SLIP Parameters
The Serial Line Interface Protocol (SLIP) parameters appear in the first Network Statistics
Screen (Figure 5-10). 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.
Packets Dropped - Buffer
The Packets Dropped - Buffer field shows the number of incoming packets that were dropped
because there was not enough free memory to buffer them.
Buffer Overflow
The Buffer Overflow field shows the occurrences of buffer overflow at the local system.
Packets Sent Out
The Packets Sent Out field shows the number of packets transmitted by the local system to the
network host.
