Any packets that have a frame size larger than the sizespecified are fragmented.Possible values are 160 to 800 bytes.The default value is 256 bytes.Delay Time This parameter is only available if you selected DelayTime for the Fragmentation Triggerparameter.Enter the maximum delay time, in milliseconds, for the packets. If the delay time exceeds thisvalue the packets are fragmented.Possible values are 10 to 40 milliseconds.The default value is 10.Low Water Mark This is one of the parameters that controls the link layer queuing behavior for PPP when link layerfragmentation is enabled.Possible values are 1 to 7.The default value is 6.Note: Nortel Networks highly recommends that you do not change the Low Water Mark from thedefault value.High Water Mark This is one of the parameters that Controls the link layer queuing behavior for PPP when linklayer fragmentation is enabled.Possible values are 2 to 8.The default value is 7.Note: Nortel Networks highly recommends that you do not change the High Water Mark from thedefault value.Note: The High Water Mark must be a larger than the Low Water Mark.Table 24 PPP Parameters (Continued)Attribute Description
