20 TCP/IP AXEL Platine Terminal

2.5 - STATISTICS

The Platine terminal monitors network performance from the time it is switched

on. The logs record details of exchanged frames, rejected frames, etc. The

'statistics' menu may be used to access these logs.

Ethernet

ARP

ICMP

TCP Client

TCP Server

These statistics are mainly intended for network administration tasks, such as

error diagnosis or network optimization. This manual only describes the

Ethernet, the ARP and the TCP (Client and Server) options.

2.5.1 -'Ethernet' Option

This option provides statistics relating to the embedded AX3000 Ethernet

controller. Out of 16 parameters, the main ones are:

- intr: number of interrupts received by the Platine terminal. Generally,

one interrupt is raised for each received frame (but sometimes one

interrupt is raised for multiple frames).

- short: number of received frames with a truncated (too short) header.

- dribble: number of received frames with an incorrect header.

- crc: number of received frames with an incorrect CRC.

- good: number of correct frames received.

- unktype: number of non-IP or non-ARP frames received (IPX frames,

for example).

- output: total number of frames sent by the Platine terminal.

- drop: number of dropped frames (because the input queue overflows).

- nomem: number of dropped frames (because of shortage of memory).

2.5.2 - 'ARP' Option

This option is used to display statistics about 'ARP' requests (Address

Resolution Protocol) which have been sent to, or received from, the Platine
