6.3. IP Statistics
The IP Statistics screen provides statistical information about packets/connections using an IP
protocol. Definitions and descriptions of each parameter are described below:
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 processing their IP options, etc.
InAddrErrors :
Specifies the number of datagrams received that have address errors. These datagrams are
discarded 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).
