Example of configuring local port mirroring with multiple
monitor ports
Network requirements
As shown in Figure 49, Dept. A, Dept. B, and Dept. C are connected to Switch A through ports Ethernet
1/0/1, Ethernet 1/0/2, and Ethernet 1/0/3 respectively. Configure port mirroring to enable all three
data monitoring devices, Server A, Server B, and Server C, to monitor both the incoming and outgoing
traffic of the three departments.
