94 Chapter 3: EIU datafill
297-8991-910 Standard 03.01 August 1999
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.
Sample datafill for table IPPROTO
Figure 20 shows sample datafill for table IPPROTO.

Field Subfield or
refinement Entry Explanation and action
IPRSMTMO 1 to 100
(seconds) The IP reassembly time-out. This field
sets the time when IP reassembly gives
up reassembling a packet.
By default the IP reassembly time-out is
10 seconds. The time-out can be
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
(seconds) ARP cache time-out. On slow networks,
the ARP cache time-out can be
increased from the default of 1minute.
Increasing the time-out too much can
cause an excessively large ARP cache,
thereby reducing the network
performance.
