94Chapter 3: EIU datafill
If there is a serious performance problem, typically on very slow networks, modification of this table may be considered to increase timeout values.
Datafill sequence and implications
There are no datafill sequence and implications.
Datafill
Table 23 lists the fields and value ranges used to datafill an EIU in table
IPPROTO.

IPRSMTMO |
| 1 to 100 | The IP reassembly |
|
| (seconds) | sets the time when IP reassembly gives |
|
|
| up reassembling a packet. |
|
|
| By default the IP reassembly |
|
|
| 10 seconds. The |
|
|
| modified to improve performance in |
|
|
| extreme network conditions. On |
|
|
| extremely slow networks this may be |
|
|
| increased to give reassembly a better |
|
|
| chance to reassemble before the time- |
|
|
| out occurs. |
ARPRFTMO |
| 1 to 720 | ARP cache |
|
| (seconds) | the ARP cache |
|
|
| increased from the default of 1minute. |
|
|
| Increasing the |
|
|
| cause an excessively large ARP cache, |
|
|
| thereby reducing the network |
|
|
| performance. |
