Filtering packet data to display configuration example
Network requirements
On Switch A, capture the following incoming IP packets on Ten-GigabitEthernet 1/0/1:
Packets forwarded through the CPU.
Packets that are sourced from 192.168.56.1 and forwarded through chips.
Configuration procedure
# Create an IPv4 advanced ACL to match packets that are sourced from 192.168.56.1.

# Configure a traffic class to use the ACL to match traffic.
