弱弱问一个问题，如何查看抓包目的端口？

Tobenone

请问，在2952交换机上设置了 monitor ，分别设置  destination interface  和 source interface ，一段时间后忘记设置的destination interface，用sh monitor 命令 只能看到 mointor session 和 source interface ，看不到 destination interface ？请问该用哪条命令可以看到 destination interface ， 谢谢！！

看不到就是你还没有配置目的端口咯

Ruijie(config)#monitor session 1 source interface gigabitEthernet 0/1 both      ------>指定端口镜像的源端口为g0/1，即被监控端口，交换机可以指定多个源端口。both表示双方向的数据流，如果只需要镜像进入交换机方向的数据流，则将both关键字改为关键字rx，命令就变为了：monitor session 1 source interface gigabitEthernet 0/1 rx。如果只需要镜像从交换机出来方向的流量，则可将both关键字改为tx。

Ruijie(config)#monitor session 1 source interface gigabitEthernet 0/2 both     ------>指定端口镜像的源端口g0/2，即被监控端口。交换机可以指定多个源端口。both表示双方向的数据流，如果只需要镜像进入交换机方向的数据流，则将both关键字改为关键字rx，如果只需要镜像从交换机出来方向的流量，则可将both关键字改为tx。

Ruijie(config)#monitor session 1 destination interface gigabitEthernet 0/24 switch   ------>指定g0/24口为端口镜像的目的端口，即监控端口。后面加了一个关键字swith，表示目的端口也能够上网，如果不加关键字，那么该端口将不能访问外网。

哪位高手帮我分析一下，这是上面原因，它连接下面得交换机老是断开，谢谢

指48口神速的down就up？估计是硬件故障，找售后吧
