串口连接新的Swtich上电后，先用串口和调测电脑连接，串口属性设置举例：如果敲了回车，电脑上没有打印输出，可以把switch下电上电，等switch启动后，打en命令，提示符变为NOS#，就可以做后续配置了。提示：打？，可以查看命令帮助。1.2 配置帐号和密码命令：username admin password 1 admin123 privilege 15说明：admin是帐号admin123是密码1.3 开启SSH服务命令：ip ssh server enable1.4 修改switch名字命令：hostname JiaoYuXueYuanBei_DATA说明：JiaoYuXueYuanBei_DATA是名字1.5 设置switch调测端口和VLAN1.5.1 设置端口举例：把第48口设置为电脑连接switch做调测用的端口JiaoYuXueYuanBei_DATA#configureJiaoYuXueYuanBei_DATA(conf)#interface tengigabitethernet 1/48JiaoYuXueYuanBei_DATA(conf-if-te-1/48)#no

switch_consoleJiaoYuXueYuanBei_DATA(conf-if-vl-255)#exit这样，我们电脑设置本地IP为192.168.222.0/24的某一个地址，就可以用网线连接Switch的48口，继续下面的配置了。1.6 设置switch之间的互通端口如果配置两台switch，通常光口switch连接CU业务相关的接口，如前向网络和后向网络；通常电口switch连接CU NCIR相关的接口，如NCIR OAM和NCIR内部管理网络。两台switch之间互通，可以用40G的同步线互联interface fortyGigE，也可以用六类网线+电模块互联interface TenGigabitEthernet。举例：用端口47互联两台switch，那么两台switch上都要配置好端口47，端口设置命令类似1.5.1。switch之间互通，实际上是两个switch上相同VLAN的互通，如设置VLAN 255互通，要用tag标签方式加上端口47。在switch 1上：JiaoYuXueYuanBei_DATA(conf)#interface vlan 255JiaoYuXueYuanBei_DATA(conf-if-vl-255)#ip address 192.168.222.254/24JiaoYuXueYuanBei_DATA(conf-if-vl-255)#untagged tengigabitethernet 1/48JiaoYuXueYuanBei_DATA(conf-if-vl-255)#tagged

(conf-if-vl-255)#exit2 配置CU相关的端口和VLAN在做CU端口配置前，需要具备一份Switch和Airframe的连线规划，和一份基站IP VALN规划。举例，某个试验网的连线规划如下，以10个compute node，支持10个基站为例：backhaul，fronthaul,和gNB OAM三个网络，分别有一个Vlan号，Vlan内部用不同IP地址区别不同基站。Internal_net和Internal_srv_net两个内部网络，是基站虚机内部通信网络（每个基站虚机的内部网络IP段相同），不同基站需要不一样的Vlan号。三个外部网络的规划如下，截取了switch的 IP地址和第一个基站的CU端IP资源举例： 内部网络VLAN举例：NCIR management：Vlan 81Internal net和Internal_srv_net：Vlan 3251 （每个基站虚机需要2个内部Vlan, 10个基站要20个内部Vlan）2.1 Airframe P4端口（physnet3）2.1.1 设置端口JiaoYuXueYuanBei_DATA#configureJiaoYuXueYuanBei_DATA(conf)#interface

haul方向，端口9/11/13/15链路聚合为40G，往backhaul以及OAM方向，配置步骤如下。3.1.1 设置Port-channel接口定义interface Port-channel 2 为链路聚合捆绑接口，往fronthaul：JiaoYuXueYuanBei_DATA#configureJiaoYuXueYuanBei_DATA(conf)#interface
