一、查看告警:
1、查看当前所有活动的硬件告警,包含发送和不发送trap的硬件告警。
[~HUAWEI] display alarm all/hardware all=hardware
2、查看当前所有能发trap的活动告警,包括硬件告警和业务告警。
[~HUAWEI] display alarm active
3、查看所有历史active告警信息(active告警恢复后显示)
[~HUAWEI] display alarm history
总结:
all/hardware 硬件告警:包含发 和 不发trap告警
active 硬件和业务告警:一定发trap告警,all(hardware)和active有重复硬件告警但又不全包含
history active 和 history是对应的,active告警恢复后显示。
二、清除告警:
NE路由器当板卡有红灯告警时,说明设备已经产生告警,但是经常遇到清除告警后仍然显示红灯的情况,大多是因为没有正确的清除告警。
1、清除 all/hardware 硬件告警
<HUAWEI> clear alarm hardware all send-trap
2、清除 active 硬件和业务告警
[~HUAWEI] alarm
[~HUAWEI-alarm] clear alarm active all
三、配置发送给网管的trap告警类型
[~HUAWEI] snmp-agent trap type dc-trap/base-trap/entity-trap
区别:dc-trap 对应 HUAWEI-DC-TRAP-MIB
base-trap 对应 HUAWEI-BASE-TRAP-MIB
entity-trap 对应 HUAWEI-ENTITY-TRAP-MIB .
(1)trap类型区别:
dc-trap 提供的告警信息种类和数量较少,V8版本基本取消,不推荐,当遇到收到告警类型少时注意确认
base-trap 提供的告警信息详细具体。
entity-trap 比base-trap更加丰富。
以接口UP/DOWN为例对比base和entity trap:
base-trap:
接口UP:无 hwPortPhysicalUp
接口DOWN:Nov 25 2022 13:03:31+08:00 HUAWEI %%01PIC/1/hwPortPhysicalDown(t):CID=0x80fc04b9-OID=1.3.6.1.4.1.2011.5.25.129.2.5.1;The status of the physical interface is Down. (BaseTrapSeverity=3, BaseTrapProbableCause=74752,BaseTrapEventType=5,EntityPhysicalIndex=16847116,EntPhysicalName=GigabitEthernet1/0/11, ReasonDescription=The status of the physical interface is Down.)
entity-trap:
接口UP:Nov 25 2022 13:17:03+08:00 HUAWEI %%01PIC/1/hwPortUp(t):CID=0x80fc04b9 OID=1.3.6.1.4.1.2011.5.25.219.2.12.2;The status of the physical interface is Up.(EntityPhysicalIndex=16847116, EntPhysicalIndex=16847116, EntPhysicalName=GigabitEthernet1/0/11, EntityTrapFaultID=144384, ReasonDescription=The status of the physical interface is Up.)
接口DOWN:Nov 25 2022 13:18:29+08:00 HUAWEI %%01PIC/1/hwPortDown(t):CID=0x80fc04b9-OID=1.3.6.1.4.1.2011.5.25.219.2.12.1;The status of the physical interface is Down.(EntityPhysicalIndex=16847116, EntPhysicalIndex=16847116, EntPhysicalName=GigabitEthernet1/0/11, EntityTrapFaultID=144384, ReasonDescription=The status of the physical interface is Down.)
(2)查看设备trap类型支持情况
①通过命令 snmp-agent trap type 确认支持情况
②不支持配置的,诊断视图下命令确认trap类型:
[HUAWEI-diagnose]display configuration data running table-data SysTrapInfoCfg
Field(0) Field(1) Field(2) Field(3) Field(4) Field(5) Field(6)
validflag index sysTrapType iid lifeCycle visibleVR visibleLR
0xffffffff 0x1 0x1 0x1 0x0 0xffffffff 0xffffffff
sysTrapType值:1表示base-trap,2表示dc-trap,4表示entity-trap
2、模拟告警的产生和清除
[~HUAWEI-diagnose] simulate alarm-name AIS alarm-state start/end
3、查看告警name和告警ID
[~HUAWEI] display alarm information name AIS
4、过滤告警 ID/模块,告警ID不是OID
[~HUAWEI] info-center filter-id ********
模拟、查看、过滤告警的综合应用举例
文档以模块举例,这里以告警ID来举例,需要注意过滤的告警ID不是OID。
①模拟、查看告警
[~HUAWEI-diagnose] simulate alarm-name AIS alarm-state start
[~HUAWEI-diagnose] simulate alarm-name AIS alarm-state end
[~HUAWEI] display trapbuffer
Nov 25 2022 09:05:07+08:00 HUAWEI %%01EOAM-Y1731/4/hwY1731AisDefectAlarmRecovery(t):CID=0x80e70446-OID=1.3.6.1.4.1.2011.5.25.136.1.6.31;MEP exits AIS defect condition. (MdIndex=0, MaIndex=0, MdName=SimulateStringData, MaName=SimulateStringData, MepID=0)
Nov 25 2022 09:05:01+08:00 HUAWEI %%01EOAM-Y1731/4/hwY1731AisDefectAlarm(t):CID=0x80e70446-OID=1.3.6.1.4.1.2011.5.25.136.1.6.30;MEP enters AIS defect condition. (MdIndex=0, MaIndex=0, MdName=SimulateStringData, MaName=SimulateStringData, MepID=0)
②查看告警ID
[~HUAWEI] display trapbuffer]display alarm information name AIS
------------------------------------------------------------------------------------------
Feature : EOAM-Y1731
AlarmName : AIS
AlarmId : 0x9AC2020 //注意这里是16进制,过滤时需要转换为十进制,0x9AC2020->162275360
Severity : Warning
Cause suppress time : 0
Clear suppress time : 0
③通过告警ID过滤
[~HUAWEI] info-center filter-id 162275360
[~HUAWEI] display trapbuffer 确认看不到AIS最新的告警信息
