This read-create object sets the three TOS Precedence bits in the IP Type of Service field for APPN traffic sent to this connection network, applying to all traffic from this node regardless of which port it exits through. Admins use it to apply consistent QoS marking for a connection network's traffic across every port that reaches it, with changes taking effect immediately via Set rather than waiting for a reinitialization event. Raising hprIpCnTOSPrecedence for a connection network used by a critical APPN application ensures that traffic gets consistent priority no matter which local port it happens to route through.
