IP Statistics
The IP Statistics screen provides statistical information about packets/connections using an IP protocol. Defi-
nitions and descriptions of each parameter are described below:
Figure 51. IP statistics
•
Forwarding
: Specifies whether IP forwarding is enabled or disabled.
•
DefaultTTL
: Specifies the default initial time to live (TTL) for datagrams originating on a
particular computer.
•
InReceives
: Shows the number of datagrams received.
•
InHdrErrors
: Shows the number of datagrams received that have header errors. Datagrams Received
Header Errors is 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 pro-
cessing their IP options, etc.
•
InAddrErrors
: Specifies the number of datagrams received that have address errors. These datagrams are dis-
carded because the IP address in their IP header’s destination field was not a valid address to be received at
this entity. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported
Classes (for example, Class E).
•
ForwDatagrams
: Specifies the number of datagrams forwarded.
•
InUnknownProtos
: Specifies the number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
•
InDiscard
: Specifies the number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but which were discarded (for example, for lack of buffer space). This counter
does not include any datagrams discarded while awaiting reassembly.
