2. Configure an observing port.
# Configure GigabitEthernet 0/0/24 as the observing port.

3. # Create a traffic classifier.
# Create traffic classifier c1 and set the traffic classification rule that only the packets with
the 802.1p priority as 6 can be matched.

4. # Create a traffic behavior.
# Create traffic behavior b1 and configure flow mirroring in the traffic behavior.

5. Create a traffic policy.
# Create a traffic policy and bind traffic classifier c1 to traffic behavior b1.

6. Apply the traffic policy and enable the interface to trust the 802.1p priority of packets.
# Apply traffic policy p1 to GigabitEthernet 0/0/1 and GigabitEthernet 0/0/5, and enable
GigabitEthernet 0/0/1 and GigabitEthernet 0/0/5 to trust the 802.1p priority of packets.
