The value of the object tIPv6FilterParamsExtPktLenOper specifies the way how the values of the objects tIPv6FilterParamsExtPktLenVal1 and tIPv6FilterParamsExtPktLenVal2 are used to form a condition that must be fulfilled in order to execute the action specified by the value of tIPv6FilterParamsAction. Otherwise the opposite action is executed. The value of this object can be set to a non-default value only if the value of the object tIPv6FilterParamsAction is 'drop (1)'. If the value of this object is being changed from the default value to any non-default value the values of the objects tIPv6FilterParamsExtPktLenVal1 and tIPv6FilterParamsExtPktLenVal2 (if applicable) must be sent in the same SET SNMP request. If the value of this object is 'none (0)' than the values of the objects tIPv6FilterParamsExtPktLenVal1 and tIPv6FilterParamsExtPktLenVal2 are ignored and TRUE case action is always executed (see table below). If the value of this object is 'eq (1)' then the value of the Payload Length field of the IPv6 header of the packet that has matched this filter's entry must be equal to the value of the object tIPv6FilterParamsExtPktLenVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPv6FilterParamsExtPktLenVal2 is ignored. If the value of this object is 'range (2)' then the value of the Payload Length field of the IPv6 header of the packet that has matched this filter's entry must be greater than or equal to the value of the object tIPv6FilterParamsExtPktLenVal1 and less than or equal to the value of the object tIPv6FilterParamsExtPktLenVal2 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. If the value of this object is 'lt (3)' then the value of the Payload Length field of the IPv6 header of the packet that has matched this filter's entry must be less than the value of the object tIPv6FilterParamsExtPktLenVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPv6FilterParamsExtPktLenVal2 is ignored. If the value of this object is 'gt (4)' then the value of the Payload Length field of the IPv6 header of the packet that has matched this filter's entry must be greater than the value of the object tIPv6FilterParamsExtPktLenVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPv6FilterParamsExtPktLenVal2 is ignored. tIPFilterParamsAction | TRUE case action | FALSE case action drop | drop | forward Allowed ranges for the values of tIPv6FilterParamsExtPktLenVal1 and tIPv6FilterParamsExtPktLenVal2 are: Operator |Packet Length Value 1|Packet Length Value 2 none (0) | N/A | N/A eq(1) | 0..65535 | N/A range(2) | 0..65534 | (Value1 + 1)..65535 lt(3) | 1..65535 | N/A gt(4) | 0..65534 | N/A The values of the objects tIPv6FilterParamsExtPktLenVal1 and tIPv6FilterParamsExtPktLenVal2 are silently cleared if the value of this object is set to default. Note that the value of this object is silently cleared by the system if tIPv6FilterParamsAction is set to a value other than 'drop (1)' or if tIPv6FilterParamsExtHopLimitOper is set to a value other than 'none (0)'.
