The value of the object tIPFilterParamsExtTTLOper specifies the way how the values of the objects tIPFilterParamsExtTTLVal1 and tIPFilterParamsExtTTLVal2 are used to form a condition that must be fulfilled in order to execute the action specified by the value of tIPFilterParamsAction. 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 tIPFilterParamsAction 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 tIPFilterParamsExtTTLVal1 and tIPFilterParamsExtTTLVal2 (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 tIPFilterParamsExtTTLVal1 and tIPFilterParamsExtTTLVal2 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 Time-To-Live field of the IP header of the packet that has matched this filter's entry must be equal to the value of the object tIPFilterParamsExtTTLVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPFilterParamsExtTTLVal2 is ignored. If the value of this object is 'range (2)' then the value of the Time-To-Live field of the IP header of the packet that has matched this filter's entry must be greater than or equal to the value of the object tIPFilterParamsExtTTLVal1 and less than or equal to the value of the object tIPFilterParamsExtTTLVal2 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 Time-To-Live field of the IP header of the packet that has matched this filter's entry must be less than the value of the object tIPFilterParamsExtTTLVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPFilterParamsExtTTLVal2 is ignored. If the value of this object is 'gt (4)' then the value of the Time-To-Live field of the IP header of the packet that has matched this filter's entry must be greater than the value of the object tIPFilterParamsExtTTLVal1 in order to execute the TRUE case action (see table below). Otherwise the FALSE case action is executed. The value of the object tIPFilterParamsExtTTLVal2 is ignored. tIPFilterParamsAction | TRUE case action | FALSE case action drop | drop | forward Allowed ranges for the values of tIPFilterParamsExtTTLVal1 and tIPFilterParamsExtTTLVal2 are: Operator | Time-To-Live Value 1| Time-To-Live Value 2 none (0) | N/A | N/A eq(1) | 0..255 | N/A range(2) | 0..254 | (Value1 + 1)..255 lt(3) | 1..255 | N/A gt(4) | 0..254 | N/A The values of the objects tIPFilterParamsExtTTLVal1 and tIPFilterParamsExtTTLVal2 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 tIPFilterParamsAction is set to a value other than 'drop (1)' or if tIPFilterParamsExtPktLenOper is set to a value other than 'none (0)'.
