SW1(config)#hostnameSW1；设置交换机的主机名
SW1(config)#enablesecretcisco；设置特权加密口令
SW1(config)#enablepasswordcisco；设置特权非密口令
SW1(config)#lineconsole0；进入控制台口
SW1(config-line)#login；允许登录
SW1(config-line)#passwordcisco1；设置登录口令xx
SW1(config)#linevty04；进入虚拟终端
SW1(config-line)#login；允许登录
SW1(config-line)#passwordcisco2；设置登录口令xx
SW1#exit；返回命令

****************配置ACL****************

****************端口镜像：3560****************
监听指定vlan
SW5#showmonitor检查是否已存在镜像的配置
SW5#conft进入全局模式
SW5(config)#nomonitorsession1
SW5(config)#monitorsession1sourcevlan3-5both监控vlan3-5
SW5(config)#monitorsession1destinationintf0/23把信息复制到f0/23
SW5(config)#end返回
SW5#showmonitor

监听指定端口SW5#showmonitor检查是否已存在镜像的配置SW5#conft进入全局模式SW5(config)#nomonitorsession1SW5(config)#monitorsession2sourceintf0/24both监控端口f0/24SW5(config)#monitorsession2destinationintf0/23把信息复制到f0/23SW5(config)#end返回SW5#showmonitorsession2经过以上配置后,就可以用sinffer进行抓包了!
