如果使用非cisco模块插入cisco交换机,会提示
%PM-4-ERR_DISABLE:gbic-invalid error detected on Gi1/0/25,putting Gi1/0/25 in err-disable state
Cisco思科 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。
可以通过隐藏命令,无法从?来找到。
service unsupported-transceiver
no errdisable detect cause gbic-invalid
speed nonegotiate
copy running-config startup-config
然后需对交换机重启后才能生效。
Cisco公司特别说明:用(config)#service unsupported-transceiver指令之后,设备会跳出以下的警告讯息。
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.
