Network Requirements
The user's network is as described below:
z Host A (with the IP address 192.168.0.1) and Host B are connected to GigabitEthernet 2/0/1 of
the switch.
z The data monitoring device is connected to GigabitEthernet 2/0/2 of the switch.
It is required to monitor and analyze packets sent by Host A on the data monitoring device.

# Create traffic behavior 1 and configure the action of mirroring traffic to GigabitEthernet 2/0/2 for the
traffic behavior.
