I. Network requirements
The departments of a company connect to each other through Ethernet switches:
Research and Development (R&D) department is connected to Switch C through
GigabitEthernet 1/0/1.
Marketing department is connected to Switch C through GigabitEthernet 1/0/2.
Data monitoring device is connected to Switch C through GigabitEthernet 1/0/3
The administrator wants to monitor the packets received on and sent from the R&D
department and the marketing department through the data monitoring device.
Use the local port mirroring function to meet the requirement. Perform the following
configurations on Switch C.
Configure GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 as mirroring source
