ROUTER > STATUS > IP STATS > IP

View the IP statistics from this menu.

DEFAULT TTL

The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this

unit, whenever a TTL value is not supplied by the transport layer protocol.

IP DATAGRAMS RECEIVED

The total number of input datagrams received from interfaces, including those received in error.

BAD HEADER PACKETS

The number of input datagrams discarded due to errors in their IP headers, including bad check sums,

version number mismatch, other format errors, time-to-live exceeded, errors discovered in

processing their IP options, etc.

BAD IP ADDRESSES

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 unit. 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.

TOTAL FORWARDED DATAGRAMS

The number of input datagrams for which this unit 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 unit, and the Source-Route option processing was successful.
