怎麼解決CISCO模塊兼容性問題
怎麼解決CISCO模塊兼容性問題
Cisco設備只能用Cisco品牌的光模塊,其他品牌或雜牌的光模塊思科設備是絕對不支持的。如果你硬是插上別的光模塊,Cisco端口信息上就會顯示Unsupport或Unknown。日誌顯示以下情況中一種或幾種:
%PM_SCP-SP-3-TRANSCEIVER_UNSUPPORTED:Unsupported transceiver in LAN port */*
%PHY-4-CHECK_SUM_FAILED:SFP EEPROM data check sum failed for SFP interface Gi1/0/25
%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR:GBIC in port Gi1/0/25 has bad crc
%PM-4-ERR_DISABLE:gbic-invalid error detected on Gi1/0/25,putting Gi1/0/25 in err-disable state
Cisco SFP安全密鑰機制SFP安全密鑰機制通過防止非Cisco SFP的使用來保證質量和兼容性。每個SFP都使用非凡的軟件密鑰進行編碼,交換機在運行時對密鑰進行驗證,若SFP不包含合法的密鑰,那麼相應的端口關閉,在沒有插入Cisco提供的合法的SFP之前,該端口將不能發送或接收任何數據包。
那如何解決Cisco設備光模塊安全密鑰機制呢?進入端口配置模式:打上已下隱藏命令(不能按《tab》鍵):
service unsupported-transceiver
no errdisable detect cause gbic-invalid
speed nonegotiate
保存配置。然後插上光模塊,完成。現在Switch就不會去檢查GBIC的序號,而讓使用者可以先把第三方的GBIC或SFP插在機器上,讓網路先恢復運作。當然。並不鼓勵這樣做。如果非要如此,建議要熟記命令,否則用“?”但是無論如何也看見不到unsupported-transceiver出現在Command list裏面,
Cisco公司特別說明:用(config)#service unsupported-transceiver指令之後,設備會跳出以下的警告訊息。
Warning: When Cisco determines that a fault or defect can be traced to the use of third-party transceivers installed by a customer or reseller, then,at Ciscos discretion,Cisco may withhold support under warranty or a Cisco support program. In the course of providing support for a Cisco networking product Cisco may require that the end user install Cisco transceivers if Cisco determines that removing third-party parts will assist Cisco in diagnosing the cause of a support issue.
簡單的說,就是Cisco對於這些來路不明的GBIC不提供任何保證,網路要是不通,請用CISCO原裝產品
