The value of the object tIPv6FilterParamsExtHopLimitVal1 specifies the Hop Limit value1 to be compared to the value of the Hop Limit 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 tIPv6FilterParamsExtHopLimitOper. The value of this object can be set to a non-default value only if the value of the object tIPv6FilterParamsExtHopLimitOper is other than 'none (0)'. If the value of tIPv6FilterParamsExtHopLimitOper is 'range (2)' then the value of this object must be less than the value of tIPv6FilterParamsExtHopLimitVal2. If the value of tIPv6FilterParamsExtHopLimitOper is 'lt (3)' then the value of this object can be set in range 1..255. If the value of tIPv6FilterParamsExtHopLimitOper is 'gt (4)' then the value of this object can be set in range 0..254. If both the values of the objects tIPv6FilterParamsExtHopLimitOper and tIPv6FilterParamsExtHopLimitVal1 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 tIPv6FilterParamsExtHopLimitOper is set to 'none (0)' or if tIPv6FilterParamsExtPktLenOper is set to a value other than 'none (0)'.
