IP Statistics
Name
Description
F
ORWARDING
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).
D
EFAULT
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.
I
N
R
ECEIVES
The total number of input datagrams received from interfaces, including those
received in error.
I
N
H
DR
E
RRORS
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.
I
N
A
DDR
E
RRORS
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.
F
ORW
D
ATAGRAMS
The number of input datagrams for which this ATLAS 550 was not their final IP
destination, as a result of which an attempt was made to find a route to forward
them to that final destination. In entities which do not act as IP Gateways, this
counter will include only those packets which were Source-Routed via this
ATLAS 550, and the Source-Route option processing was successful.
I
N
U
NKNOWN
P
ROTOS
The number of locally-addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
I
N
D
ISCARDS
The number of input IP datagrams for which no problems were encountered to
prevent their continued processing, but which were discarded (e.g., for lack of
buffer space). Note that this counter does not include any datagrams discarded
while awaiting re-assembly.
