The value of the object tIPv6FilterParamsExtPktLenVal2 specifies the packet length value2 to be compared to the value of the Payload Length field of an IPv6 packet header that has hit this filter's entry. The way how the value of this object is used depends on the value of the object tIPv6FilterParamsExtPktLenOper. The value of this object is evaluated only if the value of the object tIPv6FilterParamsExtPktLenOper is 'range (2)'. The value of this object must be greater than the value of tIPv6FilterParamsExtPktLenVal1. If both the values of the objects tIPv6FilterParamsExtPktLenOper and tIPv6FilterParamsExtPktLenVal2 need to be changed then it must be done in the same SET SNMP request. 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 tIPv6FilterParamsExtPktLenOper is set to a value other than 'range (2)' or if tIPv6FilterParamsExtHopLimitOper is set to a value other than 'none (0)'.
