今天在CISCO交换机上使用非CISCO标配的光模块时提示如下错误信息:
%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:
查询了一些CISCO相关资料才发现cisco设备是不允许使用非cisco标配的光模块,Cisco SFP 安全密钥机制 SFP 安全密钥机制通过防止非 Cisco SFP 的使用来保证质量和兼容性。每个 SFP 都使用非凡的软件密钥进行编码,交换机在运行时对密钥进行验证,若 SFP 不包含合法的密钥,那么相应的端口关闭,在没有插入 Cisco 提供的合法的 SFP 之前,该端口将不能发送或接收任何数据包。

解决方法:
进入端口配置模式光
输入下面的隐藏命令(不能按键)
第一条命令:
CISCO(config)#service unsupported-transceiver
输入上面的命令后会输出以下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.

第二条命令:
CISCO(config)#no errdisable detect cause gbic-invalid
CISCO(config)#no errdisable detect cause gbic-invalid
第三条命令:
CISCO(config)#speed nonegotiate
保存配置
然后插上光模块
完成
CISCO(config)#speed nonegotiate
保存配置
然后插上光模块
完成
破解后Cisco就不会去检查 GBIC的序号,而让使用者可以把第三方的 GBIC 或SFP 插在机器上,让网络先恢复运作。
