An ARP or RARP request is a request to determine the Ethernet number of a

host, whose IP address has been given for a terminal-to-host connection

The first part of the ARP and RARP statistics displays requests, which have

been sent to, or received from, the Office Server:

RARP:

- received: number of received RARP frames.

- bad-type: wrong frames.

- bad-len: frame length errors.

- replies-in: responses to RARP requests sent from the Office

Server.

- request-out: RARP requests sent from the Office Server.

ARP:

- received: number of received ARP frames.

- bad-type: wrong frames.

- request-in: ARP requests received by the Office Server.

- replies-in: responses to ARP requests sent from the Office Server.

- request-out: ARP requests sent from the Office Server.

Next, all recognised 'IP Address/Ethernet Address' associations are listed

with the following parameters (ARP table):

- IP addr: IP address

- Type: Ethernet

- Time: number of seconds before this table entry will be dropped

- Q: number of frames which are waiting for address resolution (Ethernet

address is 'unknown')

- Addr: Ethernet address associated with the IP address

c - IP Statistics

This option provides statistics relating to the IP layer:

- total: frames sent to, or received from, the Office Server

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

- length-err: frame length errors

- version-err: version errors

- chksum-err: checksum errors
