2、使用display transceiver命令查看光模块信息,如果显示厂商Vendor Name不是“HUAWEI”,那么该光模块不是HUAWEI定制光模块。
3、查看是否存在非定制光模块告警
用户视图下,实行命令terminal monitor命令开启终端信息显示功能;系统视图下,实行命令undo transceiver phony-alarm-disable打开非定制光模块告警开关。
如果光模块是非定制光模块,则从插入开始,按照阶梯时间发送Trap告警。间隔分别为:10分钟,1个小时,5个小时,最终达到24个小时告警一次。最差的情况,24小时内会告警一次。Trap信息如下(可通过display trapbuffer命令查看):
BASETRAP/1/ENTITYINVALID: OID[ 1.3.6.1.4.1.2011.5.25.129.2.1.9 ] Physical entity failed. (EntityPhysicalIndex=70107918, BaseTrapSeverity=6, BaseTrapProbableCause=136192, BaseTrapEventType=5, EntPhysicalContainedIn=69992457, EntPhysicalName="GigabitEthernet11/0/12", RelativeResource="", ReasonDescription="It has been observed that a transceiver has been installed that is not certified by Huawei Ethernet Switch. Huawei cannot ensure that it is completely adaptive and will not cause any adverse effects. If it is continued to be used, Huawei is not obligated to provide support to remedy defects or faults arising out of or resulting from installing and using of the non-certified transceiver.“)
或者
ENTITYTRAP/3/OPTICALINVALID:OID [1.3.6.1.4.1.2011.5.25.219.2.4.5] Optical Module is invalid.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName=\"[OCTET]\", EntityTrapFaultID=[136192])
4、对于某些造假、仿冒的光模块,它们的信息往往是批量复制的,这些光模块的序列号往往都一样。因此,可以使用display transceiver命令观察批量光模块信息,看它们的序列号(Manu. Serial Number)是否一样。如果一样,说明光模块是仿冒的、非HUAWEI定制的。
