7.4.2.1 SLIP Parameters
The Serial Line Interface Protocol (SLIP) parameters appear in the first Network Statistics
Screen (Figure 7-15). These are described below.
MTU Size
The MTU (Maximum Transmission Unit) Size field shows the largest number of user-data
(e.g., the largest size packet) that can be sent in a single frame. The MTU for this system is
240 bytes.
Bytes Received
The Bytes Received field shows the number of bytes received by the local system from the
network host.
Packets Received
The Packets Received field shows the number of packets (unit of bytes, roughly similar to an
IP datagram) received by the local system from the network host.
Packets Discarded
The Packets Discarded field shows the number of packets sent by the network host that were
discarded by the local system. Packets are discarded because they either exceed the MTU or
are not complete.
Action Function
pgUp Scrolls backward through network statistics, one page at a time. If you are
on the first screen (Page 1), automatically “wraps around” back to the fourth
screen (Page 4).
pgDn Scrolls forward through network statistics, one page at a time. If you are on
Page 4, automatically “wraps around” back to Page 1.
Refresh Since the system does not update statistics automatically, the Refresh
command must be used to update information in statistics fields.
Main Returns to the TCP/IP Screen. If changes are made to settings and not
saved, you will be prompted to save or lose changes.
