Locate the product activity log and work with your service provider to determine why your IP packets are being discarded.
This function is typically used at the request of your service provider.
To work with the product activity log, you must have *SERVICE
special authority. See the chapter on user profiles in iSeries™ Security Reference 
for more
information about this type of authority.
Use the product activity log to view error log data. Whenever a TCP/IP datagram is discarded because of a protocol error, the TCP/IP Licensed Internal Code creates an entry in the product activity log.
- Outbound datagrams - For outbound TCP/IP datagrams, an error is reported to the user and the outbound datagram is discarded. For example, you try to send a datagram over your X.25 connection, but the connection fails.
- Inbound datagrams - Inbound datagrams cause an entry in the product activity
log to be created when both of these conditions are met:
- The Log protocol errors TCP/IP attribute is set to *YES.
- The datagram has failed one of the TCP/IP protocol validity tests specified in RFC 1122, causing the system to discard it. (Silently discarded means the following: Discard the received datagram without reporting an error to the originating host device.) Examples of such datagrams are those with checksums or destination addresses that are not valid.
When a datagram is discarded, the IP and TCP or UDP datagram headers are logged in the detailed data of the product activity log entry. The system reference code for these product activity log entries is 7004.
