描述

显示有关已配置为触发警报的条件的信息。在 Junos 中,机箱警报与系统警报不同(使用 show system alarms 命令查看)。系统告警指示缺少救援配置或软件许可证(如果有效)。更多信息,请参阅 告警概述

选项

none

显示有关已配置为触发警报的条件的信息。

all-members

(仅限 MX 系列路由器)(选答)显示有关虚拟机箱配置的所有成员路由器的报警情况的信息。

interconnect-device name

(仅限 QFabric 系统)(选答)显示有关互连设备报警情况的信息。

local

(仅限 MX 系列路由器)(选答)显示有关本地虚拟机箱成员的报警情况的信息。

member member-id

(仅限 MX 系列路由器)(选答)显示有关虚拟机箱配置中指定成员的报警情况的信息。将变量替换 member-id 为 0 或 1。

node-device name

(仅限 QFabric 系统)(选答)显示有关节点设备报警情况的信息。

satellite [slot-id slot-id]

(仅限 Junos Fusion)(选答)显示 Junos Fusion 中指定卫星设备的报警情况信息,或者 Junos Fusion 中所有卫星设备的报警情况信息(如果未指定卫星设备)。

其他信息

机箱报警是预设的。您无法修改它们。

您无法清除机箱组件的告警。相反,您必须纠正警报的原因。当机箱报警 LED 亮起时,表示您正在采用我们不建议的方式运行路由器或交换机。

在路由器上,您可以通过按位于操作员接口上的报警切断按钮,手动使连接到报警继电器触点的外部设备静音。静音设备不会从显示屏上移除报警消息(如果路由器上存在)或熄灭报警 LED。此外,将外部设备静音后出现的新警报会重新激活外部设备。

注意:

MX10003路由器不支持操作员接口。

在 Junos OS 11.1 及更高版本中,风扇警报还会在 CLI 输出中显示风扇的插槽编号。

在 Junos OS 11.2 及更高版本中,EX8200 交换机上的命令输出会显示机箱中链路错误的详细位置 (Plane/FPC/PFE)。

在 Junos OS 10.2 及更高版本中,备用 SONET 时钟生成器 (SCG) 脱机或不存在,T Series 路由器上会显示告警。

您可能经常看到以下错误消息,其中仅显示错误代码,而不提供其他信息:

content_copy zoom_out_map
Apr 12 08:04:10 send: red alarm set, device FPC 6, reason FPC 6 Major Errors - Error code: 257
Apr 12 08:04:19 send: red alarm set, device FPC 1, reason FPC 1 Major Errors - Error code: 559

要了解 CM_ALARM 错误代码的含义,您需要首先识别 CM 警报代码的结构。CM_ALARM代码具有以下结构:

表 1:CM_ALARM代码结构

位:

错误类型:

1-31

主要 (1)

0

未成年人 (0)

根据上表,LSB(位 0)标识( Error Type 如果设置了位,则为主要告警,如果位未设置,则为次要告警)。其余位 (1 - 31) 标识实际错误代码。

以 T1600 上记录的以下错误代码为例:

content_copy zoom_out_map
Apr 12 08:04:10 send: red alarm set, device FPC 1, reason FPC 1 Major Errors - Error code: 559

首先,您必须将 559 转换为二进制;那就是 1000101111.本例中的 LSB 为 1,表示这是一个主要告警。删除 LSB 后,剩 100010111下 ,它等于十进制的 279。这是实际的错误代码,其含义可以从以下列表中找到:

根据上表, 279 错误代码对应于 CMALARM_NCHIP_DBUF_CRC_ERR;这意味着在这个特定 FPC 的 NCHIP 上看到了新的 CRC 错误,根据日志,该 FPC 是 FPC。

如果您不想将十进制转换为二进制,反之亦然,您可以使用以下快捷方式:

对于主要告警,其中 Actual Error Code = (Error Code - 1)/2Error Code 是您在日志消息中获得的代码。例如,如果收到以下日志:

content_copy zoom_out_map
    Apr 12 08:04:10 send: red alarm set, device FPC 6, reason FPC 6 Major Errors - Error code: 257

实际错误代码 = (257-1)/2 = 128。同样,对于轻微告警,实际错误代码 =(错误代码)/2

注意:

从 Junos OS 18.2R1 版开始,在 MX 系列路由器上, show chassis alarms 输出不显示 PFE 相关错误的错误代码。您可以使用以下命令查看导致警报的错误的更多详细信息:

  • show chassis errors active

显示机箱警报(MX2010、MX10008、MX10016 和 MX10004)

当配置的接口速度与支持的光纤速度之间存在差异时,可能会触发光纤配置不匹配告警。此告警表示指定 FPC 中安装的光学器件与接口上配置的速度不兼容。这可以通过以下输出进行观察:

如果主 LCMD 进程崩溃,如果备份 RE LCMD 连接稳定,系统将在一分钟后切换。在以下情况下,系统将不会切换:如果备份 RE LCMD 连接不稳定或当前主角色刚刚获得主角色。当主角色刚刚获得主要角色时,仅在 4 分钟后才会发生切换。

当 LCMD-CHASD IPC 通信在两到三分钟的短间隔内抖动三次时,会触发 LCM 对等连接不稳定告警。一旦 LCM 对等连接不稳定告警,连接状态将被监控两分钟。

从 Junos OS 演化版 21.2R1 开始,如果检测到 PEM 或 FET 故障,则会引发重大告警,并且识别出的 PSM 将根据命令中的 set chassis thermal-events fet-failure-check 预定义配置关断或发出告警。

对于 FET 故障检测和操作, show chassis alarm 如果 PSM 关断,输出将显示主要告警和信息。

例如,对于 show chassis 配置:

user@root> show chassis thermal-health-check 
                   { 
                      fet-failure-check; 
                      action-onfail auto-shutdown;
                   }

输出显示如下:
