1、实验拓扑

2、交换机配置

4F-IDC-01配置

vlan 100

remote-span

monitor session 1 source vlan 13

monitor session 1 destination remote vlan 100

4F-IDC-04配置

vlan 100

remote-span

monitor session 2 destination interface Gi0/7 ingress untagged vlan 13

monitor session 2 source remote vlan 100 

3、注意事项

4F-IDC-04#show ip int brief | include GigabitEthernet0/7 

GigabitEthernet0/7     unassigned      YES unset  up                    down   

配置完RSPAN接口的协议状态是down的，但是镜像配置实际上已经生效!
