监控机箱群集接口
接口监控通过检查接口是处于运行状态还是故障状态来监控接口的状态。当一个或多个受监控接口发生故障时，冗余组将故障转移到群集中的另一个节点。有关更多信息，请参阅以下主题：
了解机箱群集冗余组接口监控
要使冗余组自动故障转移到另一个节点，必须监视其接口。配置冗余组时，您可以指定一组接口，冗余组要监控这些接口的状态（或“运行状况”），以确定接口是打开还是关闭。受监控接口可以是其任何冗余以太网接口的子接口。为要监控的冗余组配置接口时，需要为其赋予权重。
每个冗余组的阈值容差值最初设置为 255。当冗余组监控的接口不可用时，将从冗余组的阈值中减去其权重。当冗余组的阈值达到 0 时，它将故障转移到另一个节点。例如，如果冗余组 1 在节点 0 上是主冗余组，则在阈值交叉事件中，冗余组 1 在节点 1 上变为主冗余组。在这种情况下，冗余组 1 的冗余以太网接口的所有子接口都将开始处理流量。
要检查接口权重，请使用以下命令：
显示机箱群集信息
show chassis cluster interfaces
对于机箱群集中的 SRX 系列防火墙，我们不建议在冗余组 0 （RG0） 上配置数据平面模块，例如接口监控和 IP 监控。
在使用冗余组 0 手动故障转移时要谨慎和明智。冗余组 0 故障切换意味着路由引擎 （RE） 故障切换，在这种情况下，主节点上运行的所有进程都将被终止，然后在新的主路由引擎 （RE） 上生成。此故障切换可能导致状态丢失（如路由状态），并通过引入系统改动而降低性能。
发生冗余组故障切换的原因是冗余组的受监控接口的累积权重已将其阈值降至 0。当两个节点上的冗余组的受监控接口同时达到其阈值时，冗余组在节点 ID 较低的节点（在本例中为节点 0）上为主接口。
如果要抑制由于接口监控失败而发生的故障转移，请使用语
hold-down-interval句。如果冗余组 0 （RG0） 上发生故障切换，则 RG0 辅助节点上的接口监控将被禁用 30 秒。这样可以防止其他冗余组的故障切换以及 RG0 故障切换。
监控机箱群集的好处 冗余组接口
帮助确定特定冗余组设置的机箱群集中特定接口的状态。
如果接口关闭，允许将接口自动故障转移到另一个节点。

示例：配置机箱群集冗余组 接口监控
此示例说明如何指定由特定冗余组监视某个接口，以便自动故障转移到另一个节点。为要监控的接口分配权重 还演示了如何通过从每个节点配置两个接口并将其映射到冗余组来验证监控接口剩余阈值的过程。
要求
开始之前，请创建一个冗余组。请参阅 示例：配置机箱群集冗余组。
概述
要在监控接口关闭后检索剩余冗余组阈值，可以将系统配置为监控属于冗余组的接口的运行状况。当您为要监控的接口分配权重时，系统会监控该接口的可用性。如果物理接口发生故障，则将从相应冗余组的阈值中扣除权重。每个冗余组的阈值为 255。如果阈值达到 0，则会触发故障切换，即使冗余组处于手动故障切换模式且未启用该 preempt 选项也是如此。
在此示例中，您将通过从每个节点配置两个接口并将其映射到冗余组 1 （RG1）（每个接口具有不同的权重）来检查监控接口剩余阈值的进程。对节点 0 接口使用 130 和 140，对节点 1 接口使用 150 和 120。您可以为每个节点配置一个接口，并将这些接口映射到冗余组 2 （RG2），每个冗余组的默认权重为 255。

程序
分步过程
下面的示例要求您在各个配置层级中进行导航。有关作说明，请参阅《Junos OS CLI 用户指南》中的在配置模式下使用 CLI 编辑器。
要配置机箱群集接口监控，请执行以下作：
-
指定冗余以太网接口的数量。
[edit chassis cluster] user@host# set reth-count 3 -
为路由引擎故障切换属性设置冗余组 0，并设置 RG1 和 RG2（此例中所有接口都在一个冗余组中），以便为冗余以太网接口定义故障切换属性。
[edit chassis cluster] user@host# set redundancy-group 0 node 0 priority 254 user@host# set redundancy-group 0 node 1 priority 1 user@host# set redundancy-group 1 node 0 priority 200 user@host# set redundancy-group 1 node 1 priority 100 user@host# set redundancy-group 2 node 0 priority 200 user@host# set redundancy-group 2 node 1 priority 100 -
设置接口监控以监控接口的运行状况并触发冗余组故障切换。
不建议对 RG0 进行接口监控，因为它会导致控制平面在发生接口翻动时从一个节点切换到另一个节点。
[edit chassis cluster] user@host# set redundancy-group 1 interface-monitor ge-0/0/1 weight 130 user@host# set redundancy-group 1 interface-monitor ge-0/0/2 weight 140 user@host# set redundancy-group 1 interface-monitor ge-8/0/1 weight 150 user@host# set redundancy-group 1 interface-monitor ge-0/0/2 weight 120 user@host# set redundancy-group 2 interface-monitor ge-0/0/3 weight 255 user@host# set redundancy-group 2 interface-monitor ge-8/0/3 weight 255接口故障切换只会在权重达到零后发生。
-
设置冗余以太网 （reth） 接口并将其分配给一个区段。
[edit interfaces] user@host# set ge-0/0/1 gigether-options redundant-parent reth0 user@host# set ge-0/0/2 gigether-options redundant-parent reth1 user@host# set ge-0/0/3 gigether-options redundant-parent reth2 user@host# set ge-8/0/1 gigether-options redundant-parent reth0 user@host# set ge-8/0/2 gigether-options redundant-parent reth1 user@host# set ge-8/0/3 gigether-options redundant-parent reth2 user@host# set reth0 redundant-ether-options redundancy-group 1 user@host# set reth0 unit 0 family inet address 10.1.1.1/24 user@host# set reth1 redundant-ether-options redundancy-group 1 user@host# set reth1 unit 0 family inet address 10.2.2.2/24 user@host# set reth2 redundant-ether-options redundancy-group 2 user@host# set reth2 unit 0 family inet address 10.3.3.3/24

验证
以下各节将指导您完成验证接口状态和（在某些情况下）故障排除的过程。该过程将向您展示如何检查冗余组中每个接口的状态，在禁用后再次检查它们，并查找有关每个接口的详细信息，直到您遍历冗余组中的所有接口。
在此示例中，您可以通过从每个节点配置两个接口并将其映射到 RG1（每个接口具有不同的权重）来验证监控接口剩余阈值的过程。对节点 0 接口使用 130 和 140，对节点 1 接口使用 150 和 120。您可以为每个节点配置一个接口，并将接口映射到 RG2，每个接口的默认权重为 255。

示例输出确认，在节点 0 中，RG1 权重降低到 125（即 255 减去 130），因为监控接口 ge-0/0/1（权重为 130）下降。监控状态不正常，设备 LED 呈琥珀色，接口状态为 ge-0/0/1 关闭。
如果恢复接口 ge-0/0/1，则节点 0 中 RG1 的权重变为 255。相反，如果接口 ge-0/0/2 也被禁用，则节点 0 中 RG1 的权重将变为或更小（在本例中为 125 减去 140 = -15），并触发故障切换，如下一个验证部分所示。

意义
示例输出确认在节点 0 中，监控接口 ge-0/0/1 和 ge-0/0/2 已关闭。节点 0 上的 RG1 权重达到零值，在使用 show chassis cluster status 命令期间触发了 RG1 故障切换。
对于 RG2，为冗余以太网接口 2 （reth2） 设置了默认权重 255。当需要接口监控时，如果没有像 RG1 那样的备份链路，我们建议您使用默认权重。也就是说，如果禁用接口 ge-0/0/3，它会立即触发故障切换，因为权重变为 0（255 减去 225），如下一个验证部分所示。
禁用 ge-0/0/3 后验证接口状态
目的
验证接口 ge-0/0/3 是否已在节点 0 上禁用。
