The precedence used to select one rule over potentially multiple rules that might match an L3/L4 flow. The rule with highest precedence takes precedence over any rule that specifies a matching flow, individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
