CMTS配置命令详解.doc

同维电子有限公司测试部拟制人时间梅术堂2013年10月23日 CMTS配置方法摘要：CMTS(Cable Modem Terminal Systems)，CMTS是管理控制Cable Modem的设备，其配置可通过Consol接口或以太网接口完成。其配置内容主要有：下行频率、下行调制方式、下行电平、上行频率、上行调制方式、上行电平、CMTS的IP地址等关键字：CMTS缩略语：CMTS(Cable Modem Terminal Systems)一、配置文件配置；（1）、新的CMTS导入配置1、 用串口连接CMTS的COM口，波特率为96002、 CMTS的interface GigabitEthernet0/1配置IP； UBR7246VXR#configure /进入配置模式UBR7246VXR(config)#interface
