OUTER TATUS
View the IP statistics from this menu.
D TTL
EFAULT
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 D R
ATAGRAMS ECEIVED
The total number of input datagrams received from interfaces, including those received in error.
B H P
AD EADER ACKETS
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.
B IP A
AD DDRESSES
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.
T F
OTAL ORWARDED
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.
B P D
AD ROTOCOL ISCARDS
The number of locally-addressed datagrams received successfully but discarded because of an
unknown or unsupported protocol.
