Connectrix MDS：线卡无法启动，并显示错误“PORT-5-MODULE_BRINGUP_NOT_ALLOWED”

线卡插入先前填充的 MDS 控制器插槽时无法启动。

当新线卡与原始线卡的型号相同时，会看到以下 syslog 消息：

%PORT-5-MODULE_BRINGUP_NOT_ALLOWED: Not allowing module 8 to come up for reason: Speed group configuration is not supported. (0x4029018c)

如果新线卡与原始线卡的型号不同，则会看到以下系统日志消息：

%PORT-5-MODULE_BRINGUP_NOT_ALLOWED: Not allowing module 10 to come up for reason: Speed change not allowed (0x4029007f)

在这两种情况下，都会记录以下系统日志序列：

%VMM-2-VMM_SERVICE_ERR: VDC1: Service SAP Port manager (high) for slot 8 returned error 0x402901ac (Module insertion failed) in if_bind sequence

%IM-3-IM_RESP_ERROR: Component MTS_SAP_VMM opcode:MTS_OPC_IM_IF_VDC_BIND in vdc:1 returned error:Module insertion failed

%IM-3-IM_SEQ_ERROR: Error (Module insertion failed) while communicating with component MTS_SAP_VMM opcode:MTS_OPC_IM_IF_VDC_BIND (for:RID_MODULE: 8)

%MODULE-2-LCM_MODULE_INSERT_FAILURE_NEG_RSP: Slot-8 has failed to boot up because of service "Im SAP" due to module insertion failure

模块最终进入 故障 状态，如下图所示 show module command:
