The value of the object tIPvXFltrEntryActPktLenVal1 specifies the value1 to be compared to the value of 'Total Length' field of IPv4 header or 'Payload Length' field of IPv6 header of an IP packet that has hit this filter's entry. The way how the value of this object is used depends on the value of the object tIPvXFltrEntryActPktLenOper. The value of this object can be set to a non-default value only if the value of the object tIPvXFltrEntryActPktLenOper is other than 'none (0)'. If the value of tIPvXFltrEntryActPktLenOper is 'range (2)' then the value of this object must be less than the value of tIPvXFltrEntryActPktLenVal2. If the value of tIPvXFltrEntryActPktLenOper is 'lt (3)' then the value of this object can be set in range 1..65535. If the value of tIPvXFltrEntryActPktLenOper is 'gt (4)' then the value of this object can be set in range 0..65534. If both the values of the objects tIPvXFltrEntryActPktLenOper and tIPvXFltrEntryActPktLenVal1 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 tIPvXFltrEntryActAction is set to a value other than 'dropPktLen' or 'rateLimitPktLen'.
