What is cmTrafficAclTcpUdpSrcPortMask?

This object specifies the maximum source port number to be used when filtering TCP or UDP traffic in an Access Control List rule. It works with other port configuration objects to define the range of source ports allowed or blocked. Network operators use this to implement granular traffic filtering policies that control which applications and services are permitted on the network.
