Understanding How QoS Works
IP ACE Layer 4 UDP Classification Criteria
You can create User Datagram Protocol (UDP) ACEs that match traffic for specific UDP source and/or
destination ports by including UDP port parameters (for more information, see the
Traffic" section on page
these keywords:

bootpc
bootps
discard

dnsix
UDP ACEs that do not include a Layer 4 UDP port parameter match all UDP traffic.
Note
IP ACE Layer 4 ICMP Classification Criteria
You can create Internet Control Management Protocol (ICMP) ACEs that match traffic containing
specific ICMP messages by including ICMP types and, optionally, ICMP codes (for more information,
