Technical field
本发明涉及网络管理领域，特别涉及一种管理网络设备端口状态的方法、 系统及中转设备。 背景技术 The present invention relates to the field of network management, and in particular, to a method, a system, and a transit device for managing a port state of a network device. Background technique
在当前的网络应用中， 用户对网络可靠性的要求越来越高， 特别是在一 些重点的业务入口或接入点上， 例如企业的 interne t接入点， 银行的数据库 服务器等， 用户希望保证网络的不间断运行， 在这种业务点上如果只使用一 台网络设备， 无论其可靠性多高， 系统都必然要承受因单点故障而导致网络 中断的风险。 In current network applications, users have higher and higher requirements for network reliability, especially at some key service portals or access points, such as the enterprise's intern t access point, the bank's database server, etc. To ensure the uninterrupted operation of the network, if only one network device is used at this service point, no matter how high the reliability, the system must bear the risk of network interruption due to a single point of failure.
釆用双机热备组网方案可以很好解决当前网络应用中单台网络设备可靠 性不高的问题。 该方案釆用两条动态虚拟链路， 一条链路是主用链路， 另一 条链路是备用链路， 当主用链路出现故障时， 系统会将业务切换到备用链路 上进行正常传输， 从而保障了业务传输的不间断性。 图 1是现有技术提供的 双机热备方案的组网示意图。 正常情况下， 业务通过主用链路路由器 A→防 火墙 A →路由器 C进行传输， 当主用链路出现故障时， 业务被切换到备用链 路路由器8→防火墙 B→路由器 D进行传输， 从而保障了终端业务传输的不 间断性。 The dual-system hot backup networking solution can solve the problem of low reliability of single network equipment in current network applications. The solution uses two dynamic virtual links. One link is the primary link and the other link is the standby link. When the primary link fails, the system switches the service to the standby link for normal transmission. Thus, the uninterrupted nature of service transmission is guaranteed. FIG. 1 is a schematic diagram of networking of a dual-system hot standby solution provided by the prior art. Under normal circumstances, the service is transmitted through the primary link router A → firewall A → router C. When the primary link fails, the service is switched to the backup link router 8 → firewall B → router D for transmission, thus ensuring Uninterrupted transmission of terminal services.
如果防火墙 A和路由器 C相连的端口发生故障， 从终端 A到终端 B的业 务可以通过链路路由器 C →路由器 D→防火墙 B→路由器 B 进行传输。 从
终端 B返回给终端 A的业务可能会通过链路路由器 A→ 防火墙 A→路由器 C 进行传输， 由于防火墙 A和路由器 C相连的端口发生故障， 防火墙 A和路由 器 C之间的链路中断， 从终端 B返回给终端 A的业务无法通过。 此时， 由于 路由器 A并不能感知防火墙 A和路由器 C之间的端口状态， 无法进行路由切 换， 导致终端业务传输中断。 当前组网情况日益复杂的情况下， 在釆用双机热备组网方案时， 如果中 转设备的端口出现故障， 会导致与中转设备相连的上下行设备无法将终端业 务切换到备用链路， 从而导致终端业务传输中断。 发明内容 If the port connected to firewall A and router C fails, the service from terminal A to terminal B can be transmitted through link router C → router D → firewall B → router B. From The service that terminal B returns to terminal A may be transmitted through link router A→firewall A→router C. Because the port connected to firewall A and router C fails, the link between firewall A and router C is interrupted. B The service returned to terminal A cannot pass. At this time, because the router A cannot sense the port status between the firewall A and the router C, the route switching cannot be performed, and the terminal service transmission is interrupted. If the current networking situation is becoming more and more complex, when the dual-system hot backup networking solution is adopted, if the port of the transit device fails, the upstream and downstream devices connected to the transit device cannot switch the terminal service to the standby link. As a result, the terminal service transmission is interrupted. Summary of the invention

为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本发 明实施方式作进一步地详细描述。 显然， 所描述的实施例仅仅是本发明一部
分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术 人员在没有作出创造性劳动前提下所获得的所有其他实施例， 都属于本发明 保护的范围。 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiment is only one part of the invention. The embodiments are divided into embodiments, not all. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
本发明实施例提供了一种管理网络设备端口状态的方法， 包括： 中转设 测到预设逻辑组内任意端口的工作状态为故障状态时， 将预设逻辑组内其它 端口的工作状态都设置为故障状态， 使所述中转设备的上下行设备在检测到 中转设备端口为故障状态时， 将终端业务切换到备用链路， 从而可以保证终 端业务正常传输。 如图 2所示， 本发明实施例的具体步骤为： 个逻辑组。 The embodiment of the invention provides a method for managing the state of a port of a network device, including: setting, when the working state of any port in the preset logical group is a fault state, setting the working state of other ports in the preset logical group In the fault state, when the uplink and downlink device of the transit device detects that the transit device port is in a fault state, the terminal service is switched to the standby link, so that the terminal service can be normally transmitted. As shown in FIG. 2, the specific steps of the embodiment of the present invention are: logical groups.
按照终端业务需求在中转设备建立一个端口号和逻辑组号关联关系的列 表， 为与中转设备相连的上下行设备的多个端口分配同一个逻辑组号。 例如, 设备中的与中转设备的下行设备相连的端口 B进行传输， 此时可以将端口 A 和端口 B分配给同一逻辑组。 又如， 终端业务经过中转设备中的与中转设备 的上行设备相连的端口 C和端口 D , 以及中转设备中的与中转设备的下行设 备相连的端口 E和端口 F进行传输， 此时， 可以将端口 C、 D、 E、 F分配给同 一逻辑组。 中转设备的端口和逻辑组的关系并不局限于上述实例， 实际应用 中， 可以按照终端业务的需求进行相应设置。 Set a port number and logical group number association relationship on the transit device according to the terminal service requirements, and assign the same logical group number to multiple ports of the uplink and downlink devices connected to the transit device. For example, port B in the device connected to the downstream device of the transit device is transmitted. In this case, port A and port B can be assigned to the same logical group. For example, the terminal service is transmitted through the port C and the port D of the transit device connected to the uplink device of the transit device, and the port E and the port F connected to the downlink device of the transit device in the transit device. Ports C, D, E, and F are assigned to the same logical group. The relationship between the port and the logical group of the transit device is not limited to the above example. In actual applications, the corresponding settings can be made according to the requirements of the terminal service.
步骤 1 02 : 中转设备检测预设逻辑组内端口的工作状态， 当中转设备检 测到预设逻辑组中的任意端口出现故障时， 将预设逻辑组中其它端口都设置 为故障 （Down )状态。 Step 1 02: The transit device detects the working status of the port in the preset logical group. When the transit device detects that any port in the preset logical group is faulty, the other ports in the preset logical group are set to the Down state. .
步骤 1 03 : 当中转设备的上行设备和下行设备检测到中转设备的端口出 现故障时， 将终端业务切换到备用链路。 Step 1 03: When the uplink device and the downlink device of the transit device detect that the port of the transit device is faulty, the terminal service is switched to the standby link.
由于在步骤 1 02中， 中转设备的逻辑组内的端口状态都为故障状态， 端 口的状态变化使中转设备的上（下）行链路出现故障， 此时， 与中转设备相
连的上（下）行设备可以通过端口的故障状态， 感知到端口出现故障， 并同 时将终端业务切换到备用链路。 Since in step 102, the state of the port in the logical group of the transit device is a fault state, the state change of the port causes the uplink (lower) link of the transit device to be faulty, and at this time, the transit device is The connected upper (lower) row device can detect the port failure through the fault state of the port and simultaneously switch the terminal service to the standby link.
此外， 当中转设备检测到预设逻辑组中的所有端口工作正常时， 将预设 逻辑组中所有端口都设置为正常状态。 此时， 与中转设备相连的上 （下）行 设备可以通过端口的正常状态， 感知到端口工作正常， 并同时将业务切换回 主用链路。 In addition, when the transit device detects that all ports in the preset logical group are working properly, all ports in the preset logical group are set to the normal state. At this time, the upper (lower) row device connected to the transit device can pass the normal state of the port, and sense that the port works normally and simultaneously switch the service back to the active link.
下面将结合以下场景对本实施例进行详细的描述： The present embodiment will be described in detail below in conjunction with the following scenarios:
第一种场景的组网示意图仍然基于图 1所示的组网而实现。 图中， 防火 墙 A和 B为中转设备（中转设备也可以是路由器、 服务器或交换机） ， 主用 链路是路由器 A→防火墙 A→路由器 C , 备用链路是路由器 B→防火墙 B 路 由器 D , 正常情况下， 业务通过主用链路进行传输。 按照终端业务的需求将 防火墙 A中的与路由器 A和路由器 C相连的多个端口绑定到一个逻辑组中， 将防火墙 B中的与路由器 B和路由器!)相连的多个端口绑定到一个逻辑组中。 初始状态下， 防火墙 A和防火墙 B的逻辑组中的多个端口是 UP (正常）状态。 防火墙 A检测自身内部存储的逻辑组中的端口故障状态， 当检测到逻辑组中 的任意端口工作状态是故障状态时，将逻辑组中的其它端口设置为故障状态。 此时， 路由器 A和路由器 C都能感知到端口故障， 并进行路由切换， 将业务 从主用链路切换到备用链路上； 当防火墙 A检测到逻辑组内的所有端口的工 作状态是正常状态时， 将逻辑组内的端口状态都设置 UP状态。 此时， 路由器 A 和路由器 C都能感知到端口正常， 并进行路由切换， 将终端业务从备用链 路切换到主用链路上， 从而保证终端业务不间断运行。 The networking diagram of the first scenario is still implemented based on the networking shown in FIG. 1. In the figure, firewalls A and B are transit devices (transit devices can also be routers, servers or switches), the primary link is router A → firewall A → router C, and the standby link is router B → firewall B router D, normal In this case, the traffic is transmitted over the primary link. Bind multiple ports connected to Router A and Router C in firewall A to a logical group according to the requirements of the terminal service, and bind multiple ports connected to Router B and Router! in Firewall B to one. In the logical group. In the initial state, multiple ports in the logical group of firewall A and firewall B are in the UP (normal) state. Firewall A detects the port fault status in the logical group stored in its own. When it detects that any port in the logical group is in the fault state, the other ports in the logical group are set to the fault state. At this point, both Router A and Router C can detect port faults and perform route switching to switch services from the primary link to the standby link. When firewall A detects that all ports in the logical group are working properly. In the status, the port status in the logical group is set to the UP state. At this time, both Router A and Router C can detect that the port is normal and perform route switching to switch the terminal service from the standby link to the active link to ensure uninterrupted operation of the terminal service.
第二种场景的组网示意图如 3所示。 图 3中， 网络 A和网络 B之间通过 路由器 A连接， 路由器 A通过两条链路连接到防火墙 A (防火墙 A为中转设 备） 。 正常情况下， 终端业务经过路由器 A发送给防火墙 A , 防火墙对业务 进行过滤后， 再发送给路由器 A , 路由器 A将过滤的终端业务发送给网络中 的终端， 这种业务传输的路径称为高优先级链路（也可称为主用链路） 。 低 优先级链路（也可称为备用链路）是指网络间直接通过路由器 A传输业务。
将防火墙 A上的与路由器 A相连的多个端口绑定到同一逻辑组。 当防火墙 A 检测到逻辑组内的任意端口的工作状态为故障状态时， 将逻辑组内的其它端 口都设置为故障状态。 此时， 路由器 A检测到防火墙 A的端口故障时， 将终 端业务切换到低优先级链路上； 当防火墙 A检测到逻辑组内的所有端口工作 正常时， 将逻辑组内的所有端口都设置为正常状态， 此时路由器 A检测到防 火墙 A的所有端口正常时， 将终端业务切换到高优先级链路上， 从而保证终 端业务的不间断运行。 The networking diagram of the second scenario is shown in 3. In Figure 3, network A and network B are connected by router A, and router A is connected to firewall A through two links (firewall A is a transit device). Normally, the terminal service is sent to the firewall A through the router A. After filtering the service, the firewall sends the service to the router A. The router A sends the filtered terminal service to the terminal in the network. The path of the service transmission is called high. Priority link (also known as the primary link). A low-priority link (also referred to as a backup link) refers to the transmission of traffic between routers directly through router A. Bind multiple ports on Router A that are connected to Router A to the same logical group. When firewall A detects that the working status of any port in the logical group is faulty, the other ports in the logical group are set to the fault state.
