To configure the maximum transmission unit (MTU) for each
link,
perform one of these actions:
In the Network Configuration Manager's Advanced Options
window for SLIP link configuration, set the
Maximum transmission unit (MTU) to the desired value in bytes.
Edit the slattach line in /etc/tcp or
the incoming login script to
contain the -m flag.
This flag is in the form
-mvalue, where value is a number in bytes.
The default MTU value is 296. Increasing this value
may increase throughput
as packets can contain more data. However, it may also decrease throughput
if packets are routed through systems with lower MTU values,
as each packet is split (fragmented) into smaller packets for transmittal.
You can experiment with this value to obtain the most desirable
results.
NOTE:
The suggested value for the MTU is 40 plus some power of
2. For example, the default value, 296, is 40 plus 2^8.
Other possible values include 552, 1064, and 2088.
