Global QoS classifier precedence: 1

When you use TCP or UDP and a Layer 4 Application port number as a global QoS classifier, traffic carrying the specified TCP/UDP port numbers is marked with a specified priority level, without regard for any other QoS classifiers in the switch. You can configure up to 50 TCP/UDP application port numbers as QoS classifiers.

NOTE:

Starting in software release K.14.01, global TCP/UDP classifiers are supported on IPv4, IPv6, or both IPv4 and IPv6 packets. In previous releases, only IPv4 packets were supported.
