如何判斷光模塊是否是華為認證的光模塊
1、華為定制光模塊的標簽上都有“HUAWEI”字樣的標簽,無該標簽的為非華為定制光模塊。
2、使用display transceiver命令查看光模塊信息,如果顯示廠商Vendor Name不是“HUAWEI”,那麽該光模塊不是華為定制光模塊。
3、查看是否存在非定制光模塊告警
用戶視圖下,執行命令terminal monitor命令開啟終端信息顯示功能;系統視圖下,執行命令undo transceiver phony-alarm-disable打開非定制光模塊告警開關。
如果光模塊是非定制光模塊,則從插入開始,按照階梯時間發送Trap告警。間隔分別為:10分鐘,1個小時,5個小時,最終達到24個小時告警壹次。最差的情況,24小時內會告警壹次。Trap信息如下(可通過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、對於某些造假、仿冒的光模塊,它們的信息往往是批量復制的,這些光模塊的序列號往往都壹樣。因此,可以使用display transceiver命令觀察批量光模塊信息,看它們的序列號(Manu. Serial Number)是否壹樣。如果壹樣,說明光模塊是仿冒的、非華為定制的。
