正常时，待测设备端口有入方向的40Gbps线速带宽，即待测设备端口每发送一次vlan测试报文后可以累积待测设备端口入方向的10Gbps 线速带宽。
在步骤240中，在vlan测试报文的丢包率不为零时，接收交换芯片发送的请求命令，并根据请求命令向所述交换芯片反馈待测设备端口对应的寄存器中的数据，使得交换芯片在判断出待测设备端口对应的寄存器中的数据处于正常范围时，确定待测设备端口在线速带宽条件下运行正常。
在vlan测试报文的丢包率不为零时，由于vlan测试报文在传递过程中经过多个端口，无法判断是不是待测设备端口的问题，需要待测设备端口接收交换芯片发送的请求命令，待测设备端口根据请求命令向交换芯片反馈待测设备端口对应的寄存器中的数据，使得交换芯片在接收到待测设备端口反馈的对应的寄存器中的数据后，查看寄存器中的数据是否处于正常范围内，在确定待测设备端口反馈的对应寄存器中的数据处于正常范围内时，确定待测设备端口在线速带宽条件下运行正常。
在待测设备端口通过虚拟端口接收到的vlan测试报文之后，将经过第一预设数量次的传递之后得到的vlan测试报文发送至测试仪，测试仪根据接收到的vlan测试报文来检测vlan测试报文在传递的过程中是否存在丢包的情况。在发送的vlan测试报文的数据包的个数与接收到的vlan测试报文的数据包的个数相等时，确定vlan测试报文不存在丢包，当发送的vlan测试报文的数据包的个数大于接收到的vlan测试报文的数据包的个数时，确定vlan测试报文存在丢包。其中，测试仪发送vlan测试报文的物理端口与接收vlan测试报文的物理端口属于不同的端口，但两个端口的类别相同。
其中，本发明实施例所提供的附图中虚线表示虚拟局域网连接，实线表示线缆连接。
本发明实施例二，通过接收测试仪发送的、经第一设备端口转发的携带测试仪对应的线速带宽的vlan测试报文，其中测试仪对应的线速带宽小于待测设备端口的线速带宽；将vlan测试报文在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递后接收到的测试报文发送至测试仪，使测试仪检测vlan测试报文的丢包率，并根据vlan测试报文的丢包率确定待测设备端口在线速带宽条件下是否运行正常，可以实现利用相关的测试设备检测高速率的设备端口在线速带宽条件下是否运行正常，不需要采购大速率的测试设备，节省了成本，实现资源的再次利用。
实施例三
如图8所示，为本发明实施例三提供的设备端口的检测方法，该方法可以应用于测试仪，步骤310-步骤330。
在步骤310中，经第一设备端口、向待测设备端口发送携带测试仪对应的线速带宽的虚拟局域网vlan测试报文，使得vlan测试报文在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递。
测试仪发送vlan测试报文，使得vlan测试报文通过第一设备端口传递至待测设备端口。例如，测试仪与参考端口通过线缆连接，利用线缆将vlan测试报文发送至参考端口，利用参考端口与第一设备端口之间的虚拟局域网连接，将vlan测试报文传递至第一设备端口，在利用第一设备端口与待测设备端口之间的线缆连接，将vlan测试报文传递至待测设备端口。
vlan测试报文到达待测设备端口之后，在待测设备端口上预先配置的第一预设数量个虚拟端口与第一设备端口之间进行传递。其中，测试仪发送的vlan测试报文是以64字节组成的数据包，在这种情况下的vlan测试报文可以体现测试仪的线速带宽。
在步骤320中，接收待测设备端口发送的经过第一预设数量次的传递之后得到的vlan测试报文，并检测vlan测试报文的丢包率。
测试仪接收待测设备端口发送的vlan测试报文，并根据接收到的vlan测试报文和发送的vlan测试报文来检测vlan测试报文在传递的过程中是否存在丢包的情况。当发送的vlan测试报文的数据包的个数与接收到的vlan测试报文的数据包的个数相等时，测试仪确定vlan测试报文不存在丢包，当发送的vlan测试报文的数据包的个数大于接收到的vlan测试报文的数据包的个数时，测试仪确定vlan测试报文存在丢包。
在步骤330中，根据所述vlan测试报文的丢包率，确定待测设备端口在线速带宽条件下是否运行正常。
当vlan测试报文在传递的过程中不存在丢包时，可以确定待测设备端口在线速带宽条件下运行正常，当vlan测试报文在传递的过程中存在丢包时，还需要利用交换芯片查看待测设备端口反馈的对应的寄存器中的数据，在待测设备端口向交换芯片反馈的对应寄存器中的数据处于正常范围内时，使得交换芯片 确定待测设备端口在线速带宽条件下运行正常。
本发明实施例三，通过测试仪向待测设备端口发送vlan测试报文，在测试仪接收到待测设备端口发送的经过第一预设数量次的传递之后得到的vlan测试报文之后，检测vlan测试报文的丢包率，在vlan测试报文的丢包率为零时，测试仪确定待测设备端口在线速带宽条件下运行正常，可以实现利用相关的测试设备检测高速率的设备端口在线速带宽条件下是否运行正常，不需要采购大速率的测试设备，节省了成本，实现资源的再次利用。
