T X S TATS Read security: 5
Displays the number of ping requests transmitted (
n TXED ), the number of
ping replies received ( n RXED ) and the number of ping requests that were
lost ( n LOST ).
R ESET S TATS Write security: 5; Read security: 5
Resets all ping statistics to zero. If the ping client is active, this menu will
stop it.
S TART /S TOP Write security: 5; Read security: 5
If the ping client is currently idle, this menu sends pings to the specified
address. If the ping client is active, the menu stops sending pings.
S TATISTICS This section describes the statistics submenus IP , ICMP , TCP , UDP , and IP
F AST C ACHE . All of these statistics are taken from the MIB-2 variables in
RFC 1156.
IP Table 9-1 describes the IP statistics.

Name Description
Forwarding The indication of whether thisATLAS 550 is acting as an IP gateway in
respect to the forwarding of datagrams received by, but not addressed to, this
ATLAS 550. IP gateways forward datagrams; hosts do not (except those
Source-Routed via the host).
Default TTL The default value inserted into the Time-To-Live field of the IP header of
datagrams originated at this ATLAS 550, whenever a TTL value is not
supplied by the transport layer protocol.
InReceives The total number of input datagrams received from interfaces, including those
received in error.
InHdrErrors The number of input datagrams discarded due to errors in their IP headers,
including bad checksums, version number mismatch, other format errors,
time-to-live exceeded, errors discovered in processing their IP options, etc.
InAddrErrors The number of input datagrams discarded because the IP address in their IP
header's destination field was not a valid address to be received at this
ATLAS 550. This count includes invalid addresses (e.g., 0.0.0.0) and
addresses of unsupported Classes (e.g., Class E). For entities which are not
IP Gateways and therefore do not forward datagrams, this counter includes
datagrams discarded because the destination address was not a local
address.
