1.Cisco系列交换机配置端口镜像
cisco#conf t //进入全局配置模式
Enter configuration commands, one per line. End with CNTL/Z.
cisco(config)#monitor session 1 source interface g5/1 ?
, Specify another range of interfaces //不连续地指定多个源镜像端口
- Specify a range of interfaces //连续地指定多个源镜像端口
both Monitor received and transmitted traffic //将发送与接收均作镜像
rx Monitor received traffic only //仅将收到的流量作镜像
tx Monitor transmitted traffic only //仅将发送的流量作镜像
<cr>
cisco(config)#monitor session 1 source interface g5/1 //指定g5/1为源镜像端口,缺省为both
cisco(config)#monitor session 1 destination interface g5/8 //指定g5/8为镜像目的端口
cisco#sh monitor session ? //查看配置的镜像端口状态
<1-16> SPAN session number
all Show all SPAN sessions
erspan-destination Show only Destination ERSPAN sessions
erspan-source Show only Source ERSPAN sessions
local Show only Local SPAN sessions
range Show a range of SPAN sessions in the box
remote Show only Remote SPAN sessions
cisco#sh monitor session 1
Session 1
---------
Type : Local Session
Source Ports :
Both : Gi5/1
Destination Ports : Gi5/8
Encapsulation : Native
Ingress : Disabled
Learning : Disabled
Filter Pkt Type :
RX Only : Good
注意:启用了端口镜像的端口,在查看端口时会发现协议为none,是正常情况,表示该接口不再运行其他协议
2.H3C系列交换机配置端口镜像抓包
[H3C]monitor-port g0/10 //设置镜像端口即监控端口 10 为交换机端口编号
[H3C]mirroring-port g0/23 //设置被镜像端口即被监控端口 23 为交换机端口编号,如果需要多个连续的端口的命令式 mirroring-port g0/3 to mirroring-port g0/22即为被监控端口为编号3-22口。取消被监控端口的方法为 undo mirroring-port g0/XXX
[H3C]dis mir //显示所有端口镜像信息
Monitor-port:
GigabitEthernet0/10
Mirroring-port:
GigabitEthernet0/23
[H3C]q //退出端口镜像设置
[H3C]save //将配置后的信息保存
This will save the configuration in the EEPROM memory
