This section describes the following STATISTICS submenus (see the tables below and on the pages
following):
• IP (see Table 6)
• ICMP (see Table 7 on page 229)
• TCP (see Table 8 on page 230)
• UDP (see Table 9 on page 231)
• IP Fast Cache (see Table 10 on page 231)
All of these statistics are taken from the MIB-II variables in RFC 1156. To clear the accumulated statistics,
press <Enter> or CLEAR.

Name Description
FORWARDING The indication of whether this ATLAS 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.
