Description

网络设备的管理方法、装置及系统
本申请要求于2019年10月21日提交的申请号为201911002749.9、发明名称为“网络设备的管理方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，特别涉及一种网络设备的管理方法、装置及系统。
背景技术
Restconf协议定义了一套网络设备的管理操作，该网络设备可以为交换机或路径器等。该管理操作包括增加网络设备的配置信息、删除网络设备的配置信息或修改网络设备的配置信息等至少一种操作。网络设备的配置信息保存在网络设备的配置数据库中，用户可以使用该套管理操作对网络设备的配置数据库进行修改，使网络设备的状态达到用户所期望的状态。
对配置数据库的修改包括在配置数据库中添加配置信息、删除配置数据库保存的配置信息或对配置数据库中的配置信息的内容进行修改。有时用户对网络设备的配置数据库进行修改后，发现修改有误，导致网络设备的状态发生错误，此时用户需要将配置数据库中保存的配置信息修改回去，以恢复出修改前配置数据库中保存的配置信息，从而实现恢复出网络设备的原状态。或者，有时在网络设备使用修改后的配置数据库运行一段时间后，用户需要恢复网络设备的原状态，此时用户也需要将配置数据库修改回去。
目前需要用户手动修改配置数据库，以对配置数据库进行恢复，手动修改往往需要较长时间，导致对配置数据库的恢复效率较低。
发明内容
本申请提供了一种网络设备的管理方法、装置及系统，以提高对配置数据加的恢复效率，所述技术方案如下：
第一方面，本申请提供了一种网络设备的管理方法，在所述方法中：网络设备接收管理设备发送的恢复报文，由于该恢复报文包括第一标识信息，第一标识信息用于标识已对网络设备的配置数据库执行的第一配置操作。网络设备从标识信息、操作对象与操作类型的对应关系中获取第一标识信息对应的操作对象和操作类型，该操作类型是第一配置操作的类型，该操作对象是第一配置操作所操作的对象。网络设备根据该操作对象和操作类型，将配置数据库由第一状态恢复成第二状态，第一状态是在执行第一配置操作之后配置数据库处于的状态，第二状态是在执行第一配置操作之前配置数据库处于的状态。这样在恢复配置数据库时，管理员只需要在管理设备输入第一标识信息，管理设备向网络设备发送包括第一标识信息的恢复报文，网络设备根据第一标识信息自动地恢复出第二状态的配置数据库，提高了恢复配置数据的效率。
在一种可能的实现方式中，网络设备接收管理设备发送的配置报文，配置报文包括第一标识信息、第一配置操作的操作类型和操作对象。网络设备将第一标识信息、该操作对象和该操作类型对应保存到标识信息、操作对象与操作类型的对应关系，以及，根据该操作对象对该配置数据库执行该操作类型对应的第一配置操作。由于网络设备保存第一标识信息、该操作对象和该操作类型之间的对应关系，从而可以在恢复配置数据库时，可以基 于保存的对应关系进行自动恢复。
在另一种可能的实现方式中，网络设备接收第一试运行请求，第一试运行请求包括第一标识信息，在第一标识信息标识的第一配置操作对应的第一试运行期间内，根据第一状态的配置数据库进行运行，第一试运行期间的起始时间是执行第一配置操作的时间，第一试运行期间的时间长度等于时长阈值。网络设备在第一试运行期间内接收到恢复报文时，从第一标识信息、操作对象与操作类型的对应关系中获取第一标识信息对应的操作类型和操作对象。由于网络设备在第一试运行期间内根据第一状态的配置数据库进行试运行，这样在第一试运行期间内可以检测出对配置数据库的修改是否有误，在有误的情况下及时请求恢复配置数据库，可以减轻网络设备对业务产生的影响。
在另一种可能的实现方式中，该配置报文还包括试运行标识，网络设备在该试运行标识的触发下，在第一配置操作对应的第一试运行期间内，根据第一状态的配置数据库进行运行，第一试运行期间的起始时间是执行第一配置操作的时间，第一试运行期间的时间长度等于时长阈值。网络设备在第一试运行期间内接收到恢复报文时，从第一标识信息、操作对象与操作类型的对应关系中获取第一标识信息对应的操作类型和操作对象。由于网络设备在第一试运行期间内根据第一状态的配置数据库进行试运行，这样在第一试运行期间内可以检测出对配置数据库的修改是否有误，在有误的情况下及时请求恢复配置数据库，可以减轻网络设备对业务产生的影响。
在另一种可能的实现方式中，网络设备接收第二试运行请求，第二试运行请求包括第二标识信息，第二标识信息用于标识第二配置操作，第二配置操作是网络设备已对配置数据库执行的操作。网络设备在第二配置操作对应的第二试运行期间内，根据第三状态的配置数据库进行运行，第二试运行期间的起始时间是执行第二配置操作的时间，第二试运行期间的时间长度等于时长阈值，第三状态是在执行第二配置操作后配置数据库处于的状态。网络设备在第二试运行期间内接收确认报文时，该确认报文包括第二标识信息，从标识信息、操作对象与操作类型的对应关系中删除包括第二标识信息的记录。这样在第二试运行期间内检测出对配置数据库的修改是正确的，则可以及时对配置数据库进行确认，避免网络设备在第二试运行期间结束时自动恢复配置数据库。
在另一种可能的实现方式中，网络设备接收第三试运行请求，第三试运行请求包括第三标识信息，第三标识信息用于标识第三配置操作，第三配置操作是网络设备已对配置数据库执行的操作。网络设备在第三配置操作对应的第三试运行期间内，根据第四状态的配置数据库进行运行，第三试运行期间的起始时间是执行第三配置操作的时间，第三试运行期间的时间长度等于时长阈值，第四状态是在执行第三配置操作后配置数据库处于的状态。网络设备在第三试运行期间内未接收到包括第三标识信息的报文时，则在第三试运行期间结束时根据第三配置操作对应的操作类型和操作对象，将该配置数据库由第五状态恢复成第四状态，第五状态是在执行第三配置操作之后配置数据库处于的状态。这样如果对配置数据库的修改有误，管理员可以不用对网络设备触发任何操作，只要在第三试运行期间结束时，网络设备自动地对配置数据库进行恢复，提高了恢复效率，还提高了用户体验。
在另一种可能的实现方式中，网络设备根据该操作对象获取恢复信息，恢复信息用于描述在对配置数据库中执行第一配置操作的过程配置数据库中发生变化的内容。网络设备根据该操作类型和该恢复信息，将配置数据库由第一状态恢复成第二状态。这样根据恢复信息将第一配置操作对配置数据库修改的内容进行恢复，而其他配置操作对配置数据库的修改仍可以保留。
在另一种可能的实现方式中，恢复报文为包括恢复标识信息和第一标识信息的报文，该恢复标识信息用于标识该报文的类型为恢复报文。
第二方面，本申请提供了一种网络设备的管理方法，在所述方法中，网络设备接收管理设备发送的恢复报文，恢复报文包括第一标识信息，第一标识信息用于标识第一配置信息，第一配置信息是在执行第一配置操作前网络设备的配置数据库中保存的配置信息，第一配置操作是网络设备已对配置数据库执行的操作。网络设备从标识信息与配置信息的对应关系中获取第一标识信息对应的第一配置信息。网络设备将配置数据库的内容更新为第一配置信息。这样在恢复出在执行第一配置操作前的配置数据库时，管理员只需要输入第一标识信息，管理设备向网络设备发送包括第一标识信息的恢复报文，网络设备根据第一标识信息自动地恢复出在执行第一配置操作前的配置数据库，提高了恢复配置数据的效率。
在一种可能的实现方式中，网络设备接收管理设备发送的配置报文，配置报文包括第一标识信息、第一配置操作的操作类型和操作对象。网络设备获取配置数据库中的内容，得到第一配置信息；将第一标识信息和第一配置信息对应保存在标识信息与配置信息的对应关系中，以及，根据该操作对象对配置数据库执行该操作类型应的第一配置操作。由于网络设备保存第一标识信息和第一配置信息之间的对应关系，从而可以在恢复配置数据库时，可以基于保存的对应关系进行自动恢复。

具体实施方式
参见图1，本申请实施例提供了一种网络设备的管理系统，该管理系统包括：
管理设备和网络设备，管理设备与网络设备之间可以建立有网络连接。
网络设备中包括配]置数据库，该配置数据库用于保存配置信息。网络设备根据该配置数据库中的配置信息进行运行。
可选的，网络设备可以为路由器或交换机等。该配置信息可以为网络流量的路由信息等，这样网络设备在接收到该网络流量时，根据配置数据库中保存的该网络流量的路由信息对该网络流量进行转发。
网络流量的路由信息包括网络流量的标识信息和下一跳信息。例如，参见下表1所示的配置数据库，假设该配置数据库包括两条配置信息，第一条配置信息是网络流量1的路由信息，包括网络流量1的标识信息“11”和下一跳信息“192.168.10.1”；第二条配置信息是网络流量2的路由信息，包括网络流量2的标识信息“12”和下一跳信息“192.168.10.2”。这样网络设备在接收到网络流量1时，根据第一条配置信息对网络流量1进行转发，在接收到网络流量2时，根据第二条配置信息对网络流量2进行转发。
表1
Figure PCTCN2020116938-appb-000001
管理设备可以使用一套配置操作对网络设备的配置数据库进行修改，然后网络设备根据修改后的配置数据库进行运行。由于修改前的配置数据库和修改后的配置数据库不同，这样网络设备根据修改前的配置数据库进行运行的运行状态和根据修改后的配置信息进行运行的运行状态也随之不同。
可选的，该套配置操作可以包括用于向配置数据库添加配置信息的添加操作、用于修改配置数据库中的配置信息的修改操作或用于删除配置数据库中的配置信息的删除操作等中的至少一个。
这样，管理设备可以在修改网络设备的配置数据库时，可以使用添加操作向网络设备的配置数据库中添加至少一条配置信息，或者，使用修改操作修改网络设备的配置数据库包括的至少一条配置信息，或者，使用删除操作删除网络设备的配置数据库中包括的至少一条配置信息。
可选的，管理设备可以在管理员的触发下对网络设备的配置数据库进行修改。通常管理员需要改变网络设备的运行状态时，管理员可以在管理设备中选择需要执行的配置操作。然后，管理设备对该网络设备的配置数据库执行该配置操作，以实现修改该网络设备的配置数据库。网络设备根据修改后的配置数据库进行运行，如此实现改变网络设备的运行状态。
例如，仍以上述网络流量为例，假设管理员需要调整网络设备转发该网络流量的转发 路径，则管理员可以在管理设备中配置该网络流量对应的新路由信息以及选择的配置操作为修改操作。然后，管理设备将网络设备的配置数据库保存的该网络流量的路由信息修改为该新路由信息，网络设备在接收到该网络流量时，根据配置数据库中保存的该新路由信息转发该网络流量，如此实现调整该网络流量的转发路径。
可选的，管理设备可以运行用于管理网设备的客户端，管理员可以通过该客户端修改网络设备的配置数据库。
管理员通过管理设备修改网络设备的配置数据库，该配置数据库中的部分内容会发生变化。网络设备根据修改后的配置数据库进行运行的运行状态可能与管理员需要的运行状态相同，也可能与管理员需要的运行状态不同。在网络设备的运行状态与管理员需要的运行状态相同时，表明管理员对配置数据库的修改正确，在网络设备的运行状态与管理员需要的运行状态不同时，表明管理员对网络设备的配置数据库的修改有误。例如，仍以上述网络流量为例，网络设备根据配置数据库中保存的该新路由信息转发该网络流量，在该网络流量的转发路径与管理员所期望的转发路径相同，表示对配置数据库的修改正确，在该网络流量的转发路径与管理员所期望的转发路径不同，表示对配置数据库的修改有误。
在对配置数据库的修改有误时，需要对配置数据库中发生变化的内容进行恢复。为了实现恢复配置数据库，可以在网络设备中定义试运行能力集，使网络设备具有试运行功能。所谓试运行功能是指当对网络设备的配置数据库执行完配置操作后，网络设备可以根据修改后的配置数据库运行一段时间。其中，如果在该段时间内发现对配置数据库的修改有误，管理设备可以请求网络设备对该配置数据库中发生变化的内容进行恢复。
这样，管理员在修改配置数据库时可能无法确定对配置数据库的修改是否正确，所以管理员在通过管理设备修改网络设备的配置数据库后，可以使网络设备根据修改后的配置数据库试运行一段时间。在试运行的该段时间内，如果管理员会发现网络设备的运行状态有误或管理设备会检测到网络设备的运行状态有误，则管理员可以通过管理设备触发网络设备对配置数据库中发生变化的内容进行恢复，或者，管理设备直接触发网络设备对配置数据库中发生变化的内容进行恢复。在试运行的该段时间内，如果管理员发现网络设备的运行状态正确或管理设备检测出网络设备的运行状态正确，则管理员可以通过管理设备对该配置数据库的修改进行确认，或者，管理设备直接对该配置数据库的修改进行确认。在对该配置数据库的修改进行确认后，网络设备在该段时间剩余的时间内以及在该段时间结束后，继续根据修改后的配置数据库运行。试运行的详细流程可以参见图2所示的实施例，在此先不详细说明。
管理员在修改配置数据库时能够确定对配置数据库的修改是正确的，则在修改该配置数据库后，网络设备根据修改后的配置数据库进行运行。在网络设备根据修改后的配置数据库运行一段时间后，管理员可能需要网络设备的运行状态恢复到在对该配置数据库进行修改前的运行状态，为了满足该需求，在网络设备中定义回退能力集，使网络设备具有回退功能。所谓回退功能是指在对网络设备的配置数据库执行完配置操作后，网络设备可以将修改后的配置数据库中的内容恢复到在执行该配置操作之前该配置数据库中保存的内容。
这样管理员可以通过管理设备触发网络设备将配置数据库的内容恢复到修改前的内容，以使网络设备的运行状态恢复到对该配置数据库进行修改前的运行状态。该过程的详细流程可以参见图8所示的实施例，在此先不详细说明。
参见图2，本申请实施例提供了一种网络设备的管理方法，该方法可以应用于图1所示的网络架构中。在方法中，可以使用网络设备的试运行功能对该配置数据库中发生变化的内容进行恢复。该方法包括：
步骤101：管理设备向网络设备发送配置报文，该配置报文包括试运行标识、第一标识信息、待执行的配置操作的操作类型和操作对象。
第一标识信息用于标识该配置操作，试运行标识用于指示网络设备在该配置操作对应的试运行期间内根据第一状态的配置数据库进行运行。第一状态是在对网络设备的配置数据库执行该配置操作后该配置数据库处于的状态。该试运行期间的起始时间为执行该配置操作的时间，该试运行期间的时间长度等于时长阈值。
该配置报文也可以不包括试运行标识，管理设备在发送配置报文时还向网络设备发送试运行请求，或者，在发送该配置报文之前向网络设备发送试运行请求，该试运行请求包括第一标识信息。该试运行请求用于请求网络设备在该配置操作对应的试运行期间内根据第一状态的配置数据库进行运行。
管理员可以向管理设备输入网络设备的标识、该配置操作的操作类型和操作对象，以及用于标识该配置操作的第一标识信息。然后，管理设备获取第一标识信息、该配置操作的操作类型和操作对象，生成包括试运行标识、第一标识信息、该配置操作的操作类型和操作对象的配置报文，根据该网络设备的标识信息，向网络设备发送配置报文；或者，生成包括第一标识信息、该配置操作的操作类型和操作对象的配置报文，以及生成包括第一标识信息的试运行请求，根据该网络设备的标识信息，向网络设备发送配置报文，以及发送试运行请求。

由于对配置数据库进行恢复时，管理员只需要输入第一标识信息和恢复标识信息，就可以触发网络设备自动地将配置数据库由第一状态恢复成第二状态，从而提高了恢复的效率。
在该配置操作对应的试运行期间内，如果管理员或管理设备发现网络设备根据处于第一状态的配置数据库进行运行的运行状态正确，则可以对网络设备的配置数据库进行确认，以避免在该配置操作的试运行期间结束后，网络设备自动将配置数据库由第一状态恢复成第二状态。详细实现过程包括如下106至107的操作。
步骤106：管理设备向网络设备发送确认报文，该确认报文包括第一标识信息。

步骤107：网络设备接收该确认报文，从标识信息、操作对象与操作类型的对应关系中删除包括第一标识信息的记录。
在本步骤中，网络设备接收到该确认报文，该确认报文包括确认标识信息和第一标识信息，在确认标识信息的触发下，停止对第一标识信息标识的配置操作进行计时，以及从标识信息、操作对象与操作类型的对应关系中删除包括第一标识信息的记录。

其中，网络设备可以从计时器与标识信息的对应关系中删除第一标识信息和第一标识信息对应的计时器，实现停止对第一标识信息标识的配置操作进行计时。

由于在该配置操作的试运行期间内网络设备没有接收包括第一标识信息的恢复报文，也没有接收到包括第一标识信息的确认报文，则在该配置操作的试运行期间结束时，在标识信息与计时器的对应关系中仍保存有第一标识信息对应的计时器，该计时器计时的时长达到该时长阈值，并且该计时器触发网络设备。此时网络设备在该计时器的触发下，根据该计时器对应的第一标识信息，从标识信息、操作类型与操作对象的对应关系中获取该配置操作对应的操作类型和操作对象，然后将配置数据库由第一状态恢复成第二状态。其中，在该计时器为倒计时器，在此时该计时器溢出并触发网络设备。

管理员向管理设备输入网络设备的标识、该配置操作的操作类型和操作对象，以及管理设备生成配置报文的详细实现过程可以参见上述步骤101中的相关内容，在此不再详细说明。
在本步骤中，在该配置报文中增加第一参数，设置第一参数的值等于第一标识信息，使得生成的配置报文包括第一标识信息。
例如，管理设备显示如图9所示的第四界面，第四界面包括用于选择操作类型的选择按钮1、用于输入第一标识信息的第一输入接口2、用于输入操作对象的第四输入接口5和用于输入网络设备的标识的第五输入接口6。选择按钮1可以为一个下拉按钮，选择按钮1中包括至少一个配置操作的操作类型，该至一个配置操作的操作类型包括post、creat和delete。
参见图9，假设管理员需要修改上述表1所示配置数据库中的第一条配置信息，第一条配置信息为网络流量1的路由信息，管理员需要将该路由信息中的下一跳信息由“11”修改为“192.168.10.3”。此时管理员选择待执行的配置操作的操作类型为修改操作post，在第一输入接口2中输入第一标识信息为abc，在第四输入接口5中输入操作对象，该操作对象包括待修改配置信息的标识“11”以及待修改配置信息的第一内容“192.168.10.3”，以及在第五输入接口6中输入网络设备的标识为IP1。
管理设备可以从图9所示的第四界面中读取该配置操作的操作类型post，第一标识信息abc，待修改配置信息的标识“11”，待修改配置信息的第一内容“192.168.10.3”，以及网络设备的标识为IP1。管理设备基于读取的信息生成的配置报文可以表示为：
post http://{IP1}{Port}:/restconf/systemInfo？conifig-id＝abc&timeout＝180
<routeInfo>
<Id info>11</Id info>(待修改配置信息的标识)
<Next hop>192.168.10.3</Next hop>(待修改配置信息的第一内容)
</routeInfo>
在配置报文中conifig-id为第一参数，网络设备再发送该配置报文。
步骤202：网络设备接收该配置报文，获取网络设备的配置数据库中的内容，得到第一配置信息，将第一标识信息和第一配置信息对应保存在标识信息与配置信息的对应关系中，以及根据该操作对象对配置数据库执行该操作类型对应的配置操作。
在本步骤中，网络设备接收该配置报文，对配置数据库中的内容进行复制得到该配置数据库中保存的第一配置信息，将第一标识信息和第一配置信息对应保存在标识信息与配置信息的对应关系中，以及根据该操作对象对配置数据库执行该操作类型对应的第一配置操作。
网络设备对该配置数据库执行该操作类型对应的第一配置操作的详细实现过程可以参见图2所示实施例中的步骤102中的相关内容。
接下来仍以步骤201中的例子对本步骤进行说明，网络设备接收如下配置报文：
post http://{IP1}{Port}:/restconf/systemInfo？conifig-id＝abc&timeout＝180
<routeInfo>
<Id info>11</Id info>
<Next hop>192.168.10.3</Next hop>
</routeInfo>
从该配置报文中提取操作类型为修改操作post，提取操作对象为待修改配置信息的标识“11”和第一内容为“192.168.10.3”，以及从该配置报文中提取第一参数conifig-id的值abc得到第一标识信息。对如表1所示的配置数据库进行复制，得到第一配置信息，将第一标识信息和第一配置信息对应保存到标识信息与配置信息的对应关系中。网络设备根据待修改配置信息的标识“11”，从如表1所示的配置数据库获取待修改配置信息，待修改配置信息包括待修改配置信息的标识“11”和第二内容“192.168.10.1”，然后，网络设备从上述表1所示的配置数据库中将待修改配置信息的第二内容“192.168.10.1”更新为第一内容“192.168.10.3”，得到的配置数据库如上述表9所示。
网络设备在对配置数据库执行完该配置操作后，网络设备根据该配置数据库进行运行。另外，如果管理员还继续需要对配置数据库执行配置操作，则管理员可以再向管理设备中输入网络设备的标识、该配置操作的操作类型和操作对象，以及用于标识该配置操作的标识信息，然后管理设备和网络设备再重新执行上述步骤201至202的操作。
有时管理员可能需要将网络设备的运行状态恢复到在执行某个配置操作之前的运行状态，此时需要将网络设备的配置数据库中保存的配置信息恢复到在执行该配置操作之前配置数据库保存的配置信息。其中，为了满足该需求，可以如下203至204的步骤来实现。
步骤203：管理设备向网络设备发送恢复报文，该恢复报文包括第一标识信息。
可选的，管理设备生成包括第一标识信息和回滚标识信息的报文，该回滚标识信息用于标识该报文的类型为恢复报文。
管理设备在生成报文时，可以设置该报文中的第一参数的值为第一标识信息，以及在该报文中添加回滚标识信息，如此实现生成包括第一标识信息和回滚标识信息的报文。
可选的，回滚标识信息为预设的信息，或为管理设备与网络设备事先约定的信息。
可选的，管理设备可以向管理员显示第五界面，管理员通过第五界面向管理设备输入 第一标识信息和回滚标识信息。
例如，参见图10所示的第五界面，第五界面包括用于输入第一标识信息的第一输入接口2、用于输入网络设备的标识的第四输入接口5、回滚标识信息“rollback”和用于供用户确认是否输入回滚标识信息的第八输入接口9。管理员确认输入回滚标识信息时，可以在第八输入接口9选择输入回滚标识信息(例如输入value，该value用于表示管理员选择输入回滚标识信息)，以及在第一输入接口2中输入第一标识信息abc、在第四输入接口5中输入网络设备的标识IP1。管理设备从第二界面中读取第一标识信息abc、回滚标识信息“rollback”和网络设备的标识IP1，基于读取的信息生成的恢复报文可以表示为：“http://{IP1}{Port}:/restconf/systemInfo？conifig-id＝abc&rollback”，向该网络设备发送该恢复报文。
步骤204：网络设备接收该恢复报文，从标识信息与配置信息的对应关系中获取第一标识信息对应的第一配置信息，将配置数据库的内容更新为第一配置信息。
在本步骤中，网络设备从该恢复报文中提取第一参数的值得到第一标识信息，以从该恢复报文中提取回滚标识信息，在该回滚标识信息的触发，从标识信息与配置信息的对应关系中获取第一标识信息对应的第一配置信息，将配置数据库的内容更新为第一配置信息。
例如，网络设备从该恢复报文“http://{IP1}{Port}:/restconf/systemInfo？conifig-id＝abc&rollback”中提取第一参数conifig-id的值abc得到第一标识信息，以从该恢复报文中提取回滚标识信息“rollback”，在该回滚标识信息“rollback”的触发下，从标识信息与配置信息的对应关系中获取第一标识信息abc对应的第一配置信息，第一标识信息abc对应的第一配置信息为表1所示的配置数据库中保存的配置信息，将表9所示的配置数据库的内容更新为第一配置信息，得到表1所示的配置数据库，从而实现恢复出在执行第一标识信息abc所标识的配置操作之前的配置数据库。
在本申请实施例中，网络设备接收管理设备发送的配置报文，该配置报文包括第一标识信息、待执行的配置操作的操作类型和操作对象；获取配置数据库中的内容，得到第一配置信息；将第一标识信息和第一配置信息对应保存在所述标识信息与配置信息的对应关系中，然后再根据该操作对象对配置数据库执行所述操作类型应的该配置操作。管理员需要恢复出执行该配置操作前的配置数据库时，管理员只需要向管理设备输入第一标识信息，管理设备向网络设备发送包括第一标识信息的恢复报文，这样网络设备根据恢复报文中的第一标识信息，从标识信息与配置信息的对应关系获取第一标识信息对应的第一配置信息，将配置数据库更新为第一配置信息，这样不需要编辑配置数据库中发生变化的内容，提高了恢复效率。
