今天在CISCO交換機上使用非CISCO標配的光模塊時提示如下錯誤信息:
%PM_SCP-SP-3-TRANSCEIVER_UNSUPPORTED光 Unsupported transceiver in LAN port */*
%PHY-4-CHECK_SUM_FAILED光 SFP EEPROM data check sum failed for SFP interface Gi1/0/25
%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR光 GBIC in port Gi1/0/25 has bad crc
%PM-4-ERR_DISABLE光 gbic-invalid error detected on Gi1/0/25, putting Gi1/0/25 in err-disable state
%PM_SCP-SP-3-TRANSCEIVER_UNSUPPORTED光 Unsupported transceiver in LAN port */*
%PHY-4-CHECK_SUM_FAILED光 SFP EEPROM data check sum failed for SFP interface Gi1/0/25
%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR光 GBIC in port Gi1/0/25 has bad crc
%PM-4-ERR_DISABLE光 gbic-invalid error detected on Gi1/0/25, putting Gi1/0/25 in err-disable state
原因：
查詢了一些CISCO相關資料才發現cisco設備是不允許使用非cisco標配的光模塊，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。

解決方法：
進入端口配置模式光
輸入下面的隱藏命令(不能按鍵)
第一條命令：
CISCO(config)#service unsupported-transceiver
輸入上面的命令後會輸出以下log：
Warning光 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 Cisco's 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.

第二條命令：
CISCO(config)#no errdisable detect cause gbic-invalid
CISCO(config)#no errdisable detect cause gbic-invalid
第三條命令：
CISCO(config)#speed nonegotiate
保存配置
然後插上光模塊
完成
CISCO(config)#speed nonegotiate
保存配置
然後插上光模塊
完成
破解後Cisco就不會去檢查 GBIC的序號，而讓使用者可以把第三方的 GBIC 或SFP 插在機器上，讓網絡先恢復運作。
